The document summarizes the major stratigraphic sequences in the Jeanne d'Arc basin offshore Newfoundland, Canada and their relationship to the tectonic events of the opening of the North Atlantic. During the Late Jurassic to Early Cretaceous syn-rift phase, three regressive deltaic sediment pulses prograded into the basin from the southwest. A major transgression during the Aptian flooded the basin. From the late Albian, thermal subsidence led to a prolonged transgression interrupted by local regressions. In the lower Eocene/Paleocene, a sea level drop triggered submarine fan deposition sourced from the west. The major controls were tectonics from Atlantic rifting and the Avalon

Arctic ocean
The Arctic Ocean is the smallest and shallowest of the world's oceans, centered around the North Pole. It is surrounded by landmasses and its seas have seasonal or perennial ice cover, making it one of the least explored ocean basins. The Arctic Ocean may be highly sensitive to global climate change and could initiate dramatic climatic shifts through changes to ocean currents or the global albedo from alterations to its ice cover. The document then describes the ocean's origin from seafloor spreading, the sediments that provide evidence of its past warmer climate, its unique physical characteristics compared to other oceans like its extensive shallow marginal seas, and details of its water masses and circulation patterns.
Bujak Atlantic Paleogene talk
The document outlines a zonation scheme for the Paleocene-Eocene of the North Atlantic region that integrates plate tectonic events, mantle plume activity, oceanography, climate, and their effects on microfaunal assemblages. Uplift of the Greenland mantle plume during the late Paleocene and Paleocene-Eocene transition separated the region into three marine systems and caused shifts from calcareous to siliceous microfossils. Maximum uplift during the PETM exacerbated anoxia and biotic crises. Middle Eocene cooling steps associated with the greenhouse to icehouse transition caused diachronous extinctions between basins. The integrated scheme provides a robust chrono
Great ocean conveyor
The document summarizes the ocean's global conveyor belt circulation system. It describes how cold, dense water sinks near Iceland and flows south as the lower limb of the conveyor belt through the deep Atlantic. As it circulates around Antarctica, it mixes with other deep waters and loses its identity. About one part of the northern Atlantic deep water mixes with two parts of southern-sourced deep water to form the global deep water circulation. The upper limb returns water to the surface in the Pacific and Indian Oceans through upwelling that is more widespread than depicted by the iconic conveyor belt diagram.
Bujak Arctic Cenozoic talk
The past 66 million years, known as the Cenozoic Era, is particularly relevant to climate change because the world's climate changed from the greenhouse world of the dinosaurs to our modern icehouse world. But Cenozoic sediments in the Arctic are notoriously difficult to date using fossils (‘biostratigraphy’). The talk describes the methodology, based on 40 years work by Dr Jonathan Bujak, for establishing a biostratigraphic framework for the Cenozoic of the Arctic. This enables the history of the entire region to be correlated within the Arctic and with events in lower latitudes.

Azolla event talk june 2014 part 1
Part one of a two part talk describing a remarkable event that occurred in the Arctic 50 million years ago, when a unique floating freshwater plant called Azolla repeatedly covered the surface of the ocean for almost a million years. Due to its phenomenal growth, Azolla sequestered enormous quantities of the greenhouse gas carbon dioxide, and changed the Earth's climate from a greenhouse world towards our modern icehouse climate with its permanent ice and snow at both poles. 'The Arctic Azolla Event' was discovered by the Arctic Coring Expedition (ACEX) when it recovered sediments beneath the North Pole in 2004. The discovery was featured in the New York Times (November 20, 2004) and National Geographic (May 2005), and its validity has now been confirmed by international teams of scientists who have investigated and published on the cores, including a series of papers in the scientific journal ‘Nature’.

Semester Presentation 1
This document discusses post-glacial sea level change and isostatic rebound along the Northwestern coast of North America since the last glacial maximum. It examines six regions - Southern Cascadia, Northern Cascadia, Northern British Columbia, Outer Islands North Coast, Southeast Alaska Mainland, and South Central Alaska - and the various processes that have affected relative sea levels in each, including eustatic sea level change, isostatic depression and rebound, sedimentation, crustal deformation, and their complex interactions over time. The coastlines show diversity in these effects based on the extent and timing of glaciation and deglaciation in each local area.
South biscay gales
Abstract
South Biscay coastally trapped disturbances known as gales (galernas, enbatak, galarrenak, bruilartak) are adverse phenomena that send along the Cantabrian and Basque Coast a narrow jet of sudden and violent gusts of wind that do not follow a hydrostatic balance parameterization, being faster, stronger and of a Western-North-Westerly component, and accelerate as they rush Eastward enduring their speed and intensity. These gales run the coast line from West to East strengthening in Eastern Cantabrian Seashore line from May to October.
History of Glaciation
1) The study of glaciation is a relatively new field that began in the 1830s when Louis Agassiz discovered evidence of past glaciation in the Swiss Alps.
2) Ice core records from Greenland and Antarctica provide evidence of climate cycles over the past 800,000 years through analyzing trapped air bubbles and CO2 concentrations.
3) We are currently in the Quaternary period which began 2 million years ago, and the most recent ice age termed the Pleistocene epoch ended approximately 11,500 years ago at the conclusion of the Younger Dryas stadial period.
Biogeo lec 7 glaciation and the pleistocene
The document discusses glaciation and biogeography during the Pleistocene epoch. It describes the extent and causes of glaciation, including continental ice sheets covering one third of the earth's land mass. It discusses Milankovitch cycles and feedback effects that influenced glacial and interglacial periods. During glacial maxima, unglaciated regions were cooler and wetter while tropical regions were drier. Biogeographic responses of terrestrial biotas included shifts in climatic zones and sea level changes affecting island populations. Refugia like Nunataks provided opportunities for genetic divergence. Glacial lakes and pluvial lakes in arid regions fragmented habitats. Alternative hypotheses for Pleistocene extinctions beyond
P66094 special topic marine chem
The document discusses four key physical parameters in seawater: temperature, salinity, pressure, and pH. It describes how temperature varies based on latitude and is measured in degrees Celsius, Kelvin, or Fahrenheit. Salinity refers to the dissolved salt content measured in parts per thousand. Pressure increases with depth due to the weight of the overlying water and is measured in decibars. pH measures the acidity of seawater and affects biological and chemical reactions. Understanding variations in these physical parameters provides insight into ocean properties and processes.
Chapter 7 fetter regional groundwater flow
This document discusses groundwater flow patterns and regional groundwater systems. It covers topics such as recharge and discharge zones, effects of basin geometry, local vs regional flow systems, mapping flow systems using data on topography, piezometers, hydrochemistry, and isotopes. It also discusses interactions between groundwater and lakes/wetlands, noncyclical groundwater, saltwater encroachment issues and solutions, and quantitative analysis of recharge and discharge rates using flow net construction.
Cret seq strat_mid_Norway_London_Sept_2002 Charnock and Crittenden
This study presents a sequence stratigraphic framework for the Late Cretaceous interval in the offshore Mid-Norway area based on an extensive biostratigraphic review of wells. Key microfossil events are used to correlate sequence boundaries, transgressive surfaces, and surfaces of maximum marine transgression for integration with wireline logs and seismic data. Several periods of deep-water sandstone development within sequences are identified as potential reservoirs. Biostratigraphy played an important role in recognizing and correlating Late Cretaceous sequences in the region due to the predominantly claystone lithology masking stratigraphic breaks in wireline logs.
Lesson 1 History of Glaciation
The document discusses the history of glaciation. It explains that ice ages were first discovered in the 1830s and that ice cores have provided evidence of past climate changes over the last 800,000 years. Geological time is broken into periods like the Quaternary period, which includes the current Holocene epoch and the Pleistocene epoch during the last ice age. The causes of the glacial and interglacial cycles within the Pleistocene are thought to involve changes in the Earth's orbit and axis known as the Milankovitch cycles, as well as climate feedback mechanisms involving factors like albedo, cloud cover, and ocean currents. Short term climate fluctuations may also be influenced by solar activity and volcanic eruptions
EAGE2002presentation2
The document summarizes a reservoir characterization study of the Novogodneye Field in NW Siberia, Russia. The study utilized 3D seismic data to better understand the depositional environment and heterogeneity of the Jurassic reservoir. Horizon slices revealed deltaic depositional systems within the Jurassic interval. Undrilled potential sand bodies in the J1-1 reservoir were identified as targets for future horizontal wells. Reservoir models incorporating the facies distribution showed good history matches, allowing for forecasting. The study enhanced understanding of the Jurassic reservoir to improve well planning and field development.
Geothermal energy and ice and unlikely alliance?
An analysis of well temperature data and geothermal gradients provide insights for onshore geothermal opportunities as well as highlighting areas of recent hydrocarbon charge on the Norwegian Continental Shelf (NCS).
Higher gradients (> 40 degrees C/km) have been identified in a number of areas including; Southern North Sea Salt Diapirs, the Utsira High, the Peon Discovery, the Western Møre and Vøring Basins.
Area of higher gradients are often coincident with areas of recent (Neogene to Quaternary) hydrocarbon charge and fluid movement along significant vertical conduits such as salt diapirs, basement faults, dykes and hydrothermal vents. Many oil accumulations in these areas are associated with anomalously low biodegradation due to recent rapid charge.
Repeated ice sheet loading and unloading has resulted in very recent uplift, erosion, tilting, trap breach, fluid migration and fluid remigration and subsurface temperature changes.
Further analysis is proposed to determine the relative importance of conductive versus convective/advective heat flow and the influence of ice sheet loading and unloading has had on recent fluid and heat flow paths and subsurface temperature changes.
Retrospective analysis of hydrologic impacts in the Chesapeake Bay watershed
This document summarizes the results of using the Hydrologic Simulation Program FORTRAN (HSPF) model to simulate hydrologic impacts in the Chesapeake Bay watershed over 22 years. The model performed reasonably well at larger time scales but tended to overestimate peak flows and underestimate low flows. Statistical analysis found increasing streamflow trends correlated with increasing precipitation and land use changes. Peak flows were typically preceded by low flow years and high median flow years showed greater flow variability.
Week 6.2 millennial scale climate change
The document discusses millennial scale climate change from 21,000 years ago to present. At the last glacial maximum 21,000 years ago, large ice sheets covered northern regions. The climate was colder globally due to the ice sheets and lower greenhouse gas levels. From 21,000 to today, summer insolation increased and ice sheets melted in two steps, with a pause during the Younger Dryas event 12,000 years ago. Greenhouse gases like CO2 also rose as the ice melted. Shorter millennial scale climate oscillations occurred during deglaciation, but their causes are still debated among ice sheet dynamics, ocean currents, and possible solar influences.

Chapter 11 Fetter Groundwater Development
This document summarizes Palestinian water resources, including surface water like the Jordan River, and groundwater. It discusses the Western, Eastern, and Northeastern groundwater basins in the West Bank, and the coastal aquifer in Gaza. It notes that while the Jordan River is the most important surface water, groundwater is the primary source due to rainfall fluctuations. It also outlines processes that contribute to salinization of Gaza's groundwater and discusses artificial groundwater recharge as a way to address saltwater intrusion and water shortages. The document provides definitions for key water-related terms in Palestinian law.
Global warming, sea level rise and coastal inundation
Global warming is causing sea levels to rise faster than ever before due to melting ice sheets and glaciers. Over the last 100 years, sea levels have risen approximately 12-22 cm and are predicted to continue rising throughout the 21st century. Contributors to sea level rise include thermal expansion of oceans as they warm, and melting of glaciers and ice sheets in Greenland and Antarctica. Management strategies to deal with rising seas include reducing greenhouse gas emissions to slow warming, coastal defenses, and proposals to transfer large amounts of water from oceans to land storage.
Field and lab assignment part II
The document summarizes field work done at the San Andreas Fault in Park Field, California and weathering processes observed in Coalinga, California. It describes the San Andreas Fault as a right lateral-slip fault that marks the boundary between the Pacific and North American plates. It then discusses mechanical and thermal weathering observed along Coalinga Creek, including cracks in rocks from thermal stress weathering and erosion from water rushing through in the spring. Finally, it mentions using geology knowledge practically in the design and construction of the Coalinga Bridge over Coalinga Creek.
Earth science chp 14[1]
The document discusses key topics in oceanography including ocean floor features, seafloor sediments, and resources from the seafloor. It defines important terms like continental margin, continental shelf, continental slope, and mid-ocean ridge that describe features of the ocean floor. It also outlines the different types of sediments found on the seafloor including terrigenous, biogenous, calcareous ooze, and siliceous ooze sediments. Finally, it discusses resources extracted from the seafloor like gas hydrates and manganese nodules.
Millinial Scale
This document discusses climate change over various time periods from 1.5 million years ago to the present. It outlines major climate events and conditions during different millennia, including glacial periods and retreats, rising sea levels, changes in ocean currents, volcanic eruptions, and variations in greenhouse gases and solar activity that impacted global temperatures and weather patterns over thousands of years. Records of past climate changes come from sources like geological evidence, historical documents, and tree ring data.

Cuento El Ángel de los niños
Un niño que está por nacer habla con Dios y expresa su preocupación por vivir en la Tierra pequeño e indefenso. Dios le asegura que ha escogido un ángel para cuidarlo y protegerlo, que le cantará y sonreirá todos los días para hacerlo feliz. El ángel también le enseñará a comunicarse con los humanos y a rezar para regresar a la presencia de Dios. Antes de nacer, el niño pide a Dios el nombre de su ángel, a lo que Dios responde que no importa, ya

1) The document discusses evidence that supports the theory of continental drift, including matching coastlines, fossil and rock records that show continents were once joined in a supercontinent called Pangea.
2) It describes the process of sea floor spreading where new crust forms at mid-ocean ridges, cools, and magnetic signatures are recorded that allow scientists to measure spreading rates.
3) Plate tectonics involves the movement of plates driven by convection currents in the mantle, with creation of new crust at ridges and destruction at subduction zones, causing volcanism and earthquakes at plate boundaries.

Cycles of climatic changes
The document outlines cycles of climatic change during the Quaternary period, including glacial and interglacial periods. It discusses the Eemian/Sangamon interglacial 130,000-115,000 years ago, the Early-Middle Weichselian/Wisconsin glacial period 115,000-50,000 years ago, and the Last Glacial Maximum 20,000-18,000 years ago. During glacial periods, continental ice sheets grew and sea levels dropped globally. Interglacials were warmer with higher sea levels. Reconstructions show the extent of ice sheets and changes in ocean temperatures over this timeframe.

that is associated with broad upwarping of the overlying litho.docx
that is associated with broad upwarping of the overlying lithosphere (figure 5.1 iA). As a result, the lithosphere is stretched, causing the brittle crustal rocks to break into large slabs. As the tectonic forces continue to pull the crust apart, these crustal fragments sink, generating an elongated depression called a continental rift (figure 5.1 ib).
A modern example of an active continental rift is the East African Rift (figure s. i 2). Whether this rift will eventually result in the breakup of Africa is a topic of continued research. Nevertheless, the East African Rift is an excellent model of the initial stage in the breakup of a continent. Here, tensional forces have stretched and thinned the crust, allowing molten rock to ascend from the mantle. Evidence for recent volcanic activity includes several large volcanic mountains including Mount Kilimanjaro and Mount Kenya, the tallest peaks in Africa. Research suggests that if rifting continues, the rift valley will lengthen and deepen, eventually extending out to the margin of the landmass (r;<;ur.E 5.1 ic). At this point, the rift will become a narrow sea with an outlet to the ocean. The Red Sea, which formed when the Arabian Peninsula split from Africa, is a modern example of such a feature. Consequently, the Red Sea provides us with a view of how the Atlantic Ocean may have looked in its infancy (figure 5.1 id).

Forces Within sSWHBe Plate Tectonics
New lithosphere is constantly being produced at the oceanic ridges; however, our planet is not growing larger—its total surface area remains constant. A balance is maintained because older, denser portions of oceanic lithosphere descend into the mantle at a rate equal to seafloor production. This activity occurs along convergent (con = together, vergere = to move) boundaries, where two plates move toward each other and the leading edge of one is bent downward, as it slides beneath the other.
Convergent boundaries are also called subduction zones, because they are sites where lithosphere is descending (being subducted) into the mantle. Subduction occurs because the density of the descending tectonic plate is greater than the density of the underlying asthenosphere. In general, oceanic lithosphere is more dense than the asthenosphere, whereas continental lithosphere is

Geographical Tour of USA
The document summarizes the geological formation of several major North American geographical regions:
- Hawaii formed from volcanic activity at a hotspot under the Pacific plate over millions of years.
- Yellowstone National Park sits on a caldera formed by a large explosion around 17 million years ago, with geysers and thermal features caused by the North American plate moving over a mantle hotspot.
- The Canadian Shield was once a mountainous region but erosion left only remnants of igneous and metamorphic rock beneath a thin soil layer.
- The Basin and Range Province formed due to crustal extension causing normal faults and thinning of the lithosphere.

This document summarizes key information about fracture zones in the North Atlantic and Norwegian-Greenland Sea region based on lessons from the opening of the South Atlantic. It discusses how fracture zones were set up during earlier ocean openings and influenced basin architecture, reservoir distribution, migration pathways, and trap formation. It also describes how fracture zones on the eastern US seaboard were reactivated during the breakup of Pangaea and are still active today due to plate tectonic movements. Additionally, it summarizes the tectonic history of the Norwegian-Greenland Sea region and how a symmetric spreading model can explain its opening, with fracture zones influencing the region's structure and creating opportunities for hydrocarbon exploration.
Origin and destruction of ocean floor ppt ; ocean floor :evolution of ocean f...
The document discusses the evolution of ocean floors over time. It begins forming at mid-ocean ridges through sea floor spreading, as new crust is created and the continents diverge. Mature ocean basins develop and widen until beginning to decline due to continued spreading and shrinking. Finally, subduction eliminates most of the ocean crust and continents collide, forming mountain ranges. Sea floor spreading and subduction are the major forces driving the evolution of tectonic plates and the continuous formation and destruction of ocean floors according to the Wilson Cycle.
A Comparison of Structural Styles and Prospectivity along the Atlantic Margin...
1) The structural style of the Atlantic margin offshore West Africa shows differences between the passive rifted Northwest African Atlantic Margin (NWAAM) and the West African Transform Margin (WATM).
2) The WATM is characterized by basins between transform faults containing large Upper Cretaceous turbidite systems with proven oil discoveries, while the NWAAM contains multiple petroleum systems trapped against salt structures, in carbonate reefs, and in syn-rift structures.
3) Both regions remain largely untested, particularly the NWAAM in deepwater, and further exploration has potential to make new hydrocarbon discoveries.

The document summarizes volcanic activity in northern central Peru from the Cretaceous to present. It describes three groups of volcanic rocks separated in time and space: 1) The Albian Casma Group volcanic rocks which filled the Casma Basin in a deep sea environment during crustal extension. 2) The Calipuy Group volcanics from 53-15 Ma erupted during a period of extension. 3) The younger Miocene-Pliocene Yungay volcanic rocks associated with major batholith intrusion during transtensional faulting. Although the volcanic rocks are calc-alkaline, crustal extension played a fundamental role in their genesis, whereas their relation to contemporaneous subduction is less clear.

This document summarizes research on hydrothermal alteration in volcanic rocks on the south flank of Lassen Volcano in California. An active steam-heated system produces low-temperature alteration near surface, while older inactive systems produced zones of intermediate argillic and propylitic alteration. Over 200 rock samples were collected and analyzed to map alteration mineral distributions. Preliminary results identified zones dominated by clay minerals like illite/smectite, chlorite, and montmorillonite indicating both active and fossil hydrothermal systems affected the area.
Plate Tectonics
This document provides information about plate tectonics and is designed to meet South Carolina science standards. It discusses the layers of the Earth, tectonic plates and their movement, and the three types of plate boundaries - convergent where plates collide, divergent where they separate, and transform where they slide past each other. Specific examples are given for each boundary type, including discussions of sea floor spreading at mid-ocean ridges, subduction zones creating volcanoes and trenches, and the San Andreas Fault as a transform boundary.
Raised beaches and estuaries 2011
Scientists have mapped the remnants of a prehistoric landscape lying under the North Sea that was once above water. It contained human settlements, lakes, hills, coastlines, and rivers before being flooded by rising sea levels over 5,000 years ago at the end of the last ice age. The submerged landscape, called Doggerland, was larger than modern day Britain and was home to early humans and animals until it was overwhelmed by rising waters. Seismic data collected by oil companies revealed the sunken features of this lost world.

The document discusses the ages and life cycles of Hawaiian volcanoes. It notes that:
- MBARI bathymetry first revealed numerous flat-topped volcanoes on the seafloor around Hawaii.
- The mantle source generating the Hawaiian Islands is chemically heterogeneous between volcanoes and also varies over time within a single volcano.
- Any theory of Hawaiian volcanism must explain factors like the migration direction change at a bend, variations in magmatic production, and the unique characteristics of individual volcanoes.
Atlantic Margins- Miall, Balkwell and McCracken 2008
This document summarizes the geology of the Atlantic margin basins of North America. It discusses how the margin developed from the initial rifting of Pangea in the Triassic through ongoing sea floor spreading into the Cenomanian-Oligocene period. Sedimentary deposits along the margin can reach 25 km thick, consisting of rift basin deposits overlain by a prograding wedge of marine sediments, including widespread evaporites. Carbonate deposits were initially important but gave way to clastics as the continent drifted northwest. The margin developed through crustal thinning and detachment, with the Grand Banks area experiencing two phases of rifting related to extension in the central and North Atlantic. Major petroleum discoveries were made beneath
Glacial Outburst Flooding
1) Glacial Lake Missoula formed during the last ice age when an ice dam blocked the Clark Fork River, causing a huge lake to form. The lake drained catastrophically when the ice dam failed, carving out features like ripple marks and waterfalls.
2) These floods discharged at rates over 600 times the modern Amazon River and formed huge ripple marks up to 30 meters tall. Analysis of sediment layers indicates periods of both low and high energy deposition from the filling and draining of the lakes.
3) Flood waters from Lake Missoula entered a second ice-dammed lake, Glacial Lake Columbia, and found outlets through channels now known as the Channeled Sc

The document discusses using remote sensing data from the South Atlantic to develop a model for how the North Atlantic opened. It presents data on fracture zones in the South Atlantic and Jan Mayen region that divided the seafloor into depositional basins. A symmetric spreading model is proposed to explain North Atlantic opening from the Eocene to present, with plate motion changing in the Oligocene with the opening of Fram Strait. Lava flows obscure some magnetic anomalies but the model fits available data.
Geologic Evolution of the Grand Canyon
The Grand Canyon formed through a combination of uplift of the Colorado Plateau and incision by the Colorado River. Two main theories for its formation are the Headward Erosion Theory, which involves capture of an ancestral river by upstream erosion, and the Spillover Theory, where a blocked river spilled over the plateau. Both theories have issues, and the exact timeline and mechanisms are still debated. Uplift starting around 80 million years ago drove stream capture and erosion that excavated the canyon over millions of years.
Syn rift
1) The study analyzes the syn-rift architecture and depositional patterns in the Tanjore sub-basin of the Cauvery Basin through seismic facies analysis and integration of well data.
2) Four syn-rift units were identified, representing deposition during different stages of rift evolution - early rift, rift climax, and late rift. Unit 2, deposited during the rift climax stage, has good source rock potential, while Units 3 and 4 from the late rift stage contain favorable reservoir facies.
3) Preliminary 2D petroleum system modeling along a cross-section indicates potential hydrocarbon accumulation areas within the syn-rift sediments.

Paleogeography of Jeanne d'Arc Basin AAPG 2001
- 1. This paper was presented at the 1991 Annual AAPG Convention, Dallas Texas Paleogeography of the Mesozoic Jeanne d'Arc Basin, Grand Banks, Newfoundland, Canada MCCRACKEN, JOCK N., Mobil Oil Canada, Calgary, Alberta, Canada The major stratigraphic sequences of the Jeanne d'Arc basin, Grand Banks, offshore Newfoundland, Canada, and their relationship to the tectonic events involved in the opening of the North Atlantic are summarized. This basin has been a major exploration area for Mobil and industry since 1971. This activity has resulted in the shooting of over 300,000 km of reflection seismic lines and the drilling of 65 wells. Fifteen discoveries have been found in the basin to date by industry. The Hibernia project is underway with production planned in 1996. Government basin analysis estimates for total ultimate recoverable reserves in the Jeanne d'Arc basin range from 3.3 to 10 billion bbl of oil equivalent. The major stratigraphic events from the Late Jurassic to the Early Eocene within the Jeanne d'Arc basin are illustrated by six isometric paleogeographic reconstructions. These geological sequences are then related on the stratigraphic column to the tectonics and coastal onlap curves. During the Late Jurassic/Early Cretaceous syn-rift phase three regressive pulses of predominantly deltaic sediments (Jeanne d'Arc, Hibernia, and Avalon formations) prograded into the Jeanne d'Arc basin from the southwest with minor sediment contributions from the eastern and western perimeter highs. During Aptian time the Grand Banks separated from the Galicia Bank of Iberia creating a major transgression that flooded the basin and reworked the existing clastics (Ben Nevis Formation). At the end of Albian during the breakup of the Flemish Cap and the Goban Spur, thermal subsidence initiated a prolonged transgression that was only interrupted by local regressions. A relative drop in sea level in the lower Eocene/Paleocene then triggered submarine fan deposition (Topsail and Mara Formations) sourced from the west. The major controls on Jeanne d'Arc basin deposition were the tectonics created as a result of the northward propagation of the rifting of the Atlantic Ocean and its effect locally on the broad arch to the south called the Avalon Uplift. This provided the major clastic source throughout the Mesozoic. Changes in relative sea level then overprinted these tectonic events.
