This document discusses sedimentary petrology and the formation of sedimentary rocks. It defines sediments as materials formed by weathering and erosion of pre-existing rocks. Sediments are classified based on particle size, ranging from boulders and pebbles to clay. Sedimentary rocks form through the processes of sediment generation, transportation, deposition, compaction and cementation. The roundness of sediment particles provides clues about the distance of sediment transportation prior to deposition and lithification into sedimentary rock. Major rock types include clastic rocks derived from eroded particles or clasts, and non-clastic rocks formed by chemical or organic processes.

Sedimentary rock notes09
There are three main types of sedimentary rocks: clastic or terrigenous rocks which are formed from weathered and eroded fragments and can be deposited in continental, shoreline, or marine environments; biogenic rocks which are usually carbonate sediments classified by mineral composition and formed through biological processes in limited depositional locations; and chemical rocks which form from precipitation of salts from solution in both marine and non-marine environments, such as gypsum and halite.
Plant Project RL
Soil is made up of three basic units: sand, silt, and clay. Clay is the smallest particle and feels sticky when wet, forming heavy soils. Silt is easily transported by water and forms river deltas. Sand is the largest particle, ranging from 1/16 to 2 millimeters, feeling rough with sharp edges and not holding many nutrients or water.
The metamorphics rocks (1)
The document discusses different types of metamorphic rocks. It defines metamorphism as changes to rocks through heat and pressure. There are two main types of metamorphism: contact metamorphism near magma intrusions and regional metamorphism from high heat and pressure at depth. The document then describes several common metamorphic rocks including slate, gneiss, schist, marble, quartzite, and mica schist. It provides details on the color, texture, and typical mineral composition of each rock type.
Earthlayers rocks
The document discusses the different layers of the Earth, including the crust, mantle, inner core and outer core. It then provides analogies comparing the Earth's structure to an apple. Finally, it outlines the three main types of rocks - igneous, sedimentary, and metamorphic - and provides a brief description of how each type is formed through melting, layering of materials, and changes caused by pressure and heat respectively.

Report on sand
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is formed through the weathering and erosion of rocks and transported by wind and water. Sand is commonly divided into subcategories based on grain size, and its composition varies depending on the local rock sources. The most common type of sand found in coastal and continental areas is silica sand, usually in the form of quartz, which is very resistant to weathering. Sand has many uses including in construction, industrial applications like glassmaking, and recreational activities.

Sedimentary rocks form from the consolidation of sediments and are divided into clastic, chemical, and biochemical types. Clastic rocks like sandstone and shale form from weathered fragments transported by wind, water, or ice. Chemical rocks like limestone precipitate directly from solution. Biochemical rocks such as coal form from the remains of living organisms. Sedimentary structures and fossils within rocks provide clues about depositional environments. Sedimentary rocks are economically important resources for construction materials, energy, and industrial minerals.

The document discusses sedimentary rocks, describing their formation from weathering and erosion of pre-existing rocks. Sediment is transported via water or wind and sorted by size into gravel, sand, silt, or clay. Sediment is then deposited and may undergo lithification into sedimentary rock through compaction and cementation. The main types of sedimentary rocks are clastic (formed from fragments), chemical (formed from precipitation), and biochemical (containing organic material). Sedimentary structures provide clues about the environment of deposition, and the interpretation of these rocks can reveal information about past plate tectonic settings and conditions. Sedimentary rocks are an important source of non-metallic and energy resources.

Sand
This document discusses different types and properties of sand. It describes sand as a mixture of small rock and mineral particles between 0.06 mm and 2 mm in size. The main components of sand are quartz and feldspar. Sand comes in different colors depending on its mineral composition, and there are various types including river sand, sea sand, volcanic sand, and heavy mineral sand. Sand is classified based on particle size, with very fine, fine, medium, and coarse categories.
Defining basalt and sandstone.
Sandstone is a sedimentary rock composed of sand-sized grains of minerals and rock fragments bound together by a cement, such as silica or calcium carbonate. It forms under both marine and terrestrial environments. Sandstone has been widely used as a building material in structures like temples, homes, and monuments due to its hardness yet ability to be carved. It is also used for grindstones, statues, and filtering pollutants from water due to its porous nature. Major deposits of sandstone can be found around the world, including in the United States, South Africa, and Europe.
Igneous rocks
This document provides information about igneous rocks, including their classification, textures, and mineral compositions. It discusses how igneous rocks are formed by the cooling of magma and can be classified as intrusive or extrusive depending on where they solidify. Intrusive igneous rocks cool slowly below the Earth's surface, resulting in large crystal sizes, while extrusive rocks cool rapidly after erupting, producing small crystals. The document also examines different igneous rock textures that provide information about cooling rates, and explains how mineral compositions are determined by Bowen's Reaction Series during crystallization.
Why is Petrology important to Civil Engineering?
Petrology is important for civil engineering as it allows interpretation of physical rock properties like texture and structure. This helps determine rocks' suitability for uses like foundations, tunnels, and construction materials based on their strength and durability. Petrology also provides insight into earth history and aids discovery of mineral resources through understanding rock formation and composition.
Lecture # 02, 03 316 geology and earth quake engineering 5th
The document discusses different types of rocks:
1. Igneous rocks form from cooling magma and include intrusive granitic rocks, extrusive volcanic rocks like basalt, and hypabyssal rocks.
2. Sedimentary rocks form through the lithification of sediments and include clastic rocks like sandstone, chemical rocks like limestone, and organic rocks like coal.
3. Metamorphic rocks form from the alteration of existing rocks under heat, pressure, and fluids, changing their texture and minerals. Foliated rocks include schist and gneiss, while non-foliated rocks include marble and quartzite.
Sedimentary rocks
This document summarizes key information about sedimentary rocks, including their formation processes (mechanical, organic, chemical), structural features (stratification, lamination, cross-bedding), and common types (limestone, sandstone, shale, laterite). Sedimentary rocks form from the deposition and consolidation of sediments and make up 70-80% of the Earth's surface. Their formation involves compaction, cementation, and crystallization. Structural features provide clues to depositional environments. Common types are described along with their compositions and uses.
minerals and rocks
Minerals are found in rocks and there are over 3000 known types of minerals. Minerals have different properties like color, hardness, streak, and luster that can be used to identify them. There are three main types of rocks: igneous rocks which form from cooling magma or lava, sedimentary rocks which form from compressed and cemented sediment, and metamorphic rocks which form from other rocks being subjected to heat and pressure below the earth's surface. Common rocks like granite, shale, and marble are used for construction materials, building monuments, and other purposes due to their unique properties.
Sedimentary Rocks
This document discusses sedimentary rocks, including their formation, classification, and characteristic textures and structures. Sedimentary rocks form through the lithification of sediments deposited under water. They are classified based on their composition into clastic rocks (formed from fragments of pre-existing rocks), chemical/evaporite rocks (formed by chemical precipitation), and organic rocks (containing organic matter). Key textures include grain size, shape, packing, and fabric. Common structures include stratification, lamination, cross-bedding, graded bedding, and ripple marks, which provide information about depositional environments.
SEDIMENTARY ROCK (teach)
Sedimentary rock is formed through the weathering, erosion, and deposition of sediment from rivers and oceans over long periods of time. Layers of sediment are deposited and compressed under pressure from overlying layers, and minerals from seawater cement the sediment particles together into rock. The most common types of sedimentary rock include conglomerate, sandstone, shale, siltstone, and limestone.
Sedimentary Rocks/EPCC/LM5 A
This document discusses different types of sedimentary rocks including clastic sedimentary rocks like breccia, conglomerate, sandstone, siltstone and shale formed from weathered debris. It also discusses chemical sedimentary rocks like limestone, evaporites including rock salt and gypsum, chert and coal. Finally, it mentions several sedimentary structures including cross bedded sandstone, graded bedding, mud cracks, ripple marks and trace fossils.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.
