The document discusses a proposed geological study of the Chukotka Peninsula region in northeastern Russia. The study would have three main objectives: 1) compile existing geological and geophysical data from the region into a unified database, 2) conduct modern analytical studies of rock samples, focusing on apatite fission track analysis to determine the cooling history, and 3) develop a tectonic and sedimentary evolution model for the study area. The study would be carried out over 12 months and include an intermediate report at 6 months and a final report at completion. Additional fieldwork is proposed to collect more samples from the South Anyui suture zone.

Research Objectives
The study area is located in the northeastern Asia and consists of the
Late Mesozoic Chukotka Fold-and-Thrust Belt, which is believed to
be formed as a result Mesozoic convergence, and following collision
of the Arctic Alaska-Chukchi Microplate (AACM) with the Omolon-
Siberian margin in the course of the Canada oceanic basin formation.
The deformed rocks are overlain by Aptian-Albian sedimentary
successions and the Late Cretaceous Okhotsk-Chukotka Volcanic Belt
(Fig. 1). Most of these tectonic units extend further north to form a
basement of the offshore South Chukchi Sedimentary Basin filled in
with the uppermost Lower Cretaceous and younger rocks.
During the past decade, numerous geological and geophysical
studies were carried out in this region by Russian and international
research teams, including structural, lithostratigraphic, U-Pb dating
of intrusions and detrital zircons, and zircon fission track studies
of sedimentary rocks, as well as chemical and isotopic dating of
magmatic rocks. The available data can be used to shed more light
on the AACM formation and evolution. However, the important data
on the post-collisional Late Cretaceous and Cenozoic evolution of the
study area are still missing, and so the geological history of the large
South Chukchi and North Chukchi sedimentary basins cannot be fully
understood.

CHUKOTKA PENINSULA
Research Objectives
The main goals of the project are:
ƒƒ To produce comprehensive compilation of the existing
geological, geophysical and geochemical data over Chukotka
region of NE Russia, and adjacent AACM areas of Alaska to
combine them in the unique database;
ƒƒ To accomplish modern analytical studies of the rocks from the
key localities using state-of-art methods. The main attention
will be paid to the apatite fission track analysis of Paleozoic and
Mesozoic rocks to identify and quantify the most recent cooling/
uplift/erosion history that will help to unravel evolution of
adjacent offshore sedimentary basins. However, key samples for
understanding evolution of the Chukotka Peninsula and adjacent
areas will be studied by other methods (U-Pb detrital zircon
dating, mineralogical, chemical, RockEval, etc. studies) as well;
ƒƒ To produce a model of tectonic and sedimentary evolution of
the study area with reference to events that may be recognized
in the South- and North Chukchi sedimentary basins and their
basement
Deliverables
Intermediate and final reports will be presented.
The Intermediate Report will be presented in 6 months after signing
of the Licensing Agreement. It contains Tectono-stratigraphic
correlation charts based on available data from papers and open-file
reports, location map, data of available laboratory studies, and short
explanation text.
The Final Report will contain a tectonic overview of the study area,
litho-stratigraphy of the Neoproterozoic to Cenozoic sedimentary
successions, characterization of the tectonic and depositional
events, structural styles, paleogeography, correlation of the
tectonostratigraphy of the Chukotka with adjacent Alaska and
Wrangel Island. The laboratory analytical studies will be focused on
the apatite fission track analysis, but will also include mineralogical
analysis of heavy minerals, detrital zircon geochronology, zircon fission
track analysis, non-organic isotopic chemical analyses, RockEval
analysis and vitrinite reflectance measurements. The Report will be
accompanied with an ArcGIS database, and a series of enclosures,
such as tectonostratigraphic charts, cross-sections, geologic and
paleogeographic maps, etc.
Data Sources
ƒƒ The numerous Russian papers and the open-file geological
reports as well as international papers and USGS reports on
geology of the AACM
ƒƒ Geological data collected by the project team during last 15
years on Chukotka Peninsula and Wrangel Island and not
published yet including both field observations and laboratory
studies
ƒƒ Approximately 100 samples (see location in Fig. 1), and hundreds
of thin sections of predominantly Mesozoic rocks from Chukotka
Fold-and-Thrust Belt, Okhotsk-Chukotka Volcanic Belt, South
Anyui Suture Zone, and Wrangel Island available for the
research team
Timing and Cost
ƒƒ Published and open-file reports data compilation, and the
Intermediate report after 6 months
ƒƒ Analytical studies, data compilation, and the Final Report

SOUTH ANYUI SUTURE ZONE
Research Objectives
The South Anyui suture zone contains record of collisional processes
occurred on the southwestern margin of the AACM and likely is the
youngest tectonic unit in the basement of the Chukotka and East
Siberian seas. Its cooling/uplift/erosion most likely was accompanied,
at least partly, by transport and sedimentation of erosion products
in the South Chukchi sedimentary basin. Study of its cooling/uplift/
erosion history will supply with data that help to understand early
stages of the South Chukchi sedimentary basin formation.
Although some samples from the South-Anyui suture zone area are
available and will be studied as a part of the CHUKOTKA PENINSULA
AND SURROUNDING AREAS: A REGIONAL GEOLOGICAL STUDY
project, their number is small and is sufficient for only
reconnaissance study.
Therefore, fieldtrip-2014 to the South Anyui suture zone and adjacent
overlapping sedimentary basins is suggested to verify their Mesozoic
history and to expand samples collection.
A new set of samples from key areas for thin section, mineralogical,
detrital zircon age distribution, apatite and zircon fission track, non-
organic isotopic chemical, RockEval and vitrinite reflection studies
will be collected. Although the main targets of field study are clastic
rocks, a few syn- and post-tectonic intrusions may be studied to
identify age and composition of possible provenance of clastic rocks in
the adjacent onshore and offshore sedimentary basins. Location of the
field study area is shown in Figure 2.
The proposed option is a continuation of the project “CHUKOTKA
PENINSULA AND SURROUNDING AREAS: A REGIONAL GEOLOGICAL
STUDY” and may partly overlap with it in time, but cannot be done
separately from it.
