Epigenetic changes of acidic volcanites from the top of the Western Siberia Pre-Jurassic complex

Moscow University Bulletin. Series 4. Geology, 2019
The study of secondary changes of acidic effusives with reservoir properties from the top of the Western Siberia pre-Jurassic complex (Tomsk Region) was produced. Lithological, petrographic and mineralogical features of these rocks indicate their change by low-temperature hydrothermal solutions, while weathering products, which are widely spread at the

Subduction complex of pre-Jurassic age, northern Anatolia, Turkey

Geology, 1981
In northern Anatolia a zone of pre-Liassic orogenic deformation is located mainly between the internal Anatolian massifs and the North Anatolian fault. This belt consists of metamorphic rocks in blueschist, greenschist, and amphibolite facies and an ophiolitic, dynamometa-morphic melange.

C and O isotope composition of secondary carbonates in the volcanites of the pre-Jurassic complex of the Western-Siberian Plate

Moscow University Bulletin. Series 4. Geology, 2019
The carbon and oxygen isotopic composition of secondary carbonates from acidic effusives fro investigated. Ϭ13С (VPDB) and Ϭ18О (VSMOW) values of siderite vary from –6,6 to –2,4‰ m the top of the Western Siberia pre-Jurassic complex (Tomsk Region) was and from 7,8 to 12,3‰, while Ϭ13С and Ϭ18О values of calcite vary from –8,9 to –8,4‰ and from 2,5 to 3,

REGIONAL PATTERNS OF OIL AND GAS POTENTIAL OF THE PRE-JURASSIC COMPLEX ON THE EXAMPLE OF THE TOMSK REGION AND THE KHANTY-MANSI AUTONOMOUS DISTRICT

ГЕОФИЗИКА, 2022
В статье рассмотрены данные по нефтегазоносности пород доюрского комплекса (ДЮК) в пределах Томской области и Ханты-Мансийского автономного округа. Проведенный анализ позволил выявить ряд закономерностей расположения залежей углеводородов в зависимости от структурно-тектонического положения, а также вещественного состава коренных пород, слагающих ...

Guidelines for assessing the provenance of Mesozoic and Cenozoic clastic successions sourced by pre-Jurassic basement complexes in southernmost North America

Journal of Sedimentary Research, 2020
ABSTRACT Mexico is an attractive place for provenance studies focused on reconstructing the tectonic evolution of North America. This is because Mexico hosts a well-preserved clastic record associated with some of the major Mesozoic and Cenozoic tectonic processes that shaped the face of this continent.

Geological Structure of The Pre-Jurassic Complex Within The Elizarovsky Trough of The Frolov Megadepression and The Galyanovsky Nose of The Krasnoleninsky Arch According to Seismic Data CDP 3D

Tyumen 2021, 2021
Summary The generation of terrigenous super reservoirs is not always determined by the primary sedimentation conditions and the quality of sand material; often reservoirs with good reservoir properties are formed during diagenetic changes in rocks. Reconstruction of diagenetic processes and superimposed changes in sedimentary material, leading, in the ...

Seismogeological analysis of the pre-Jurassic sediment complexes of the South Kara syneclise in connection with the tectonic zoning of the sedimentary cover

Russian Geology and Geophysics, 2014
Abstract We present new data on the structure of deep horizons of the sedimentary cover of the South Kara syneclise, based on an integrated interpretation of data from modern seismic prospecting and data on the geologic structure of the adjacent folded areas. A network of seismic base profiles reprocessed with up-to-date programs is used

APPLICATION OF AVO ANALYSIS FOR HIGHLIGHTING OF COAL LAYER OF EARLY JURASSIC DEPOSITS OF WESTERN SIBERIA IN THE STUDY OF THE WEATHERING CRUST OF THE PRE-JURASSIC COMPLEX

ГЕОФИЗИКА, 2022
В статье рассмотрены подходы AVO-анализа для прогноза угольных пластов в нижнеюрских отложениях. Проведено моделирование AVO-атрибутов на основе реальных данных по нескольким скважинам по псевдолинии 2D. Анализ кроссплотов AVO-атрибутов (интерсепт/градиент) позволил выделить в разрезе AVO-аномалии 4-го класса, которые соответствуют угольным пластам ...

JOINT ANALYSIS OF AZIMUTHAL ATTRIBUTES AND DIFFRACTION ENERGY FOR PREDICTING PERSPECTIVES IN THE PRE-JURASSIC COMPLEX WITHIN NYUROL STRUCTURAL FACIAL ZONE OF WESTERN SIBERIA

ГЕОФИЗИКА, 2023
В статье рассмотрены подходы к прогнозу перспектив нефтегазоносности в интервале доюрского комплекса в пределах Нюроль- ской структурно-фациальной зоны Западной Сибири. Поскольку фундамент преимущественно представлен плотными породами с непроницаемой матрицей, то перспективы интервала связаны в первую очередь с выделением областей повышеннои ...
