The Carbon and Oxygen Isotope Composition of Secondary Carbonates in Volcanites of the pre-Jurassic Complex of the West Siberian Plate

Moscow University Geology Bulletin, 2019
The carbon and oxygen isotope composition of secondary carbonates from acidic effusives in the top of the pre-Jurassic complex of the West Siberian plate (Tomsk Region) was studied. The siderite values of δ13С (VPDB) and δ18О (VSMOW) vary from –6.6 to –2.4‰ and from 7.8 to 12.3‰, while the calcite values vary from –8.9 to –8.4‰ and from 2.5 to 3.7 ...

Epigenetic Alterations of Felsic Volcanites from the Top of the pre-Jurassic Complex in the Southeastern Part of the West Siberian Plate

Moscow University Geology Bulletin, 2019
A study of secondary alterations of felsic effusives with reservoir properties from the top of the West Siberian pre-Jurassic complex (Tomsk Region) was performed. The lithological, petrographic, and mineralogical features of these rocks indicate their alterations by low-temperature hydrothermal solutions, while the weathering products that are ...

Structure and Potential Oil and Gas Reserves of the Pre-Jurassic (Transitional) Complex of the Southeastern Part of West Siberia

Energy Sources, 2001
There are several different theories for the mechanism of development of pre-Jurassic sequences in Western Siberia. Many geologists believe that Hercynian-Caledonian and Bayikalian orogenies of the Paleozoic age affected all pre-Jurassic deposits. Others assume that pre-Jurassic?Paleozoic sediments were formed in the Paleo-Asian ocean that existed in ...

Complex lithological and geochemical characteristics of the main material complexes of the pre-Jurassic base of the Uvatsky NGR

Нефтяная провинция, 2022
В составе доюрского комплекса Западной Сибири внимание геологов-нефтяников давно привлекают породы, которые могут быть нетрадиционными коллекторами углеводородов. В результате комплексных лабораторных исследований за период 2016 - 2022 годы получены новые оригинальные данные, обзор которых приводится в настоящей работе.
