The Mesozoic ophiolites of the Alps: a review

open access: yes, 1994
The Alpine ophiolites are mostly concentrated in the inner and axial sectors of the Penninic nappe pile, as slices of the Jurassic Tethyan ocean which opened between the Europe and Adria (Africa) passive margins.

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.

Geochemical Characteristics of a Pre-Middle Jurassic Oceanic Crust Fragment From the Central Pontides in Northern Turkey: Geodynamic Implications on Intra-Oceanic Subduction Initiation

Chemie Der Erde, 2020
The Central Pontides (northern Turkey) is one of the key localities to understand the geodynamic evolution of the Palaeo- and Neotethyan oceans. It consists of the pre-Jurassic basement units, the Early Jurassic and the Early Cretaceous accretionary ...

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.

Geochemical Evidence Used to Test Alternative Plate Tectonic Models for Pre-Upper Jurassic (Palaeotethyan) Units in the Central Pontides, N Turkey

open access: yesGeological Journal, 1999
Ease-west trending, inferred Palaeotethyan subduction-accretion complexes form much of the pre-Upper Jurassic basement of the Central Pontides. A number of specific tectonic units are present that include variably metamorphosed basic igneous rocks, as ...

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 ...
