Stratigraphy and Sedimentogenesis of the Clinoform Upper Jurassic of the Anabar–Lena Sedimentary Basin (Arctic Siberia, Laptev Sea Coast)
Abstract —New materials on the stratigraphy and structural features of the Bathonian–Neocomian sections of the Anabar–Lena basin are presented. In the territory adjacent to the Taimyr mountain-folded system, a clinoform-like structure of the Upper Jurassic strata has been revealed, which are characterized by high thickness compared to adjacent sections in the east of this region. The lectostratotype of the Chernokhrebetnaya Formation (uppermost Lower Oxfordian–lowermost Volgian) is proposed. The most complete and continuous stratigraphic section is compiled, its litho- and chronostratigraphic correlations are given comparing to the sections of adjacent territories characterized in detail by fossil assamblages. The evidences for a new lithostratigraphic division of the territory are provided, facies zoning of sediments is clarified, a thickness chart of the Upper Bathonian–Boreal Berriasian strata of the Khatanga–Olenek interfluve is proposed.
期刊介绍:
The journal publishes original reports of theoretical and methodological nature in the fields of geology, geophysics, and geochemistry, which contain data on composition and structure of the Earth''s crust and mantle, describes processes of formation and general regularities of commercial mineral occurrences, investigations on development and application of geological-geophysical methods for their revealing. As to works of regional nature, accelerated publication are available for original papers on a variety of problems of comparative geology taking into account specific character of Siberia, adjacent Asian countries and water areas. The journal will also publish reviews, critical articles, chronicle of the most important scientific events, and advertisements.
