DEBRIS SOURCE AREA EVOLUTION DURING FORMATION OF THE URALIAN FOREDEEP AT THE SAKMARIAN STAGE OF THE EARLY PERMIAN ACCORDING TO U-Pb LA-ICP-MS ISOTOPE DATING OF DETRITAL ZIRCONS

open access: yesГеодинамика и тектонофизика
The article presents the results of studying the sources of terrigenous material deposition in the Uralian foredeep according to U-Pb dating of detrital zircons from terrigenous rocks of four stratigraphic levels of the Kapysov formation (Sakmarian stage)

The albian-cenomanian boudary in the northern part of the Don-Medveditsa dislocations. Paper 1. The history of studying and the section descriptions [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Серия Науки о Земле
The Albian-Cenomanian rocks compose a single complex of terrigenous deposits over the Volga Region. Delineation of the boundaries of the Cretaceous system units generally tends to cause difficulties, accounted for by rare finds of the fossils.
