Abstract:
Purpose. It is based on investigation of regularities of distribution patterns of black shales in space and time in sections of the Late Proterozoic of the Transdniestria for further investigating by lithological, mineralogical, petrographical and geochemical analysis.
Methodology. It consists of field working in outcrops of the Vendian section and their detailed lithological description, facies analysis, petrographical and lithology-geochemical investigations.
Findings. A revision of the Late Proterozoic sediment section of the Transdniestrian Podillia was done; conditions of stratification and under- and overburden contacts of layers were updated; textural, structural and other features of stratigraphic layers which indicate genetic and facial aspects of their formation were determined. In the deposits of Mohyliv-Podilskyi range of the Vendian five stratigraphic levels which contain black shale were allocated: lomozivski, liadavski, bronnytski, zinkivski and kaliuski layers. Also new strata of the Ediacaran biota which will be described in detail in the following publications were found.
Originality. For the first time, for Mohyliv-Podilskyi range of the Transdniestria five stratigraphic grades of black shale accumulation were distinguished. Black shales precipitated in uncompensated depressions of an epicontinental basin and were concentrated with a lot of organic matter. They could be considered as petroleum source rocks of the Precambrian and Early Paleozoic sedimentary formations of the Volyn-Podillia.
Practical value. It is based on using the data for predicting works within the Volyn-Podillia plate related to the petroleum potential areas.
