Curriculum vitae
Popov Sergey Valentinovich was born 04.06.1945 in Moscow. In 1967 graduated from Department of Geology of Moscow State University. Since 1967 have been working at the Paleontological Institute AS USSR (later – Russian AS). In 1974 got the degree Candidate of Biological Sciences (PhD) and in 1990 the degree Doctor of Geol.-Mineralogical Sciences. Since 1995 to 1998 - head of Mollusc’ laboratory of the Paleontological Institute RAS. Now – main scientific worker of the same Institute.
The main field of scientific interests is taxonomy of Bivalvia and the Paleogene - Neogene biostratigraphy, paleogeography and zoogeography of the Paratethys. The author of 200 publications, including 15 monographs (3 personal and 5 in which he is first author). Member of Paleogene and Neogene commissions of the Interdepartment Stratigraphic Committee RF. Head of 45 field research groups worked in the Former Soviet Union: Georgia, Kazakhstan, Pre-Caucasus, the Ukraine, Turkmenia, Volga-Don and Far East of Russia, besides in Greece, Poland, Sicily and Iran.
He was leader of paleogeographic working group on FSU territory in International "Peri-Tethys Prоgramme", participant of Project 174 IGCP "Geological events at the Eocene - Oligocene boundary", active member of the Project 326 "Oligocene - Miocene transition in the Northern hemisphere" and Project 343 "Stratigraphical correlation of epicontinental Peri-Tethian basins", Russian coordinator and head of maping group in the Project 329 "Neogene of the Paratethys" and in EEDEN International Programm. Coordinator in bilateral international projects with Poland, Hungary and Italy.

Seismic data allows watching the major discontinuities in deposition in result of water level downfalls and tectonic reasons, which are followed as in shalves, as in deepwater depressions. At least three erosional phases ranging from Paleogene to Pontian time: at the terminal Eocene, terminal Maykopian, and at the Sarmatian – Maeotian boundary. Moreover, intra-Pontian erosional surface is clearly identified.
The Eastern Paratethys stratigraphic scale stability during more then 100 years is determined by boundaries, which correlate with tectonic and lithologic-facial reorganizations and main water level downfalls and reflect not only paleontological events. Units, which based on faunistic data mainly, often are not well distinct out of stratotypic area and facial zone. We have these problems with units of the Maykopian second part (Upper Oligocene – Lower Miocene), late Chokrakian – Karaganian and Maeotian – Pontian boundaries.

The type section of the Oligocene to Lower Miocene Maikop Group, considered the main source rock in the Eastern Paratethys, has been studied using geochemical proxies to gain insights into depositional setting and hydrocarbon potential.
The Maikop Group at the type section is about 600 m [2000 ft.] thick. Deposition commenced after a major Late Eocene sea level drop and a subsequent Early Oligocene sea level rise. The Maikop Group is composed mainly of carbonate-free pelitic rocks. Calcareous rocks are limited to the Lower Oligocene Pshekha Formation, the Polbian Bed forming a basin-wide marker horizon deposited during a time with significantly decreased salinity (“Solenovian event”), and the Upper Morozkina Balka Formation. Anoxic conditions prevailed and were interrupted for longer times only during deposition of the lower part of the Pshekha Formation, the Polbian Bed and the Lower Miocene Olginskaya Formation.
TOC contents range up to 3.5 wt.%. HI values are typically below 300 mgHC/gTOC, but reach 420 mgHC/gTOC in black shales overlying the Polbian Bed (Lower Morozkina Balka Fm.). Organic richness of this level, about 10 m [33 ft.] thick, is controlled by low salinity and high bioproductivity.
The Maikop Group could generate approximately 2.0 t HC/m² surface area. A significant part (0.45 t/m²) comes from the Lower Morozkina Balka Formation, which generates a paraffinic-naphthenic-aromatic mixed oil with high wax and low sulphur contents. The Pshekha, Upper Morozkina Balka and Batalpashinsk formations would generate low-wax oil or condensate. The hydrocarbon generation potential of the overlying formations is minor.
