Precambrian group

Precambrian group lead by V.N.Puchkov.

Sergeeva Nina Dmitrievna

Joined the Institute: 1971.

Current professional position: Senior Researcher

Education: Bashkirian State University, Department of Geography, and Voronezh State University, Faculty of Geology (1980).

PhD: Geology and Mineralogy Dissertation defended in 1989, entitled: «Mineralogical correlation of the Upper Precambrian deposits of the Southern Urals»

Scientific interests: studies of general and regional geology, mineralogy, geochemistry and stratigraphy of the Upper Precambrian deposits and magmatic complexes of the Southern Urals and the East of the East European platform with the aim of refining the geology of the Precambrian deposits of the Region and detalization of regional stratigraphic schemes, aimed to a refining of the General stratigraphic scheme of the Precambrian of Russia.

Ratov Alexandr Alexandrovich

Joined the Institute: 2013.

Current professional position: Junior researcher.

Education: Bashkirian State University (2013).

Scientific activity connected with studies in the field of geotectonics, regional geology, mineralogy and geochemistry of the Upper Precambrian magmatic rocks of the Southern Urals and the East of the of the Russian platform with the aim of their correlation, and definition of the geodynamic conditions of their origin.

Kozlova Olga Vyacheslavovna

Joined the Institute: 2011.

Current professional position: Engineer-researcher.

Education: Bashkirian State University (1987), Department of Geography.

She studies the mineralogy of terrigenous deposits of the Riphean and Vendian of the Southern Urals and adjacent areas of the East European platform, with the aim of their correlation using accessory minerals.
