SCIENTIST SOFIA VASYLIVNA ROZUMEIKO (ON THE 90TH ANNIVERSARY OF HER BIRTH)

Abstract

The article is dedicated to the 90th anniversary of the birth of Sofia Vasylivna Rozumeyko, a famous scientist in paleontology and stratigraphy of the Upper Cretaceous of Volyn-Podillia and the Cretaceous-Neogene of the Carpathian region.Sofia Rozumeyko (Gren) studied at the Faculty of Geology and Exploration of the Lviv Polytechnic Institute. In 1957 she received a diploma of a engineer-geologist, worked for two years at the Kosiv gas field. In 1959 she got a job at the Institute of Geology of Combustible Minerals in Lviv (the modern name of the institution is the Institute of Geology and Geochemistry of Combustible Minerals of the National Academy of Sciences of Ukraine). She worked as a collector in the department of tectonics and stratigraphy, later in the group of scientific and technical information, where in the period from 1964 to 1974 she received the position of senior engineer, and later – junior research. In 1974, S.V. Rozumeiko was transferred to the laboratory of biostratigraphy. In 1981, the laboratory was attached to the department of paleogeography and tectonics of combustible mineral provinces, in which Sofya Vasylivna worked until the end of her professional career in 1993.In 1966, S.V. Rozumeiko entered the correspondence postgraduate course at the Department of Mesozoic Stratigraphy of the Institute of Geological Sciences of the Academy of Sciences of the Ukrainian SSR, and in 1973 she defended her thesis “Facial distribution of Upper Cretaceous foraminifers of the Volyn-Podillia Plate” and received the degree of Candidate of Geological and Mineralogical Sciences.The scientific legacy of Sofia Vasylivna includes approximately 40 works, among them two personal monographs. In the Upper Cretaceous deposits of the southwest of the East European Platform, S.V. Rozumeiko identified 13 biostratigraphic zones for foraminifers and 28 foraminiferal complexes (paleocoenoses), which correspond to lithofacies varieties of rocks. From these same deposits, she monographically described more than 90 species of foraminifers, which mainly belong to the families Ataxophragmiidae, Nodosariidae, Discorbidae, Gavelinellidae, Buliminidae, Bolivinidae. She studied the distribution of foraminifera in the Cretaceous–Neogene deposits of the Carpathian region. S.V. Rozumeiko became a co-author of the Regional Scheme of Cretaceous Deposits of Platform Ukraine.
