Abstract

This paper presents the microfaunal assemblages of lower Sarmatian (Volhynian) deposits intercepted by 10 hydrocarbon wells from the Blejești hydrocarbon field, S Romania. The identified microfaunas are typically for two Volhynian foraminifera zones: Varidentella reussi Zone and Elphidium reginum Zone. At the contact with the underlying Cretaceous or Middle Miocene (= Badenian) units, the Sarmatian studied samples, containing foraminiferal assemblages with abundant Ammonia beccarri, may not be assigned to a certain biozone. Besides, the identified ostracod assemblages were assigned to the NO 11 Cytheridea hungarica – Aurila mehesi. The composition and the abundance of microfaunal assemblages allow us to advance paleoecological considerations for the lower Sarmatian deposition interval of the studied area.
