New Data on the Upper Jurassic (Middle–Upper Oxfordian and Middle Volgian) Foraminifers in the East of the Moscow

Аннотация

The Middle–Upper Oxfordian foraminifera were studied from the borehole section drilled in the east of the Moscow Region (Russia). The foraminiferal zones were distinguished in Oxfordian clays: Opthalmidium strumosum–Lenticulina brestica and Lenticulina russiensis–Epistomina uhligi. It was established that the distribution of foraminiferal assemblages varies throughout the Moscow Region.
