New data on Upper Cretaceous stratigraphy and the discovery of the marine Paleogene on the eastern Chukotka Peninsula (based on foraminifers’ studies)
Abstract
In the area of Sheet Q-1-XXI, XXII of the Geological Map, the Late Cretaceous age of the Amgenʾ strata and Leurvaam Formation have been confirmed based on foraminifers’ findings. For the first time, Paleogene deposits with the remains of planktonic foraminifers were found on the Chukotka Peninsula. The discovery of this marine fauna helps our better understanding of the geological history of the region and allows amendments in paleogeographic reconstructions.
