Northern Pacific Lutetian in Kamchatka

The Paleogene section of the Il’pinskii Peninsula in northeastern Kamchatka is a reference section for the North Pacific rim. The marine sedimentary succession, 2500m-thick and ranging from the Paleocene to Oligocene, forms one of the northernmost Paleogene sections in the Pacific to yield Paleogene calcareous plankton. Several studies have been dedicated to the study of […]
