Mesozoic calcareous- nannoplankton stratigraphy of the central North Pacific Mountains and Hess Rise. Deep Sea Drilling Project Leg 62 ( DSDP).

Abstract

Cretaceous sediments were recovered at all four sites (Sites 463-466) of the central North Pacific drilled during Leg 62 of the DSDP. One of the objectives was to get more information about the development of ocean plankton communities and early evolution of planktonic groups of the Mesozoic. In this article, the Cretaceous calcareous nannofossils from two areas of the central North Pacific (Mid-Pacific Mountains and Hess Rise) are listed and discussed. -from Author
