Late Miocene to Pleistocene planktonic foraminifera of ODP Site 111-677

Forty-three core-catcher samples from the upper Miocene to uppermost Pleistocene of ODP Site 677 were examined for planktonic foraminifers. Range charts were compiled for Holes 677A and 677B, and zonal markers and datum planes are correlated with the most recently published time scale. The absence o...

Description
Summary:Forty-three core-catcher samples from the upper Miocene to uppermost Pleistocene of ODP Site 677 were examined for planktonic foraminifers. Range charts were compiled for Holes 677A and 677B, and zonal markers and datum planes are correlated with the most recently published time scale. The absence of key species such as Globorotalia truncatulinoides, Globorotalia tosaensis, Globorotalia miocenica, and Globorotalia margaritae prohibits the use of any of the standard tropical zonal schemes. The zonal scheme used here was devised for this area on DSDP Leg 9.
