Shallow-water skeletal debris and larger foraminifers from Deep Sea Drilling Project Site 462, Nauru Basin, western equatorial Pacific.

Abstract

Shallow-water larger foraminifers and associated forms adapted to a reef environment were recovered from Hole 462 in the Nauru Basin, S of the Marshall Islands. Shallow-water material, mainly reworked, 1) is frequently associated with volcaniclastic breccias to coarse sands, 2) occurs episodicaly intebedded within a turbiditic sequence whose clasts are pelagic components. More than 60 species of larger foraminifers were identified, and most of them are age-diagnostic, ranging in age from Campanian to late Oligocene. A comparison was made with similar shallow-water assemblages in the central western Pacific (Line Islands). -from Authors
