Biostratigraphy of Eocene to Oligocene deep-water agglutinated foraminifers in the red clays from Site 767, Celebes Sea
Deep-water agglutinated foraminifers were examined from reddish brown claystones comprising lithologic Unit 4 of Ocean Drilling Program Holes 767B and 767C. The biostratigraphy of deep-water agglutinated foraminifers in this unit indicates an Eocene to Oligocene age. The assemblages are cosmopolitan...
