CRETACEOUS AND PALEOGENE MANGANESE-ENCRUSTED HARDGROUNDS FROM CENTRAL PACIFIC GUYOTS1 David K. Watkins,2 Isabella Premoli Silva,3 and Elisabetta Erba3 ABSTRACT Manganese-encrusted hardgrounds and associated sediments from four guyots in the western Pacific Ocean were investigated using lithostratigraphic and biostratigraphic examination of thin sections. Biostratigraphic data from manganese-encrusted hard- grounds constrain the age of platform drowning to early middle Eocene for Limalok Guyot, latest Maastrichtian to early Paleocene for Wodejebato Guyot, and middle late Albian for MIT Guyot.
