Two holes were drilled in what appeared to be a faulted terrace on Yömei, a small seamount north of Nintoku Seamount, in the Emperor Seamount chain. In Hole 431 we cored the interval 0 to 95 meters twice, and recovered a total of 3.33 meters of sand and centimetersized unconsolidated gravel. This material is composed of 90 per cent angular iron-manganese fragments and 10 per cent rounded pebbles, sponge fragments, foraminifers, and authigenic silicates. The pebbles are extremely heterogeneous, and include andesites, dacites, granites, schists, and
Two holes were drilled in what appeared to be perched terrace deposits atop Nintoku Seamount. Section 1-4 encompasses the Eocene/Pliocene hiatus. In Hole 432 we cored the interval 0 to 5.5 meters, and recovered 3 meters of light green unconsolidated pelagic sediments. The sand-sized fraction consists principally of Quaternary planktonic foraminifers deposited above the CCD. The
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
