Summary: Sedimentologic, mineralogic, and geochemical analyses were performed on samples from Hole U1317A drilled on Challenger Mound during Integrated Ocean Drilling Program Expedition 307. Challenger Mound consists entirely of sediments bearing well-preserved coldwater coral Lophelia pertusa and other various bioclasts (planktonic foraminifers, cocolithophorids, echinoderms, sponge spicules, etc.) and containing large amounts of clays and quartz. Bioerosion of corals played an important role in generating carbonate grains. The biogenic fraction is autochthonous, whereas the siliciclastic fraction (dominated by illite and kaolinite-chlorite) is clearly allochthonous. Organic matter content is low, and no organic matter of bacterial origin was recognized. Challenger Mound is composed of a mixture of skeletal and siliciclastic components.
