Inorganic chemical composition and downhole variation of major and trace elements yields useful insights into the sediment provenance and paleoceanography of deep-sea sediments of deepwater continental margins. Here, fine-grained sediments were chemically analyzed at ~10-m intervals from the Eocene to Albian section at Site 1276. These sediments represent a time when background hemipelagic sedimentation was continuously beneath, or near, the calcite compensation depth (CCD). Additional samples were analyzed from the upper Paleocene-middle Eocene time interval to determine whether a volcaniclastic component is present, as suggested by petrographic studies of the coarser size fraction. Sediments recovered near the bottom of the hole show the effects of contact metamorphism adjacent to a sill of alkaline basalt. The overlying thick (~700 m) Albian succession (lithologic Unit 5) is indicative of a dominantly terrigenous source. Redox-sensitive trace elements (e.g., Cu, Ni, V, and Cr) are concentrated in organic-rich layers (black shales) that can be partially correlated with oceanic anoxic Events 1a-1d and 2.
