(Table 1) Sample descriptions and geochemistry for core material at DSDP Holes 64-479 and 64-480

Laminated and nonlaminated sediments from Holes 480 and 479 have been analyzed for potential differences in the composition of organic matter. Their lipid composition is very similar and indicates a primary autochthonous microbial origin and some influx of allochthonous higher-plant detritus. The nonlaminated sections contain relatively more terrigenous plant wax detritus versus autochthonous residues and a much greater amount of perylene than the laminated sections.
