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.
Sediment depth is given in mbsf. All samples are late Quaternary. Empty cells = not determined.
