Preliminary organic geochemistry of laminated versus nonlaminated sediments from Holes 479 and 480, Deep Sea Drilling Project Leg 64.

Abstract

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.-Author
