Preliminary lipid analyses of cores 14, 18 and 28 from Deep Sea Drilling Project Hole 416A ( organic geochemistry).

Abstract

The solvent-extractable lipids from the Valanginian turbidite sequence include n-alanes, n-alkanoic acids, acyclic isoprenoid alkanes, steranes, rearranged sterenes, 4-methyl-rearranged sterenes, triterpanes, triterpenes, aromatic hydrocarbons and porphyrins. The distributions of these compounds suggest fairly uniform contributions from terrigenous, algal and bacterial sources and also show that the sediments are at an immature stage of diagenesis.- from Authors
