Bound lipids in lacustrine sediments in Guchenghu Lake, East China

摘要

BIOMARKERS used as indicators of the paleoclimatic and paleoenvironmental changes are re-quired to be bio-specific in origin and be stable in the early diagenesis process. The input ofplenty of land-derived organics, as well as possible changes in the early diagenesis process,made the lipid composition of inland lacustrine sediments more complicated, and, as a result,the bio-indicating significance of some biomarkers often become obscured. Except for
