Abstract

Examination of solvent-extractable lipids in sediments from Beibu Gulf, South China Sea by capillary gas chromatography (GC) and capillary gas chromatography-mass spectrometry (GC-MS) resulted in the first identifications of β, γ-carotanes and their C19 to C31 homologs in the modern sediments from the China Seas. Distributional features of these (mainly triterpenoid and steroid hydrocarbons) biomarkers are discussed and the possibility of using these compounds as indicators of source of materials, diagenesis and depositional conditions is explored. It was found that the biomarkers in this region are mixtures of allochthonous (terrigenous and/or crude oil leak or pollution) and antochthonous (marine) organic components. The biomarders have proved to be of value for understanding sedimentation.
