| Abstract: | Carbon isotopic compositions of individual n-alkanols and sterols in modern sediments from the Nansha Islands sea area are
measured after derivatization to trimethylsilyl ethers by the new isotopic analytical technique of GC/C/IRMS. The effects
of the three added silyl carbon atoms in every alcohol molecule on these compound isotopic compositions and the characteristics
of their carbon isotopic compositions are studied. Then their biological sources are discussed using their carbon isotopic
compositions.
