Abstract: The aromatic hydrocarbon fraction of 4 Quaternary cores from Chaidamu Basin was analysed by GC一MS. As a result,a series of long chain fatty acid ethyl esters(C15一C34 ) were first found.Their mass spectrum characteristics are that base peak is m/z 88 and characteristic ion is m/z 101、157,M+,M+一43. These ion existence were confirmed by fragmenting analyses of fatty acid ethyl esters. Distribution of the carbon number of fatty acid ethyl esters in studied samples is from C15 to C34 maximizing at C28 with a strong even to odd carbon number preference. we believe occurrence of fatty acid ethyl esters in studied samples may be related to biochemical process. Fatty acid ethyl esters of Quaternary sediments in Chaidamu Basin may play an important part in formation of biogas in this region.
