| 摘 要： | 本文报道了爱丝湖沉积物中烃类的分布特征。经分析鉴定,该湖沉积物中烃类分布主要包括正构烷、烯烃,环状和非环状异戊二烯烃等。这些烃的来源可归属于两种即藻类和细菌,其中来源于细菌的有:植烷、2,6,10,15,19-五甲基二十烷、角鲨烷、蕨烯-7、12-新藿烯和22(29)-藿烯等。来源于藻类的有:甾烯、C_(15)、C_(17)和C_(19)正构烷烃、长链C_(29)二烯和姥鲛烷等。研究表明某些典型的烃类可能出自藻种和菌种,从而进一步说明爱丝湖的沉积环境变化。

| Abstract: | Major constituents were identified as n-alkanes, alkenes, acyclic and cyclic isoprenoid hydrocarbons, triterpenoids and sterenes.Those hydrocarbons were belonged to two sources of algea and bacteria, and source of bacteria contained phytane; 2, 6, 10, 15, 19-pentamethyleicosane; squalene; fern-7-ene; hop-22 (29) -ene and weohop-12-ene, algea source contained sterenes; n-alkanes (C15, C17, C19); C29 diene and pristane. The source possibility of classes of bacteria and algea probably indicated the change of depositional environment in the Ace Lake. |
