Abstract

Data obtained on the distribution patterns of biomarker hydrocarbons (n-alkanes, isoprenanes, steranes, and terpanes) in oils, organic matter in rocks, prokaryotes, and thermolysis products of the insoluble part of prokaryotic biomass indicate that the relatively high concentration of diasteranes (rearranged steranes) in the organic matter of rocks and in oils generated by clay strata is caused by characteristics of the original organic matter but not by the process of isomerization of regular steranes, as has been previously thought.

石油与岩石有机质中双甾烷的形成

生物标志烃(正构烷烃、异戊二烷、甾烷和萜烷)在油类、岩石有机质、原核生物、原核生物生物量不溶性部分的热裂解产物表明，岩石有机质和粘土地层生成的油中相对高浓度的重排甾烷(重排甾烷)是由原始有机质的特性引起的，而不是像以前认为的那样是由规则甾烷异构化过程引起的。
