摘要
:固体地球化学中常用的Pb Pb和Rb Sr同位素方法被用于测定石油生成、运移的年龄。对准噶尔盆地乌尔禾沥青脉、塔里木盆地志留系固体沥青的Pb Pb和Rb Sr同位素年龄测定表明 ,油气生成、运移均与重大地质事件有关 ,这种方法可以用来测定石油生成、运移的年龄 ,从而解决了石油生成机制、运移动力等研究难题。
The Pb Pb and Rb Sr isotopic dating methods commonly used in solid geochemistry are applied to date generation and migration of petroleum. Pb Pb and Rb Sr isotopic dating of solid bitumen in Xinjiang area shows that Pb Pb and Rb Sr isotopic dating is a potential method for dating petroleum generation and migration. The dating results show that petroleum generation and migration are related to the significant geologic events. Some mechanisms of petroleum generation and migration can be solved according to Pb Pb and Rb Sr isotopic data.
