关于TM/TS指标的意义及应用 总被引:1,自引:0,他引:1
The TM/TS index as the ratio of two isomeric peaks of C27H46 trinurhopane in the m/e 191 fragmentogram is one of the important molecular parameters for petroIeum geochemistry, which has found xcide application in identifying the degree of maturation of organic matter in China. It has been observed that the TM/TS index not only depends on the burial depth and temperature with respect to terrestrial crude oils and source rocks(i.e., it decreases with increasing burial depth and temperature), but also on the type of organic matter and sedimentary facies. So the application of the index indicative of maturation of organic matter is conditional. 相似文献
