| 摘 要： | 我国下古生界海相碳酸盐岩中有机质由于形成时间早，经历了漫长的地质历史演化，一部分有机质深埋已形成了烃类，由于后期构造运动抬升则停止了生烃过程，但当再次深埋时，源岩干酪根受热温度超过一次生烃温度时，源岩又开始第二次生烃。本文对我国古老的下古生界海相碳酸盐岩的二次生烃作用及其机理进行了较为详尽的研究。

| Abstract: | Organic matter in the Lower Palaeozoic marine carbonate rocks has undergone a long-term geological evolution. Part of the organic matter has turned into hydrocarbon by deep burial metamorphism.The progress of hydrocarbon generation is caused by late tectonic rifting. When organic matter is deeply buried for second time and the kerogen is subjected to higher temperature than the formr, the secondry hydrocbon generation will come into being and its mechanism is elaborated of the Lower Palaeozoic marine carbonate rocks. |
