| 摘 要： | 应用气相色谱、色谱质谱等分析方法,对鸡西盆地早白垩世烃源岩生物标志化合物特征进行了讨论,揭示了生物标志化合物对该区有机质生物来源、成熟度及沉积环境的指示意义。有机质热演化已进入成熟阶段,且煤岩热演化程度略高于泥岩。泥岩有机质母质来源主要为水生生物,同时有高等生物的输入;煤岩以陆生高等植物输入为主,同时也有水生生物输入。煤岩沉积环境为弱氧化环境,经历过较强的降解作用过程;泥岩沉积环境为还原环境,沉积介质咸化程度较高,更有利于有机质的保存和转化。

| Abstract: | By GC and GC-MS analyses the biomarker characteristics of the early Cretaceous source rocks in the Jixi Basin are discussed.Some typical biomarkers can be used to determine the biologic source nature of the organic material,its maturity and depositional environment.It can be seen that the thermal evolution of the samples have reached maturation stage,and the thermal evolution of the coals is higher than the mud rocks.The mud rocks are mainly from aquatic organisms with high-grade biology input.The coals are mainly from terrigenous with abundant aquatic organisms input.In the area the coals are formed in weak oxidizing environment.The mud rocks deposited in reducing environment with more saline water,it is better for retention and invert of organic material. |
