| 摘 要： | 通过对三江盆地富锦隆起金山村附近实测剖面的岩石组合、古生物化石及元素地球化学分析,对该地区珍子山组沉积环境进行研究。结果显示,该区珍子山组沉积时期为温暖湿润的气候条件,沉积环境主体为陆相还原环境。地球化学特征所反映出的沉积环境为页岩气的成藏及储集提供了良好的条件。

| Abstract: | Through the analysis of rock association，fossils and element geochemistry of the profiles near Jins- han village in Fujin uplift of Sanjiang Basin，the authors studied the sedimentary environment of Zhenzishan Formation． The results showed that during the sedimentary period of the Zhenzishan Formation，it was humid and warm climate and the sedimentary condition was continental reducing environment． Geochemical characteristics reflected that sedimentary environment provided favour conditions for the accumulation and reservoir of shale gas． |
