| 摘 要： | 山西沁水盆地南缘晋城一带广泛出露寒武系一三叠系地层，其中奥陶系一石炭系地层主要为一套碳酸岩一陆相碎屑岩系沉积，反映了该地区从早古生代到晚古生代由海相向陆海交互相到河流相、湖泊相沉积的演化过程。笔者等对该地区奥陶系一石炭系地层做了初步的地球化学分析，认为该地层中具有生油岩条件，但有机质演化成熟度较高，对找油是不利的，而对找气是比较有利的，有可能成为有希望的新的天然气勘探区．

| Abstract: | The Palaeozoic-Mesozoic formations widely emerged out of the south malginal area of the Qinshui basin,Shanxi,China. Among them the strata of the Ordovician-Carboniferous systems are mainly a set of the carbonatite and elastic rock system deposits,sonle of which are the continental sedimentation. Based on the formations,the evolutionaly process reflected in That area is from nlalille factes to fluvioacustrlne factes and fromthe early Palaeozoic era to the late one.Based on the geochemical analysis, it is consldeled that there are some source beds in the formations.They are of higher maturity in geochemistry. For this rca3oll,it is believed that they will not benefit the discovery of an oil field,but they are favoulable to looking for a gas field.It is expected that the area will become a new region for exploring natural gas. |
