| 摘 要： | 通过对沁水盆地的地质构造、岩浆活动、热演化史及其与上古生界石炭系煤质和镜质体反射率相互关系的研究，认为沁水盆地及其邻区燕山期存在一次重要的构造热事件，并由此促成古生界烃源岩的主生气期发生在晚侏罗世─早白垩世，对该盆地的天然气圈闭成藏和保存具有重要意义。

| Abstract: | There was a tectothermal event during the Middle Yanshanian (Late Jurassic to Early Cretaceous) in Qinshui basin. It was determined by many methods as virinite reflectance, coal step, magmatic activity and tectothermal evolution, etc. This event enabled the hydrocarbon resource rocks of Paleozoic in Qinshui basin to get into the phase of dry gas generation. |
