| 摘 要： | 川西北地区中二叠统栖霞组中上部不同程度发育细晶-粗晶的白云岩、灰质白云岩和白云质石灰岩,是该地区有利的储集层.前人对该类白云岩的成因认识有大气淡水与海水混合成因、埋藏成因和"玄武岩淋滤化"作用成因等3种.根据野外及室内薄片观察,结合阴极发光、碳氧同位素、地球化学等分析资料以及区域地质特征,综合分析认为该类白云岩是由埋藏... |

| Abstract: | There developed some fine to coarse dolostones,lime-dolomites and dolomitic limestones in the Middle Permian Qixia Formation of northwest Sichuan Area,which were good reservoirs in Sichuan Basin.Previous research results showed that three kinds of genetic interpretations were obtained,such as mixing-zone dolomitization in freshwater lens,burial dolomitization and basalt leaching.Based on the data of field observation,optic features,cathodoluminescence,carbon and oxygen isotopes,trace element analyses,homoge... |
