| 摘 要： | 四川盆地及其周缘地区下二叠统碳酸盐岩中，不同程度地发育着一些细晶至粗晶白云岩和白云质灰岩，前人将其解释为淡水透镜体混合白云石化的产物。根据野外及室内薄片观察，并结合阴极发光、碳氧稳定同位素、地球化学分析、包体均一温度和有序度的综合研究，认为这类白云岩主要是由埋藏白云石化作用形成的。

| Abstract: | There are some fine-to coarse-grained dolostones and dolomitic limestones in the lower Permian in Sichuan basin and its peripheral regions, which are good reservoir in Sichuan basin. Since 70 ,s, these rocks has been interpreted as the products of mixing-zone dolomitization in freshwater lens. Based on the comprehensive study on field occurrences, optic features, cathodoluminescence, carbon and oxygen isotopes, trace elements, homogenized temperatures of fluid inclusions and ordering, the dolostone rocksare considered to result from burial dolomitization. |
