| 中文摘要: |
| 四川盆地寒武系盐卤资源开发历史悠久，而固矿石盐层乃是20世纪80年代后期从油气探井中才发现的，它为我国卤化物矿物增添了一个新的成盐地质年代，与此同时也极大的改变了华南寒武系古地理面貌，为我国盐砂勘查及找钾预测提供了新的资料。然而至今四川盆地寒武纪盐类工作程度仍然有限，就现有少量资料对四川盆地寒武系成盐古地理背景、盐系沉积剖面特征、石盐矿物特征及盐卤水化学特征等方面作一概略简介和论述。 |
| 英文摘要: |
| Cambrian bittern resource exploitation had a long history in Sichuan basin. However, solid salt ore was not found until late 1980s in which the petroleum exploratory wells began to be placed in the basin. That added a new geological age for halide mineral and changed Cambrian paleogeograpic outlook greatly. It supplied new data for salt mine exploration and finding potassium, but the related work on saline material was deficient. The paper did a briefly discussion on Cambrian paleogeographic environment, cross section characteristic of salt sediment, halite mineral characteristic and bittern hydrochemistry characteristic. |
