| 摘 要： | 四川盆地三叠纪蒸发岩系普遍含碳酸盐组分 ,除方解石、白云石外 ,常出现大量菱镁矿。三种碳酸盐矿物的分布 ,可反映出盆地海水浓缩程度 ,进而分析成盐盆地浓缩淡化发展进程 ;可作为纵、横向蒸发岩系剖面成盐相的对比标志

| Abstract: | Triassic evaporite series in Sichuan basin contains high amounts of carbonate components made up of calcite, dolomite as well as of rich magnesite. How the three evaporite minerals distributed in the basin can give a hint of inspissation level of the sea water and according to that, we can review the whole progression of its inspissation to desalination. These evaporite minerals may be regarded as marks for the correlation between different salt-forming lithofacies |
