论四川盆地三叠系含盐系碳酸盐组分分布及其成盐标志意义

ON DISTRIBUTION OF CARBONATE COMPOSITIONS AS A GUIDE OF SALT-FORMATION OF THE TRIASSIC SALT-BEARING FORMATION IN SICHUAN BASIN

四川盆地三叠系含盐系普遍含碳酸盐组分，其中发现大量菱镁矿，它与成盐关系密切，是纵、横向盐系剖面成盐相的对比标志。

The Triassic System in Sichuan Basin consists in common of carbonate compositions including magnesite which bears close relationship to salt-formation and is regarded as a guide for the correlation between salt-bearing profiles.
