摘    要:四川渠县三叠系膏盐产于碳酸盐岩中,二者交互沉积,具明显的旋回性。根据岩性组合、生物组合、沉积构造及地球化学特征分析,该区碳酸盐岩形成于潮下至潮上的各种环境,而膏盐则主要沉积于潮上带的浅水盆地和大陆盐湖。

关 键 词:碳酸盐岩  膏盐  潮坪  台地  四川渠县  三叠系

Abstract:The gypsium-salt. deposils in Qu-Xian, are hosled in Triassic carbonate sequence. Both gypsium-salt and carbonate rocks are deposited on a carbonate platform, while the carbonate rocks in an environment of tidal flat, the gypsium-salt beds were mainly formed in shallow water basins and in saline lakes of supratidal zone.The. formation of gypsium-salt is controlled by the movement of the Yanglze plateform.
Keywords:cnrbonalc rock  gypsium-salt  tidal flat  platrfom  Qu-xian si province   triassic system
