川东三叠系地层分布广,其中中下统硬石膏厚度大,层数多。只有在一定的条件下硬石膏才得以水化成石膏,从而大大提高其经济价值。本文对该区硬石膏的水化与保存条件作了探索分析。 Triassic strata in eastern Sichuan are widely distributed, in which the thickness of middle and lower anhydrite is large and the number of layers is large. Only under certain conditions, anhydrite can be hydrated into gypsum, thus greatly improving its economic value. In this paper, the area of ​​anhydrite hydration and preservation conditions were explored.
