摘　　要：通过莎车坳陷重力异常分析解释以及成盐地质特征分析,表明喀什凹陷有5处明显的低值异常,叶城凹陷有3处明显的低值异常,推断这些异常为低密度盐岩体沉积中心,应是找盐的有利靶区。通过成钾条件分析表明莎车坳陷有很好的成钾盐远景,根据预测划分原则圈定出乌恰-阿克陶和泽普-叶城二个预测区。The analysis of gravity anomaly and potash minerogenetic characteristics of the ShacheDepression, indicate that-there are five obvious low value anomalies inKashi Sag and three obvious low value anomalies inYechengSag.We infer that these anomaliesshould bethe sedimentary center of low densitysalt rock, and also the favorable target areas for potash.In this article, study of potassium condition shows that Shache Depression has good vision for potassium. Besides that, we marking out Wuqia-Aketao and Zepu-Yechengthese two forecasting areasaccording to the prediction principles.
