据高灵敏度航空伽玛能谱资料探讨内蒙巴彦浩特盆地（腾格里沙漠）第四系成钾远景

巴彦浩特盆地自中生代至今一直是一自流水的构造盆地，其具有成钾的构造、气候、水文以及古盐释放等有利条件。该区存在着高灵敏度航空伽玛能谱测量发现的现代高钾异常区，由区内已知盐类矿床（点）的存在及铀、钍元素的地球化学的分布特点知，高钾异常与含钾的盐类物质密切相关。高钾异常的分布及其形态特征表明了本区可能存在较深层卤水，并高钾异常的形成是由于沙丘带与盐湖带问的风积作用、两者间的内循环作用以及两者对较深层卤水存在的蒸发作用的共同结果。根据统计及估算，本区可称之为一具一定远景储量的钾盐远景区。它反映了钾盐富集的一种不同形式，实则体现了构造、气候、水文、盐湖、沙漠五者的密切相关和极好的统一，是沙丘（山）型钾盐成矿模式的代表。

A Preliminary Study of Potash Potential Resources in the Bayinhaote Basin (the Tenygeli Desert) Based on Aerial Gamma (RAY) Spectrometric Data

Even since Mesozoic era, the Bayinhaote basin, all the time, is an intermontane artesian water basin, potash minerogenetic advantage conditions that is the structure, climate, hydrology and material source(release of paleosaline) exist in the area. A modern higher K-anomaly area has been descovered in the basin by high-sensitive aerial gamma (ray) spectrometry survey. The distribution feature of the known saline deposits (point) and Thorium and Uranium element show that the K-anomalies is closely related with K-bearing saline substance. The distribution regular and morphological property of the K-anomalies illustrate that brine of deeper-layer may exist in the area. Forming of the K-anomalies is the result of aeolic processes, internal circulating and evaporating for deeper-layer brine between the sand dune zone and the saline lake zone. Based on statistics and estimation the area is a prospect region of potash resources, the area represents a different form of potash accumulating that reflects a good unification of five aspects which are structure, climate, hydrology, saline lakes and desert that are closely related each other' It is a representative model of minerogenetic of liquidus potash deposit of sand dune (hill) form.
