从已获资料分析出我国西北地区含铀钙结岩(膏结岩)主要发育在古盐湖中。它是由膏结泥岩、膏结砾岩、膏结砂岩等组成。含铀层数多,工业矿化只在近地表一层或两层,含铀矿物主要是硅钙铀矿、钒钙铀矿、钒钾铀矿等。以西北区域地质特征及古气候条件为依据,结合区调、普查,勘探成果进行综合对比,编出了钙(膏)结岩分布略图,并认为钙(膏)结岩型铀矿化是西北地区值得探索的一种新类型。
From the obtained data, it is found that the uranium-bearing calc-karatite (gingko-karat) in northwestern China mainly develops in the ancient salt lake. It is composed of creamy mudstone, gypsum conglomerate, creamy sandstone and other components. Containing more than uranium layer, industrial mineralization only in the surface layer or two layers, containing uranium minerals are mainly calcium-calcium uranium ore, vanadium calcium uranium ore, vanadium potassium uranium ore. Based on the geological characteristics and palaeoclimatic conditions in the northwestern region and the regional contrast, census and exploration results, the comparisons of calcareous (calcareous) knot rock distribution are made and it is considered that calcite A new type of area worth exploring.
