摘　　要：河草坑铀矿田位于大富足岩体北西部接触带附近,构造、岩浆及热液活动强烈,发育多种类型的铀矿床、矿点及放射性异常点带。其中发育在花岗岩外带含碳变质岩中的岩浆热液型铀矿,以及发育在花岗岩内带的岩浆热液叠加氧化淋滤而成的复成因铀矿,是今后的找矿目标类型。Hecaokeng uranium ore field is located in northwest contact zone of Dafuzu granite body in southern Jiangxi province. In this ore field, tectonic and magmatic and hydrothermal activities were strong. So many kinds of uranium ore deposits, spots as well as radioactive anomalies occur. Ore-controlling factors are varied. The two uranium ore types, one being in the carbonaceous metamorphic rocks of the exocontact, formed by magmatic hydrothermal mineralization, another in the innercontact, magmatic hydrothermal mineralization was surperimposed by groundwater oxidizing-leaching,are the prostecting target types.
