祁漫塔格地区黑山铀矿点矿化特征及控矿因素

Study on uranium metallogenic character and controlling factors of Heishan uranium occurrence in the Qimantage region

在祁漫塔格地区黑山铀矿点成矿特征研究基础上,总结该区铀矿控矿因素为变质片岩混合岩、花岗岩体边缘过渡带、晚期岩脉、断裂构造和热液蚀变联合控矿;提出了该区铀矿找矿标志:围岩标志、构造标志、蚀变标志和放射性标志;指出在祁漫塔格地区寻找碎裂蚀变岩型铀矿的重点区域为祁漫塔格主脊断裂两侧的花岗岩边缘过渡带。

By studying uranium metallogenic character, it is pointed out that the uranium mineralization in this area is controlled jointly by migmatite zone of metamorphic schist, transitional facies of the granite body edge, later veins, structural system and hydrothermal alteration. The prospecting criteria in this area of uranium, such as rock marks, structural sign, altered signs and radiological signs, were pointed out. It is indicated that the key regions which could be found altered cataclastic rock type uranium deposits in Qimantage area are the edges of granites both sides of Qimantage backbone fault.
