【摘要】 碎裂蚀变花岗岩型铀矿床是当前我国找矿的主攻方向之一，它具有大碎裂带、以交代作用为特征的大蚀变带。低品位大矿量易浸出的特点。该类型矿床形成的主要地质条件是：地台边缘活动带或褶皱带的花岗岩隆起区；受非造山的大复式花岗岩基内自变质作用发育的小岩体和双断裂夹持区或断裂构造结的双重控制；酸交代或碱交代蚀变发育区；红层不整合覆盖、负地形、表生叠加富集区。同时，强调了在找矿过程中要加强地浸试验和经济技术评价。更多还原

【Abstract】 Cataclastic-altered granite type uranium deposit is one of the main prospecting objects inour country at present.It is characterized by large cataclasis and alteration zone and a greatvolume of low grade easily leached ore.The main geologic settings for its formation are upwarping region in the marginal mobile zone of platform or folding belt;doubly controlled bysmall intrusions with intensive autometamorphism within anorogenic multiple granitebatholith and by sandwiched block between two faults or fault intersecting area;region withdevelopment of acidic or alkali alteration and region of negative relief,unconformably coveredby red beds and superimposed by supergene enrichment process.Emphasis should be placedon the in-situ leaching experiment and economic-technical evaluation in prospecting process.更多还原
