哈萨克斯坦古河道砂岩型S铀矿床成矿特征

Metallogenic characteristic of paleochannel type sandstone-hosted uranium deposit S in Kazakhstan

文章应用活化构造成矿理论,对哈萨克斯坦古河道砂岩型S铀矿床进行成矿特征分析,并与层间氧化带砂岩型Ⅰ矿床的成矿特征进行对比,认为S铀矿床成矿受大地构造、古潜水成矿作用、层位和岩性岩相、断裂构造及岩浆岩等控制,铀成矿具有多阶段复成因的特点。据此,从对企业生产的角度提出一些建议。

The metallogenic characteristic of paleochannel type sandstone-hosted uranium deposit S in North Kazakhstan was analyzed with the metallogenic theory of tectonic activization and compared to that of interlayer oxidation type uranium deposit I.It was believed that the formation of deposit S was controlled by geotectonics,paleo-phreatic oxidation,strata,lithology,lithofacies,fault,and magmatite and beares the character of muliti-genesis.Some suggestion has been proposed thereafter for the uranium production.
