新疆阿尔泰金矿分布地质特征

The geological features of goldmine distribution in Aite Xinjiang

新疆阿尔泰横跨西伯利亚和哈萨克斯坦两大板块的接合带。该区经历了长期地质构造活动、褶皱构造和断裂构造发育 ,故在这种地质背景条件下形成了多种含金建造 ,为金矿的形成奠定了物质和动力基础。金矿类别主要为变质火山岩及碎屑岩型金矿和侵入岩有关类型金矿。金矿带受区域构造浅控制 ,呈北西向展布。根据成矿期同位素年代学研究 ,阿尔泰金矿主要成矿时期为 40 8～ 2 86

Xinjiang Aite is situated on the juncture of Siberian and Kazakstan plate.The district has undergone a long geological structure movement,drape and rupture structure under such geological conditions, several geolosical structures containing gold were formed and such formation provides material and dynamic basis for goldmine. The main types of goldmine are metamorphic-rock & kataclastic-rock goldmine and irruptive rock goldmine.The structural line controls golden mineralized zone which extend from north to west.Based on isotope analysis,Aite goldmine was made in 408-286Ma.
