内蒙古额济纳旗阿木乌素锑矿床成因、找矿规律讨论

Discussion on genesis and prospecting regularity of A Mu antimony antimony deposit in Inner Mongolia, Ejinaqi

阿木乌素锑矿床地处西邻塔里木地块,南缘为阿拉善台隆及北祁连走廊过渡带。区内构造运动强烈、频繁,不同时期、不同方向的褶皱、断裂构成的挤压破碎带较发育,多数为近东西向挤压褶皱带。区内矿产明显受该组构造控制。矿体多为脉状,近矿围岩蚀变强烈,主要有碳酸盐化、黄钾铁矾化、褐铁矿化、硅化、黄铁矿化。其成因类型为受构造破碎带控制低温热液锑矿床。

The Ayuwusu antimony deposit is located in the Tarim block in the west, and the southern margin is the transition zone of Alashan Tyrone and the North Qilian corridor. The tectonic movement in the region is intense, frequent,different periods, different directions of folds, fractures constitute the crushing zone is more developed, mostly near east to west extrusion crater. The mineral in the area is obviously controlled by the group. Ore body is mostly vein, near the mine wall erosion is strong, mainly carbonated, yellow potassium iron alumation, limonite, pyrite mineralization. The type of genesis is tectonic fracture zone controlled low temperature hydrothermal antimony deposit.
