新疆阿希勒金矿床地质特征及找矿标志

GEOLOGY AND ORE PROSPECTING OF AXIL GOLD DEPOSIT IN XINJIANG

阿希勒金矿位于新疆阿勒泰地区哈巴河县一带,属克兰成矿带的哈巴河-阿巴宫成矿亚带,是中、哈、蒙阿尔泰多金属成矿带的一部分,西南侧与多拉纳萨依-赛都矿带相邻。区域上岩浆活动频繁,构造较为发育,早期韧性剪切断裂与区内成矿关系十分密切,金矿体产于强韧性变形变质带核部,构造控矿特征十分明显,含金石英脉主要赋存在华力西期岩浆杂岩体后期构造挤压破碎带中,寻找北东向断裂构造挤压破碎带中的矿化石英脉是区内寻找金矿的直接标志。

The Axil gold deposit occurring in the area of Habahe County of Altay region,Xinjiang,is a part of the Altai polymetallic metallogenic belt and adjacent to the Doranasayi-Sedu ore belt to the southwest,which belongs to the Habahe-Abagong metallogenic subzones of the Klan metallogenic zone.The region is characterized by frequent magmatic activities that occurred in the history and structures developed well.Gold mineralization is closely associated with early formed ductile shear faults and the ore bodies are present in the centre part of the tough deformation and intensive metamorphic zone,showing evident ore-control features by structures.Gold-bearing quartz veins mainly occurred in the late tectonic crushing zone of the Variscan magmatic complex,indicating that the mineralized quartz veins in the compression fracture zone of NNE fault structure are the direct marks for gold prospecting in this region.
