摘　　要：康图盖石英岩矿是阿尔金山腹地新发现的石英岩矿床,赋存于中元古界英格里克构造(蛇绿)混杂岩带复理石变质岩中。矿体呈层状、透镜状,矿物组合主要为石英、白云母、黑云母,少量黄铁矿、石榴子石、绿泥石,细粒变晶结构、半自形粒状结构,块状构造。矿床成因为沉积变质型石英岩矿,矿床规模为中型。康图盖石英岩矿床硅铁用石英岩资源潜力巨大。The Kantugai quartzite deposit in Ruoqiang County,Xinjiang is a new quartzite deposit for ferrosilicon in the hinterland of Altun Mountain,Xinjiang.The deposit occurs in two mica and Muscovite quartz shillings in the flysch metamorphic strata of the(middle)Proterozoic Ingrique structure(ophiolitic)melange zone.The deposit consists of more than twenty stratified and lenticular quartzites.The mineral association is mainly composed of quartz,Muscovite,biotite and a small amount of pyrite,garnet and chlorite.The main structure of the ore is fine grained blastoblastic structure,followed by semi-idiomorphic granular structure.The main structure of ore is block structure.The deposit is a sedimentary metamorphic quartzite deposit.Quartzite in the mining area is large in quantity and scale.At present,only some sections of quartzite ore bodies have been systematically controlled,and the deposit scale has reached above medium size.There are still a large amount of quartzite in the mining area that has not been controlled by engineering,and the quartzite mineral resources for ferrosilicon in Kangtugai quartzite mining area have great potential.
