新疆金窝子—210金矿一带深穿透地球化学异常查证及找矿方向

新疆金窝子—210金矿床位于准噶尔地块与塔里木板块接壤部位的红柳河裂陷槽内。区内主要出露含金背景值较高的下二叠统哲斯群凝灰质砾岩、砂岩和碳泥质页岩等碎屑沉积岩系;构造以近NE向为主,其次为近SN、NW向逆冲断裂体系及呈NE向延伸的叠瓦式背斜和向斜;岩浆岩主要有金窝子花岗闪长岩和二长花岗岩体,呈规模较大的岩基侵位于金窝子背斜核部。矿床类型均为石英脉型,由多条细脉和网脉构成呈透镜状和扁豆体状延伸的脉群。区内第四系覆盖较厚,利用深穿透地球化学测量定位隐伏矿(化)体效果较好,对圈定的地表异常带进行了工程验证,在深部见到对应蚀变体和石英脉。该区总的找矿方向为以寻找金窝子、210金矿体赋存刚性地垒体系及金南、零南向斜两翼构造部位及深部定位与210特征相似的隐伏矿体及其沿走向、倾向延伸部位。

Deep Penetrating Geochemistry Anomaly Verification and Prospecting Direction of the Jinwozi-210 Gold Mine Area in Xinjiang

The Jinwozi-210 gold deposit is located in the Junggar block and Tarim plate on the part of the Hongliuhe rift trough in Xinjiang.The stratum are mainly exposed gold background values higher two Permian Zhesi Group carbonaceous,tuffaceous conglomerate,sandstone,phyllite with clastic sedimentary rocks shale mud system.The structure mainly developed to nearly NE,near SN,NW for the thrust nappe fault system and NE to a series of anticline,syncline extension,magmatic rocks are mainly the granodiorite and monzonite granite,they formed massive batholith and emplaced in Jinwozi anticline core.The deposit types are quartz vein type,which is composed of a plurality of thin veins,stockworks form an extended lens,lens shaped veins.The area was covered by the thick Quaternary,the conventional exploration methods can not work,use of the deep penetrating geochemical measurement for concealed orebody（mineralization） positioning is better,and the surface of the anomalies delineated with verified,deep see corresponding corrosion variants,quartz vein.The prospecting direction in the area to find the Jinwozi,210 gold ore occurrence Horst and gold south,south wing zero inclined tectonic location and deep concealed orebody and along the strike of 210 similar features,tendency of extending part.
