| 中文摘要: |
| 为查明新疆乌尔沟地区主要成矿及伴生指示元素、地球化学分布特征及其集散分异规律,完成了1∶50000水系沉积物地球化学测量工作。对Au、W、Cu、Cr等16种元素进行的地球化学特征分析,圈定综合异常32处,并对部分异常进行了查证。综合研究认为区内多金属成矿作用受断裂、地层及岩体控制明显,尤其是冰达板断裂对本区成矿作用的控制。圈定2处Ⅰ级找矿远景区:夏尔嘎-喀尔干吐金、铜找矿远景区,主要元素组合为Au、As、Sb、Ag、Sn、Cu、Pb、Zn、Cr、Co、Ni；包尔特金、铬、铜、钨找矿远景区,主要元素组合为Au、W、Cu、Cr、Ni、As、Sb、Ag、Mo、Bi、Pb、Zn。研究区主要的成矿种类为:金、钨、铬、铜等。研究工作为今后工作提供了地球化学依据,指明了找矿方向。 |

| In order to find out the main ore-forming and associated indicator elements in Wuergou area,the geochemical distribution characteristics and the law of collection,distribution and differentiation,the 1∶50,000 stream sediment geochemical survey was completed.The geochemical characteristics of 16 elements,such as Au,W,Cu and Cr,were analyzed,and 32 comprehensive anomalies were delineated,and some anomalies were verified.Comprehensive study shows that the polymetallic mineralization in the area is obviously controlled by faults,strata and rock masses,especially Bingdaban fault.Two prospecting prospects of Ⅰ grade were delineated.The main element assemblage is Au,As,Sb,Ag,Sn,Cu,Pb,Zn,Cr,Co and Ni in the Xiaerga-Kaergantu gold-copper prospecting prospective area.The main element combination is Au,W,Cu,Cr,Ni,As,Sb,Ag,Mo,Bi,Pb,Zn in the Boerte gold,chromium,copper,tungsten prospecting prospect area.The main metallogenic types in the study area are gold,tungsten,chromium,copper,etc.It provides the geochemical basis for the future work and points out the prospecting direction. |
