| 中文摘要: |
| 东倾沟地区位于阿尼玛卿构造带东段的2个二级构造单元交汇衔接部位，构造、岩浆活动强烈。1∶5万水系沉积物测量圈出19处地球化学综合异常，其中乙类13处、丙类6处。在成矿地质条件分析基础上，结合已知矿（化）点信息，划分5个成矿远景区，初步优选4个找矿靶区，具有良好的铜钴金锑多金属矿找矿潜力。 |
| 英文摘要: |
| Dongqinggou area is located in the east A'nemaqen structural belt where two tectonic unit II joint and strong structural and magmatic activities took place. River sediment survey at scale 1:50000 is conducted here and are outlined 19 integrated geochemical anomalies of which 13 are B-type anomalies and 6 C-type. Combined with information of the known ore deposits and occurrences the metallogenic geological condition is analyzed and 5 prospective metallogenic areas are delineated. 4 of the five areas are optimized to be prospecting targets with potential for prospecting Cu-Co-Au-Sb polymetallic ore. |
