| 中文摘要: |
| 近年来,在大兴安岭成矿区带上已发现多处大型矿床,表明该区具有巨大的找矿潜力。该研究在鄂伦春自治旗奎勒河地区进行了水系沉积物测量,结果发现一处以铜钼钨铋为主的综合异常。对异常进行的种种检查及查证工作显示本异常具有强度大,范围广,浓集中心明显等特点,区内已发现花岗斑岩岩体,普遍发育钾化、硅化及绿帘石化等蚀变。对比该成矿带及国内典型斑岩型铜钼矿床的地球化学、地质、地球物理等特征,显示该区具有寻找斑岩型铜、钼矿床的前景。 |
| 英文摘要: |
| Many large-sized polymetallic deposits have been discovered in Daxinganling metallogenic belt recently where there is great prospecting potential. By conducting stream sediment sampling programme, one integrated geochemical anomaly of Mo-Cu-W-Bi elements was outlined.By field anomaly verification and check, it indicated that the anomaly is characterized with intensity, widely distribution and highly element enrichment concentration. Intensive wallrock alteration including potsssic, silicification and epidotization occur in the mapped granite porphyry. By comparising with known porphyric copper-molybdenum deposits in the belt and other places in China in fields of geology, geochemistry, geophysics and mineralization, there is great potential for discovering new porphyric Cu-Mo deposit in this area. |
