| 中文摘要: |
| 东昆仑克停哈尔地区物化探异常丰富,古元古界金水口岩群大理岩是成矿有利地层,印支期似斑状花岗闪长岩为铜钼矿含矿围岩,岩体中有小的隐伏斑岩体及隐爆角砾岩筒,岩体内北东向构造裂隙发育,围绕岩体已形成了斑岩型铜钼矿、夕卡岩型铁多金属矿及热液脉型铜铅锌多金属矿的岩浆热液成矿系列。由岩体往外依次出现钼、铜、铅锌矿化的分带性,总结区域及矿区地质特征认为,结合物化探异常加强隐爆角砾岩筒为中心的似斑状花岗闪长岩体及花岗斑岩体勘查,将是后期找矿工作的重点。 |
| 英文摘要: |
| Abandunt of geophysical and geochemical anomalies were outlined in the Ketinghaer area,the Paleo-Proterozoic Jinshuikou marble is the main host strata, and the ore-forming parent intrusion is Indosinian porphyritic granodiorite where small scale concealed porphyry intrusion and breccia pipes occur within it and the north-east trending structures are well developed. The porphyry copper- molybdenum deposit, skarn type iron polymetallic deposit and hydrothermal type Cu-Pb-Zn multimetallic deposit were formed around the intrusion which formed the magmatic hydrothermal metallogenic series.From the central to outward of the intrusion, there is apparent mineralizaton zoning, i.e., molybdenium-copper-lead and zinc mineralization from inside to outside. Based on the study of the regional geological characteristics and deposit characteristics, in combination with distribution of geophysical and geochemical anomalies, the future prospecting should focus on the porphyritic granodiorite and granite porphyry with the center of breccia pipes. |
