| 中文摘要: |
| 祁漫塔格地区是位于柴达木盆地与昆仑山系之间近东西向的山岭起伏地带,其自元古宙以来,历经新元古代、早古生代、晚古生代以及中新生代的地质构造上的多次开合作用,为该区的铁铜多金属成矿提供了丰富的物质基础。中生代以来的断块活动及其所产生的盆岭构造奠定了该区由北向南的5个隆起、凹陷相间出现的矿化分带格局。由于多期次的构造岩浆成矿活动的复合叠加,形成了该区多元素矿床组合、多类型矿床共生和多层楼矿体叠置复合的成矿特点。文章列举了该区具代表性的5类复合型矿床,强调了该区斑岩+夕卡岩+热液型复合矿床属于海西、印支造山晚期侵入形成,而非岛弧型斑岩。按隆起和凹陷带的成矿特征,采用相应的物化探方法可以实现有效找矿。该区具有进一步寻找铁、铜、铅、锌、金、钴矿床的前景。 |
| 英文摘要: |
| Qimantage area is located in the Qaidam Basin and the Kunlun Mountains between a nearly E-W undulating hills region, since Proterozoic it experiences the late Proterozoic, Paleozoic, Late Paleozoic and Cenozoic geological structure of multiple folding effect. It provides rich material basis for the iron copper polymetallic ore in this area. Since the Mesozoic faulted activity and the basin-range structure laid the district from north to south the five bulges, depression occur alternately mineralization zoning pattern. Due to many times of tectonic magmatic mineralization activity composition, it formed the area much element deposits, many types of ore deposits in combination of symbiosis and multilayer building mineralization ore stacking, compound mineralization characteristics. Listing five representative composite deposit characteristics in the district and emphasizing this zone of porphyry and skarn and hydrothermal type composite deposit and it belongs to the Hercynian Indosinian orogenic, late invasive form, instead of island arc type porphyry. According to uplift and depression of metallogenic characteristics, the corresponding geophysical and geochemical methods are used and effective exploration is carried out.It is proved that there is good prospects for searching Fe,Cu, Pb, Zn, Au, Co deposit. |
