| 中文摘要: |
| 克停哈尔铜钼多金属矿床位于东昆仑祁漫塔格成矿带东段,矿区出露主要地层有古元古界金水口岩群和寒武—奥陶系滩间山群,金水口岩群碳酸盐岩是形成夕卡岩型铁多金属矿的有利岩性,华力西期闪长岩、印支期中酸性花岗岩类发育,印支期似斑状花岗闪长岩是该区铜钼矿主要含矿岩体。区内构造活动强烈,北西西向—北西向的压性、压扭性断裂组成了区域主体构造骨架,北东向构造形成较晚,是主要的控矿构造。该区具有多期次系列成矿的特征,形成以含矿斑岩体为中心的斑岩型钼矿化,外围为夕卡岩型铁多金属矿及脉状铅锌矿化的岩浆热液成矿系列,文章通过初步总结矿床地质特征,建立了找矿标志,为该区及区域同类型矿产勘查提供参考。 |
| 英文摘要: |
| The Ketinghaier polymetallic Cu-Mo deposit occurs at the eastern part of Qimantage metallogenic belt in the eastern Kunlun mountain range. The main strata outcropped in the area are Jinshuikou rock group of the Paleo-Proterozic period and Tanjianshan group of Cambrian and Ordovician period. The carbonatite of Jinshuikou rock group is the favorable lithology by the formation of skarntype polymetallic iron deposit. The Variscan epoch diorite and Indo-Chinese epoch intermediate-acid granitoids are extensively developed, The porphyraceous granodiorite of Indo-Chinese epoch is the main ore-bearing intrusive of Cu-Mo deposits in this deposit area. The tectonic activities in this area were intense,the NWW-NW trending compressive and compresso-shear faults composed the regional tectonic framework,and the NE-trending structure was formed at later stage which is the main ore-controlling structure. The copper-molybdenum mineralization was formed by multistages process, the copper-molybdenum mineralization formed in the centre of ore-bearing porphyry, and the skarntype polymetallic iron deposit and veintype lead-zinc mineralization of magmatic hydrothermal type metallogenic seriesare located in the periphery. The geological characteristics of Cu-Mo deposit are preliminarily summarized, and the prospecting criteria was set up which guide the prospecting in the area as well as similar type deposit in the region. |
