摘要: 克停哈尔铜钼多金属矿床是2013~2014年在青海省祁漫塔格成矿带新发现的一处小型矿床,大地构造位置属东昆仑祁漫塔格早古生代裂陷槽,位于柴达木盆地西南缘.区内出露地层主要有古元古代金水口岩群和寒武—奥陶纪滩间山群,金水口岩群碳酸盐岩是矽卡岩型铁多金属矿产出的有利地层.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区内铜钼矿的主要含矿岩体.区内构造活动强烈,北西西—北西向的压性、压扭性断裂组成了区域主体构造骨架,多期多组构造交错,为成矿提供了良好通道.矿区成矿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铜钼矿化,外围为矽卡岩型铁多金属矿及脉状铅锌矿化的岩浆热液成矿系列.Abstract: The Ketinghaier deposit is a new discovered small polymetallic Cu-Mo orefield in Qimantage metallogenic belt in 2013~2014. On geotectonics position, it is situated on the early palaeozoic aulacogen of Qimantage in the east Kunlun of Qinghai province, but it is located in the south-east part of Qaidam Basin on geographical location. The main strata exposed in this area are Paleo-proterozic Jinshuikou rock group and Cambrian-Ordovician Tanjianshan group, and the Jinshuikou rock group is the advantageous stratum for the formation of skarn. Variscan diorite and Indosinian intermediate-acid granitoids are well developed, Indosinian porphyraceous granodiorite serves as the main ore-bearing rock-body in this mining area. The tectonic activities in this area were intense, and the NWW-NW trending compression and compresso-shear faults are formed as the tectonic framework of this area, with the characteristic of multi-stages and multi-groups in this area, which provide favorable channels for ore-forming. This deposit has the features of multi-stages mineralization, forming the copper-molybdenum mineralization with the ore-bearing porphyries as its center, while the skarn-type iron polymetallic deposit and the magmatic hydrothermal metallogenic series with vein-type Pb-Zn mineralization were occurred in its periphery.
