    • 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.
