青海亚曲硫化物铜镍矿床,位于青海省东部,大地构造位置属于祁连山地槽南部隆起的东南边缘,北临祁连山地槽扎赖—大通山地向斜,东南钦接秦岭地槽海西—印支地向斜,西南为昆仑山海西地槽,呈一由青海湖经日月山、拉脊山向东南延伸的长条隆起地带,构造线方向北西西,局部向北偏转。由于在三个构造单元的交接处,故岩浆活动和构造变动相当复杂,分布最广者为一系列基性—超基性杂岩,该杂岩普遍含镍较高,与本区硫化物铜镍矿床关系密切。
The Qinghai Yaqu sulphide copper-nickel deposit is located in the eastern part of Qinghai Province. The tectonic position belongs to the southeastern margin of the uplifted southern part of the Qilian Mountain Slot, and to the north is the syncline from the Zhalai-Datong Mountain to the Qilian Mountain Slot. The branch is syncline, and the southwest is the Haixi Gully of the Kunlun Mountains. It is a strip of uplift extending from the Qinghai Lake to the southeast through the Riyueshan and Laji Mountain. The tectonic line is northwest and westward, and the part is deflected northward. Because of the intersection of the three tectonic units, the magmatic activity and tectonic changes are quite complicated. The most widely distributed are mafic-ultrabasic complexes, which are generally high in nickel-bearing content and are associated with sulfide copper Nickel deposits are closely related.
