青海省牛鼻子梁-盐湖北山地区铜镍稀有稀土矿成矿规律及找矿远景

Metallogenic regularity and prospecting potential of Cu Ni rare and rare earth ore in Beishan beam and Beishan area,Qinghai Province

青海省牛鼻子梁-盐湖北山地区位于柴达木盆地西北缘,区内矿体的形成与古元古代达肯大坂群地层、构造作用及岩浆作用有着极为密切的关系。本文以现有矿产勘查成果为依托,以与超基性、基性岩有关的岩浆型铜镍硫化物矿、与中酸性侵入岩有关的稀有稀土矿为主攻矿种,大致查明该区成矿地质背景、成矿条件等,总结成矿规律,进一步扩大找矿远景。

The Qinghai Niu nose beam-Saline Lake Beishan area is located in the northwest margin of the Qaidam Basin.The formation of the ore body in the area is closely related to the Paleoproterozoic darkamaka group,tectonism and magmatism.Based on the existing mineral exploration results,this paper mainly focuses on the rare rare earth ores related to the ultrabasic and basic rocks,and the rare rare earth ores related to the intermediate acid intrusive rocks.The ore-forming geological background and the metallogenic conditions are roughly identified,the metallogenic regularity is summarized and the prospecting prospect is further expanded.
