尕尔穷铜金矿床大地构造位置位于班怒带和冈底斯北缘的结合带,南侧为冈底斯—拉萨—腾冲地块,北侧为南羌塘地块。近年来随着班公湖—怒江缝合带西段的地质勘探和研究工作的深入,已成为成为继冈底斯成矿带之后西藏又一重要成矿带~([1~4])。尕尔穷铜金矿床是成矿带中重要的典型矿床,矿石成分研究较薄弱。作者首次通过显微镜鉴定、扫描电镜、电子探针对矿石成分做了系统、深入的工作,为矿床成因、矿物学、矿相学等研究和矿山进一步勘查、综合利用提供了理论依据。
The Ge Erqian copper-gold deposit is located at the junction of the Bangui and the northern margin of the Gangdese with the Gangdise-Lhasa-Tengchong block on the south and the southern Qiangtang block on the north. In recent years, with the deep exploration of geological exploration and research work in the western part of the Bangong-Nujiang suture zone, it has become another important metallogenic belt in Tibet after the Gangdese metallogenic belt. [1 ~ 4] The Gol-poor copper-gold deposit is an important typical deposit in the metallogenic belt, and the ore composition research is relatively weak. The author made the systematic and in-depth work on the ore composition through microscope identification, scanning electron microscopy and electron probe for the first time, which provided the theoretical basis for the research on the genesis, mineralogy and mineralogy of mine and the prospecting and comprehensive utilization of mines.
