摘要
西藏尼木县汤巴拉铜多金属矿位于西藏中南部、雅鲁藏布江中游北侧冈底斯山脉中段南麓,大地构造位置处于冈底斯~念青唐古拉板片的冈底斯陆缘火山~岩浆弧东部。该区发育有大规模的中酸性侵入岩及火山岩。侵入岩为多期次侵入的复式岩基,具上地幔同源岩浆和壳源演化的特点。多期次岩浆活动给矿区创造了良好的成矿地质条件。
The Tongbala copper polymetallic deposit in Nimu County, Tibet is located in the south-central part of Tibet and the south foot of the middle Gangdise Mountains on the north side of the middle reaches of the Yarlung Zangbo River. Its tectonic location is in the eastern part of the Gangdise continental margin volcano-magmatic arc of the Gangdise-Nianqing Tanggula plate. There are large-scale intermediate-acid intrusive rocks and volcanic rocks in this area. The intrusive rocks are multi-stage intrusive composite batholiths with the characteristics of upper mantle homologous magma and crustal evolution. Multi-stage magmatic activities have created favorable metallogenic geological conditions for the mining area.
