【摘要】：正达布铜钼矿区位于拉萨市曲水县南木乡达布村一带,隶属曲水县南木乡管辖。矿区距中尼公路沿线的南木乡约15 km,有简易公路相通,南木乡距拉萨市约25 km,有国道相连。大地构造位置属南冈底斯-念青唐古拉板片之冈底斯陆缘火山-岩浆弧带。新特提斯洋在中白垩世向北俯冲,形成了日喀则弧前盆地和冈底斯岩浆弧带。冈底斯岩浆弧带主要由中-新生代中酸性侵入岩和火山岩组成。火山岩主体由拉斑玄武岩系列和钙
[Abstract]:Zhengdabu copper-molybdenum ore area located in Qushui County, Lhasa City, Nan-mu Township Dabu Village area, under the jurisdiction of Qushui County, Nanmu Township. The mining area is about 15 km from Nanmu Township along the China-Nepal Highway, which is connected by a simple highway, and 25 km from Lhasa City in Nanmu Township. The tectonic position is the volcanic-magmatic arc zone of the Gangdis continental margin of the South Gangdis-Nianqingtang Gulaban plate. The Neo-Tethys Ocean subducted northward in the Middle Cretaceous, forming the Xigaze forearc basin and the Gangdis magmatic arc zone. The Gangdis magmatic arc zone is mainly composed of Meso-Cenozoic intermediate-acid intrusive rocks and volcanic rocks. Volcanic rocks are composed of tholeiite series and calcium
