冈底斯成矿带东段汤不拉斑岩钼（铜）矿的发现及意义

汤不拉斑岩钼(铜)矿床位于冈底斯东段的火山岩浆弧中,形成于印度-欧亚大陆碰撞后的构造环境,成矿与花岗斑岩、石英斑岩等斑岩体有关,并受多期次构造活动的影响,产于多种方向的构造结合部住,是冈底斯东段新发现的最具潜力的斑岩钼(铜)矿床.系统地介绍了该矿床的成矿地质背景、矿床特征.该矿床的发现使冈底斯斑岩铜矿带向东延伸了上百公里,又将其向世界级巨型斑岩铜矿带推进了一步,对西藏经济的跨越式发展有着重要的意义.

Discovery of the Tangbula porphyry molybdenum-copper deposit in the eastern segment of the Gangdise metallogenic belt and its significance

The Tangbula porphyry molybdenum-copper deposit, situated in the volcano-magma arc in the eastern segment of the Gangdise, formed in a post-India-Eurasia collision tectonic environment. Mineralization was related to granite porphyry and quartz porphyry and affected by multi-stage tectonic activities. This deposit, occurring at the site of junction of structures of multiple trends, is one of the most potential porphyry molybdenum-copper deposits found in eastern Gangdise recently. This paper systematically introduces the geological setting characteristics of the deposit. Due to the discovery of this deposit, the Gangdise porphyry copper belt extends eastward for up to 100 km and the copper belt further approaches a world-class giant porphyry copper belt. Furthermore, the discovery has great significance for Tibetan economic striding development.
