云南省香格里拉市铜厂沟斑岩型钼铜矿床成因模式探讨

Genetic model of copper and porphyry molybdenum copper deposit in Shangri-La,Yunnan

云南西部香格里拉斑岩带属于西南"三江"义敦岛弧的南端,从东到西可划分为明显的3个部分。香格里拉地区在侏罗-白垩纪为陆内汇聚阶段,晚期(88Ma～80Ma,杨岳清等,2002)发育碰撞(S)型酸性侵入岩分布于铜厂沟(85±2Ma)、休瓦促(83±1Ma)、热林(81.2±2.3Ma)等地区,在构造有利部位伴有钼、铜、金银、铅锌矿化。

The shangri-la porthole belt in western yunnan belongs to the southern tip of the"sanjiang"of the southwest"sanjiang",which can be divided into three distinct parts from east to west.Shangri-la region for intracontinental convergence in Jurassic and cretaceous stage,late(88Ma^80 Ma,yue-qing Yang,etc.,2002)development of collision type(S)of acidic intrusive rocks distributed in copper factory groove(85±2 Ma),Hugh watts for Lin(83±1 Ma),heat(81.2±2.3 Ma)and other regions,in tectonic positions with molybdenum,copper,gold and silver,lead and zinc.
