摘　　要：西藏雄村斑岩型铜金矿是冈底斯成矿带发现的重要的斑岩型铜金矿床,该矿区的成矿期次包括中侏罗世早、晚两期,矿区的成矿构造背景为与新特提斯洋洋内俯冲作用相关的岛弧环境。该区成矿时代比冈底斯传统意义上第三纪与印度-亚洲大陆碰撞过程中有关矿床成矿时代早100Ma左右,这为冈底斯带找矿指明了新的方向。本文将从大地构造演化、构造、岩浆岩、地层等四个方面对雄村式铜金矿找矿地质标志及下一步找矿方向进行分析。The Xiongcun porphyry type copper-gold deposit in Tibet is an important porphyry copper-gold deposit discovered in the Gangdise metallogenic belt.The ore-forming periods of this ore include the early and late stages of the Middle Jurassic,and the ore-forming structures of the mining area.The background is the island arc environment associated with the subduction of the Neo-Tethys ocean.The metallogenic time in this area is about 100 Ma earlier than that of Gangdese＇s traditional sense in the collision between the Tertiary and the Indian-Asian continent,which indicates a new direction for the Gangdese Belt Prospecting.This article will analyze the prospecting geological direction of the Xiongcun copper-gold deposit and its prospecting direction from four aspects：tectonic evolution,tectonic,magmatic rocks,and strata.
