西藏金矿资源分布规律、矿化类型及找矿方向

The Distribution,Mineralization Types and Prospecting and Exploration of the Gold Deposits in Xizang

西藏的地质工作程度较低,金矿资料甚少,这对较系统地、深入地研究区内金矿特征和成矿规律造成一定困难。尽管如此,已有的资料已显示出金矿是西藏极具潜力的一个矿种,尤其是冈底斯构造岩浆带、雅鲁藏布江结合带及班公湖-怒江结合带两侧已被大多数高原地质工作者认同为金和?..

Four metallogenic provinces have been discriminated for the gold mineral resources in Xizang,southwestern China including the South Xizang metallogenic province,East Xizang metallogenic province,North Xizang metallogenic province and Gangdise metallogenic province.The mineralization types and ore controlling factors in individual metallogenic provinces are discussed with the emphasis on the ore controlling processes of the faults and rifts and volcanic magmatic activity on the formation of the gold deposits,especially the impacts of the geomorphological features caused by the rapid uplifting of the plateau from the Tertiary onwards and the Quaternary geological features on the formation of the gold deposits.In addition,the target areas for the prospecting and exploration of the gold deposits in Xizang have also been delineated in the present study.
