西藏雅鲁藏布江成矿区斑岩型铜矿基本特征与找矿潜力

雅鲁藏布江成矿区位于青藏高原腹地,地质工作程度极低,但成矿条件十分有利.近年来中国地质调查局在该成矿区部署开展"十五"期间重点实施项目"雅鲁藏布江成矿区铜多金属资源调查评价",通过几年的工作,在斑岩铜矿资源评价方面取得了重要进展,目前已初步控制了4个大型远景的斑岩型铜矿床,新提出了一批可供进行预查或普查的新矿产地,初步揭示出该成矿区铜矿资源的巨大潜力,中国西部又一大型铜矿产资源基地的前景在西藏已经初步显现.

BASIC CHARACTERISTIC OF PORPHYRY COPPER DEPOSITS AND ITS PERSPECTING IN YALUZANGBUJIANG METALLOGENIC PROVINCE, TIBET

Located at the central region of Qinghai-Tibet Plateau, Yaluzangbujiang metallogenic province is one of the most lowest studying degree regions in western China at present, but the metallogenic conditions in this Gangdise region is hopeful. Focusing on the geological exploration of porphyry copper ore deposits in Yaluzangbujiang metallogenic province, a project named "Copper ore and silver-bearing polymetallic ore exploration and assessment" had been complemented by China Geology Survey (CGS). Base on the updated results and advances gained from the project, four miniatures of large-scale porphyry copper deposit had been controlled, and a group of porphyry copper ore spots had been founded in the Gangdise region. The basic characteristic of porphyry copper ore deposits and prospecting in Yaluzangbujiang metallogenic province are discussed. It is pointed out that in coming years Yaluzangbujiang metallogenic province should become another large-scale copper ore base in the western region of China.
