摘　　要：以纳日贡玛斑岩型钼铜矿床为例,对青海省斑岩铜矿产出的地质构造环境、地质特征、成矿地质条件、含矿建造等条件进行了综合分析。在此基础上,对本省斑岩铜矿的找矿方向进行了初步探讨,提出了斑岩型铜矿床的区域构造-岩浆岩带、区域地球物理、地球化学、围岩蚀变等找矿标志,划分出有远景的五大斑岩型铜矿成矿带。Taking the Narigongma porphyry copper deposit as an example, based on the comprehensive analysis of the conditions of porphyry copper deposit in Qinghai including its geological tectonic environment, geological characteritics, metallogenic condition and mineral-bearing construction, etc., the article has primarily discussed the ore prospecting orientation of the porphyry copper deposit in Qinghai, and put forward some prospecting indicators of porphyry copper deposit involving regional structure-magma belts, regional geophysics, geochemistry, country rock alteration etc.. Five perspective metallogenic belts of porphyry copper deposit have also been outlined.
