摘　　要：青海省龙尾沟铜、金矿床是近年来阿尔金山南麓地区找矿工作所取得的重大突破,已探明铜、金矿体与花岗斑岩脉具有直接成因关系。从地质和地球化学特征上讨论了花岗斑岩脉的特征与成矿的关系,借此了解对龙尾沟铜、金矿床成因的认识。The Longweigou porphyry copper deposit in Qinghai Province is an important deposit discovered in southern Ahun Mountains in recent years. It has been proved that the Cu （Au） ore bodies are directly related to the granite-porphyry veins. Based on geological and geochemical background, this paper has discussed the relationship between the porphyry veins and the ore-forming process, and put forward the metallogenic mechanism of this porphyry Cu （Au） deposit.
