【摘要】 驱龙斑岩铜(钼)矿床位于西藏冈底斯成矿带东段,具有巨大找矿潜力。这里主要通过岩石地球化学分析,确定矿床含矿斑岩属于过铝质高钾钙碱性岩石,具有明显的埃达克岩岩浆亲合性,并可初步断定驱龙及冈底斯成矿带典型斑岩铜矿床的含矿斑岩具备C型埃达克岩特征,其构造背景应为碰撞造山期后的伸展条件,这将对该带成矿环境的深入研究和进一步找矿有所启示。更多还原

【Abstract】 The Qulong porphyry copper (molybdenum) deposit is located in the eastern sector of Gangdese porphyry copper belt, having great potentialities for ore prospecting. By rock geochemical analyses in the paper, the ore-bearing porphyries in the deposit have been proved as peraluminous high-K cale-alkaline series rocks and showing Adakite magmatic affinity with particularity. And it could be preliminarily inferred that the ore-bearing porphyries of Qulong and other typical porphyry deposits in Gendese belong to the Adakite II rocks. The post-collisional crustal extension should its main structural setting. All of these would be helpful to further study of the metallogenic environment and ore prospecting.更多还原
