已有的研究表明,斑岩铜矿床不仅可以产于与大洋板片俯冲有关的岛弧及陆缘弧环境,也可产自与俯冲无关的碰撞造山带和陆内环境。相对于弧环境含矿斑岩的成因,人们对后俯冲环境含矿斑岩成因理解要浅显得多。位于我国东部的德兴超大型斑岩铜金矿床,其形成时区内明显处于陆内环境,因此,查明其岩浆起源,将有助于理解后俯冲环境斑岩铜矿床的成因。 Previous studies have shown that porphyry copper deposits can be produced not only in island arcs and continental arcs associated with oceanic plate subduction but also in collision orogenies unrelated to subduction. Compared with the origin of ore-bearing porphyries in the arc environment, people have a much lighter understanding of the genesis of the ore-bearing porphyries in the post-subduction environment. The Dexing super-large porphyry Cu-Au deposit located in the eastern part of China is clearly located in the intracontinental environment in the formation time zone. Therefore, the identification of its magmatic origin will help to understand the genesis of the post-subduction environment porphyry copper deposit.
