【摘要】 斑岩铜矿是世界铜金属资源最重要的来源，通常形成于加厚的（地壳厚度大于35 km）岛弧/活动大陆边缘环境（岛弧型），并伴随长期的岩浆活动和成熟的穿地壳岩浆系统。中国的斑岩铜矿多形成于非岛弧环境（如碰撞造山环境、陆内造山环境和活化克拉通及边缘），其穿地壳岩浆系统的运行方式与机制尚不清楚。本文对长江中下游中生代陆内造山型斑岩铜矿的典型矿床武山铜矿开展了系统的岩相学、岩石地球化学分析和矿物化学研究，构建了武山铜矿穿地壳岩浆系统模型，并在此基础上对比了岛弧型和陆内造山型斑岩铜矿的岩浆系统及其演化特征，揭示了两类斑岩铜矿与岩浆岩时空分布关系的差异性。更多还原

【Abstract】 Porphyry copper deposits are the most significant source of copper resources in the world. They were generally formed in thickened(crustal thickness >35 km) island arc or active continental margin environments(island arc-type), and associated with the long-term magmatic activity and mature transcrustal magmatic plumbing systems. However, most porphyry copper deposits in China were formed in non-island arc settings(collisional orogenic and intracontinental orogenic settings, as well as the margins or interiors of re-activated cratons). The operational dynamics and mechanisms of their transcrustal magmatic systems are still poorly understood. In this paper, we have systematically carried out petrographic, petrogeochemical, and mineralogical studies on igneous rocks associated with the Wushan copper deposit, one of the typical Mesozoic intracontinental-type porphyry copper deposits in the Middle-Lower Yangtze River Valley Metallogenic Belt, and then established a model of the transcrustal magmatic system for the Wushan copper deposit. Furthermore, we conducted a comparative study on the magmatic systems and their evolutionary characteristics between intracontinental-type and island arc-type porphyry copper deposits. Finally, we revealed the differences in the spatio-temporal distribution relationships between magmatic rocks and orebodies in intracontinental porphyry copper deposit and those in island arc-type porphyru copper deposit.更多还原
