义敦岛弧南段格咱火山-岩浆弧,是喜马拉雅巨型造山带中的一个复合造山带,起始于印支晚期的大规模俯冲造山作用。以红山-懒中断裂为界,针对印支期而言将斑岩及斑岩成矿划分为西部翁上-雪鸡坪岛弧斑岩成矿亚带(223～249Ma);东部亚杂-普朗岛弧斑岩成矿亚带(203～223Ma)。该期斑岩及斑岩成矿背景、机制、时代与特征,以及红山、普朗斑岩-矽卡岩铜矿等典型矿床前人作了大量研究(曾普胜等,
The Gea volcano-magmatic arc in southern section of Yidun Island is a composite orogenic belt in the giant orogen of the Himalayas, starting with the massive subduction orogeny of the late Indosinian. In terms of the Hongshan-Lazhong fault, the porphyry and porphyry mineralization is divided into the Wengshang-Xuejiaoping Island arc-porphyry metallogenic belt (223 ~ 249Ma) in the western part of Indosinian; Long Island arc porphyry metallogenic belt (203 ~ 223Ma). The background, mechanism, age and characteristics of the porphyry and porphyry mineralization, as well as the predecessors of the Hongshan and Pulang porphyry-skarn copper deposits have been extensively studied (Zeng et al,
