摘要
铁矿浆（包括矿床和矿化）、斑岩铜矿和海相火山岩铜矿均是火山－岩浆作用的产物。铁矿浆通常形成于构造环境从引张发展至挤压过程中并以挤压条件为主时，介于斑岩铜矿和海相火山岩铜矿的成矿条件之间，其成因及时空分布与斑岩铜矿更加密切，多出现于陆相或海陆交互相环境。天山－兴盟褶皱系是斑岩铜矿及矿浆型富铁矿的找矿远景区。
Iron ore magma, including iron deposit and iron mineralization, porphyry copper deposit (PCD) and marine volcanogenetic (massive sulfide) copper deposit (MVCD) are all results of volcanism magmatism. The magma usually occurred in the more compressive tectonic setting than MVCD, and in the more tensional environment than PCD. Compared to MVCD, it was closely to PCD in genesis, distribution and mineralization period, and was mostly located in the setting of continental or continental marine facies. The Qilianshan fold system is a prospective area of MVCD, and the Tianshan Xingmeng system is considered as favourable area to prospect PCD and the iron riched deposit of the ore magma type.
