大红山铁矿发现于1957年,关于其矿床成因,仍存在诸多争议。大致可分为两个阶段,20世纪70―90年代的火山喷流沉积-变质改造型(杨应选,1972;钱锦和等,1983;杨应选等,1988;孙家骢等,1993)以及20世纪90年代至今的火山喷流沉积-热液改造型矿床(秦德先,2000;吴孔文,2008;候增谦等,2003)。近几年,相继有少数学者将大红山铁铜矿与IOCG矿床联系起来(Zhao et al.,2010)。对于矿床类型及成因
Dahongshan Iron Deposit was discovered in 1957, there are still many controversies about the cause of its deposit. It can be roughly divided into two stages: volcanic jet sedimentation-metamorphism (70s-90s) in the 20th century, and the metamorphism (Yang Yingxuan, 1972; Qian Jinhe et al., 1983; Yang Yingxuan et al., 1988; To date, volcanic jet deposition - hydrothermal remodeling deposit (Qin Dexian, 2000; Wu Kongwen, 2008; Hou Zengqian et al., 2003). In recent years, a few scholars have successively linked the Dahongshan Iron and Copper Mine to the IOCG deposit (Zhao et al., 2010). For the deposit type and genesis
