扬子地块西南缘是我们前寒武纪地层出露较多、较完整的地区,是进行前寒武纪地质和成矿作用研究的重要地区,该区出露的前寒武纪地层中赋存的铜-铁矿床以矿床个数多、规模大、伴生多金属成矿等特征,受到国内外矿床地质学者的广泛关注(如:杨时惠等,1987;周名魁等,1988;吴懋德等,1990;陈好寿等,1992;冉崇英等,1993;李巨初等,1996,1994;耿元生等,2008;何德锋等,2010;龚琳,2011;关俊雷等,
The southwestern margin of the Yangtze block is an area where more and more Pre-Cambrian strata were exposed. It is an important area for the study of Precambrian geology and mineralization. In the Precambrian strata exposed in the area, Deposits of copper - iron deposits to the number of deposits, large-scale, accompanied by multi-metal mineralization and other characteristics, by domestic and foreign deposit geologists have been widely concerned (such as: Yang Shihui et al., 1987; Zhou Mingkui et al., 1988; ; Chen Heshou et al., 1992; Ran Chongying et al., 1993; Li Juchu et al., 1996,1994; Geng Yuansheng et al., 2008; He Defeng et al., 2010; Gong Lin, 2011; Guan Junlei et al.
