新铺子铁矿是四川两会地区的重要铁矿山之一。作者和其他师生曾多次到该矿区配合603队做过一些实际工作。本文谈谈新铺子铁矿的成矿岩石问题。一、地质简况新铺子地处川滇南北带中段东缘,古通安孤弧顶。古通安弧呈东西向展布,向南略突。本矿区周围出露的地层主要是会理群浅变质岩系。由下往上依次为因民组(Pt_1y)、落雪组(Pt_1l)、黑山组(Pt_1h)、青龙山组(Pt_1Q)及双水井组(Pt_2sh)。双水井组与下 Newly-built iron ore is one of the important iron mines in Sichuan’s two regions. The author and other teachers and students have repeatedly to the mine 603 team to do some practical work. This article talks about the metallogenic rocks in the Xindizi iron mine. First, the geological profile New shop is located in the eastern edge of the middle of Sichuan-Yunnan North-South belt, ancient pass Andean arc top. Gu Tong An arc was east-west spread slightly southward. The strata exposed around this mining area are mainly metamorphic shallow metamorphic rocks. From bottom to top, they are Pt_1y, Pt_1l, Pt_1h, Qinglongshan (Pt_1Q) and Shuangshuii (Pt_2sh). Double well group with under
