摘要
东川包子铺铁矿床目前控制规模为中型,主要铁矿物为红铁矿。矿床受层位控制,主要赋存于昆阳群大营盘组一段浅变质岩系中下部。矿区共圈定铁矿体3个,其中Ⅱ号主矿体长大于662m,厚2m^146m,品位34.01%,Ⅰ号矿体和Ⅲ号矿体分布零星。结合矿床的宏观产出特征及矿石组构特征,认为矿床的形成经历了早期同生沉积、后期变质及风化改造三个阶段,属沉积改造型铁矿床。
Baozipu iron diposit in Dongchuan region, is a mesoscale deposit, whose main iron-bearing minerals are hematite and limonite. Baozipu iron diposit is controlled by stratums and is hosted in the middle-lower part of epimetamorphic rock series, which belongs to Dayingpan form of Kunyang Group. There are three ore bodies in the iron field, and the Ⅱore body with the length of over 662 m, the thickness of 2~146m and the grade of 34.01%,is the largest one, while the Ⅰ ore body and Ⅲ ore body are both quite small. Considering the macroscopical characteristics of the iron deposit and the features of the ore fabric, We believe that sedimentation, metamorphism and weathering are all responsible for the forming of the Baozipu iron deposit, consequently, it is an iron deposits of sedimentary-transformd type.
