摘要
华宁红坡磷矿呈层状赋存于寒武系下统渔沪村组第三段.矿石工业类型简单,以硅质及硅酸盐型为主,次为混合型.地表及浅部垂向上矿石品级呈Ⅰ+Ⅱ至Ⅲ+Ⅳ分布;深部矿层垂向上矿石品级总体呈Ⅲ至Ⅰ+Ⅱ至Ⅲ分布.含矿层中非矿部分及表外矿多分布在工业矿体的上面及下面,工业矿体(Ⅰ-Ⅲ品级)垂向连续稳定.矿区位处华宁陆表海,属昆明-华宁聚磷盆地东侧,为早寒武世海相沉积型层状磷块岩矿床.
Abstract
The Hongpo phosphate deposit in Huaning is layered in the third member of the Lower Cambrian Yuhucun Formation.The ore industrial type is simple,mainly siliceous and silicate type,followed by mixed type.The ore grade of the surface and shallow part is distributed from Ⅰ+Ⅱ to Ⅲ+Ⅳ in the vertical direction.And the ore grade in the deep part is generally distributed from Ⅲ to Ⅰ+Ⅱ to Ⅲ.The non-ore part of the ore-bearing layer is mostly distributed above and below the industrial ore body,and the industrial ore body(grade Ⅰ-Ⅲ)is vertically continuous and stable.It is an Early Cambrian marine sedimentary layered phosphorite deposit.
