一、矿床基本情况 浏阳磷矿是以白云质磷块岩为主的浅海浅变质沉积矿床。产于震旦—寒武系地层中。矿区系一向南倾斜的倒转单斜构造,矿体顶部为板溪群板岩,底部为石炭系壶天灰岩。矿区断裂、褶曲发育,矿体呈层状、似层状、透镜状的矿群产出。单个矿体厚度由1～57米不等,倾角由10～85°,一般为40～5°。矿体出露地表最高为180米,一般为130米。向下一般控制到-100米,局部最深达-200米。矿体向深部厚度变薄,品位变贫。 矿区累计提交地质储量Ⅰ级品3000多万
First, the basic situation of the deposit Liuyang phosphate rock dolomite is mainly composed of shallow marine shallow metamorphic sedimentary deposits. Produced in Sinian - Cambrian strata. The mining area has a south-reverse inverted monocline structure. The top of the orebody is Banxi Group slate and the bottom is Carboniferous Hu Tian limestone. Mining area rupture, fold development, the ore body is layered, stratified, lens-like output of the mine group. The thickness of a single ore body ranging from 1 to 57 meters, angle from 10 to 85 °, usually 40 ~ 5 °. Ore body surface exposed up to 180 meters, usually 130 meters. Down to the general control of -100 meters, the deepest up to -200 meters. The ore body to the deep thinning, poor grade. The mine has submitted a total of more than 30 million Grade I geological reserves
