| 摘 要： | 福泉磨坊磷块岩矿床是贵州瓮福磷矿的八大矿段之一.主要磷矿层赋存于晚震旦系上统陡山沱组上部,有砂砾状、致密状、团块状及条带状几种矿石类型。矿体厚度品位沿倾向均有线性变化规律;矿体间存在一有相当规模的无矿带,矿石露头局部见磷质叠层石;矿石中磷酸盐矿物以胶磷矿,伴生矿物以白云石为主;碘呈分散状态赋存于磷酸盐矿物中;矿体氧化带深度17～75m,浅部矿石质量优良。矿床成因类型属生物化学沉积的磷酸盐矿床。

| Abstract: | Mofang phosphorite deposit in Fuquan is one of the main ore blocks of Wengfu phosphorite deposit. The major ore bed locates in the Doushantuo Formantion upper Sinian System. There are some ore types, including gritty ore, compact ore, cloddy ore and banded ore. The thickness and grade linear changed across the strike. The dead belt presents between the ore bodies. The phosphate mineral in the ore is cellophane, in which I dispersed and the associate mineral is dolomite. The depth of the oxidation zone is about 17-75meter. The deposit is phosphate biochemical deposit. |
