摘　　要：贵州瓮(安)福(泉)磷矿(以下简称瓮福磷矿)地处上扬子东缘成矿带西南端的黔中成磷区,为超大型海相沉积磷块岩矿床,含磷岩系为震旦系下统陡山沱组,已勘查面积约120 km^2,探获磷矿资源总量达37.9亿吨。通过研究瓮福磷矿地质特征,分析早震旦世陡山沱期古地理环境及岩相分布、陡山沱组含磷岩系分布及其岩性组合、构造保存条件,初步划定面积达800 km^2范围的瓮福磷矿远景预测区,根据控制磷矿产出的各要素特征,已有工程的揭露情况,对远景区找矿潜力作了预测。Weng’an-Fuquan phosphorite deposit(Wengfu phosphorite deposit for short)of Guizhou is situated in central Guizhou phosphorite metallogenic area of Hubei-Hunan-Guizhou metallpgenic area,it is a super large marine sedimentary phosphorite deposit,the phosphorite rock series is Doushantuo formation of Lower Sinian system,the explored area is 120 km^2,the total phosphorite resource is 3.79 billion ton.By study the geological characteristics of Wengfu phosphorite deposit,the paleogeographic environment in Doushantuo period of early Sinian,litofacies distribution,phosphorite bearing rock series distribution in Doushantuo formation,its litofacies assemblage and the structural preservation are analyzed,then the Wengfu phosphorite prospecting area of 800 km^2 delimited preliminarily.According to each factor features which control the phosphorite outcome and exposed condition of finished project,the prospecting exploration potential are predicted.
