湖北锰矿成矿规律与开发利用前景

在总结前人资料的基础上，对比华南地区锰矿地质特征，将湖北锰矿床按成因划分为四大类：正常沉积类、沉积变质奖、沉积热液改造类、表生风化类。岩相古地理沉积环境是湖北锰矿最重要的控矿因素。沉积成矿作用是最基本的成矿作用。成矿规律与各地史时期的沉积环境、构造运动、岩浆侵入喷发密切相关。锰矿资源特点是：以沉积型锰矿为主，矿床规模不大；矿石以贫矿为主，含磷高；工作程度低，开发利用率低，市场需求缺口大，前景看好。

MANGANESE DEPOSITS IN HUBEI PROVINCE:METALLOGENIC LAW, PROSPECTS OF DEVELOPMENT AND UTILIZATION

Manganese deposits in Hubei can be divided into four genetic types that are normal sedimentary type, sedimento-metamorphic type, sedimento-hydrothermal type and supergene weathering type. The lithofacies-paleogeographical environment is the most important ore-control factor. The basic mineralization is sedimentary mineralization and the metallogenic law is closely related to sedimentary environment, tectonic movement and magmatic intrusion or eruption in various geohistoric ages. In Hubei, the sedimentary manganese deposit is the major type with small scale, low grade and high phosphorus content. The exploration, development and utilizaton of manganese deposits in Hubei are of lower level but have a good prospects.
