安徽省方解石矿床现状分布及类型特征分析

方解石矿为我省特色矿种,资源储量丰富,是我国方解石矿主要产地之一。通过分析,方解石矿主要分布于我省青阳县与泾县两地,占全省储量的91%;其矿床成因类型以接触变质型为主,低温热液充填型次之,两者相比,接触变质型方解石矿矿体规模较大,呈层状、似层状分布,构造简单,矿石质量较好,且稳定,便于开发利用,矿床规模以大中型矿山为主。

DISTRIBUTION,TYPES AND FEATURES OF CALCITE DEPOSITS IN ANHUI PROVINCE

As a characteristic mineral, calcite is abundant in Anhui Province and makes it a major calcite producer in China. Analysis indicated that calcite mainly distributes in Qingyang and Jingxian Counties, taking up 91% of the total reserve of the province. The deposit was formed dominantly by contact metamorphism, secondarily by low-temperature hydrothermal filling. Comparatively, contact metamorphic calcite deposit is big in scale, lamellar, semi-lamellar, and simple in structure, good in quality, stable, easy for development and utilization.
