摘要
廖河大理石矿床是近年来安徽省宿松县新发现的大型大理石矿床,矿体主要赋存于下元古界宿松群大新屋组上段,主要岩性为白云石大理岩。在分析矿区地质资料的基础上,结合野外地质调查及样品测试分析结果,系统讨论了矿区地质特征、矿床地质特征以及矿石主要工艺性质。研究表明:(1)矿床(体)分布严格受地层层位控制,矿体围岩主要为白云石英片岩,其产状与矿体产状基本一致,矿石类型包括白云石大理岩、含石英白云石大理岩和含方解石白云石大理岩;(2)矿石基本物理特征参数、荒料率、加工性能与出材率均满足饰面石材工业技术标准,矿床开采技术条件较好,矿石加工技术性能优良,具备了良好的开发前景。
Liaohe marble deposit is a large marble deposit that is found in Susong County,Anhui Province in recent years. The ore-bodies are mainly distributed in the upper of Daxingwu Formation of Lower Proterozoic Susong Group,it is mainly composed of dolomite marble. Through the analysis of geological data of the mining area,based on the field geological investigation results and ore samples test data,the geological characteristics of mining area and deposit are discussed systematically,besides that,the ore process property is also studied. The stduy results show that：（1）the distribution of ore-bodies are mainly controlled by stratigraphic position,surroudning rock of ore-body is mainly composed by muscotite schist,which occurrence characteristics is consitent to the one of ore-bodies,the ore types include dolomite marble,quartz dolomite marble and calcite dolomite marble;（2）the basic physical characteristics,stoneblock rate,processing performance and outturn percentage of the ores can basically meet the industrial techncial standard facing stone,besides that,the mining technical conditions of the deposit is good,technical performance of ore processing is excellent,therefore,the utilization prospect of the deposit is good.
