摘　　要：湖北省咸丰县清坪矿区优质饰面用大理岩矿赋存于下三叠统大冶组四段上亚段(T_(1)d^(4-2)),呈层状、似层状产出,厚度稳定。文章主要对该区饰面用大理岩的矿体特征、矿石质量特征和矿体节理裂隙发育情况等方面进行了阐述。该大理岩矿床为中型规模,矿体形态完整、边界规则,厚度变化属稳定型,矿石结构简单,矿石的物理机械性能均满足饰面石材一般工业指标要求。根据目前市场行情,矿区饰面用大理岩属于中—高档饰面石材,具有较好的开发利用价值。The high-quality facing marble orebody in Qingping mining area of Xianfeng County,Hubei Province is hosted in the upper sub-member of the fourth member of Lower Triassic Daye Formation (T_(1)d^(4-2)).It is produced in a layered and quasi-layered shape with stable thickness.This paper mainly expounds the orebody characteristics,ore quality characteristics and joint-fissure development in the facing marble in this area.The marble deposit is medium-sized,with complete orebody shape,regular boundary,stable thickness variation,simple ore texture,and the physical and mechanical properties of the orebody meet the general industrial index requirements of facing stone materials.According to the current market situation,the marble for facing stone in this area belongs to medium to high grade type,which has the good development and utilization value.
