摘要
研究区位于湖北随县北部,区内出露的震旦系上统尚家店组厚层大理岩,具有一定的饰面石材开发利用前景。大理岩主要化学成分CaO(24.88%~30.48%)、MgO(19.23%~22.39%)、SiO_(2)(0.29%~21.78%);压缩强度61MPa~98MPa,抗折强度2.2MPa~26.2MPa,镜像光泽度63°~86°,耐磨性14.4cm^(3)~25.6cm^(3),天然密度2.77g/cm^(3)~2.84g/cm^(3),吸水率0.13%~0.227%。体图解荒料率为42.02%~51.03%。
The study area is located in the northern part of Suixian County,Hubei Province.The thick marble of Shangjiadian Formation of Upper Sinian system exposed in the area has certain prospects for the development.The main chemical components of marble are CaO(24.88%~30.48%),MgO(19.23%~22.39%),SiO_(2)(0.29%~21.78%);compressive strength 61~98 MPa,flexural strength 2.2 MPa~26.2 MPa,mirror gloss 63°~86°,wear resistance 14.4 cm^(3)~25.6 cm^(3),natural density 2.77 g/cm^(3)~2.84 g/cm^(3),water absorption rate 0.13%~0.227%.The block yield is 42.02%~51.03%.
