Abstract

This paper investigates the deposit geology, ore body characteristics, and ore characteristics of the ornamental granite mine located in Xinyi, Guangdong Province. According to the research, ornamental granite is mined in the Silurian period at an elevation of +943m~+423m. The ore is composed primarily of gneissic granite, and the principal constituent minerals are potassium feldspar, plagioclase, quartz, and biotite; potassium feldspar accounts for 25%~30%, plagioclase for 30%~35%, quartz for 30%~35%, and biotite for 7%~9%; the principal chemical components are SiO₂ and Al₂O₃, accounting for 68.15% and 13.29%, respectively. The density is 2.61~2.69g/cm³, the water absorption rate is 0.09~0.19%, the abrasion resistance is 66~119cm^-3, the bending resistance is 13.5~18.3MPa, the gloss is 87.0%~87.7%, the dry compressive strength is 82.5~141.0MPa, the saturated compressive strength is 71.0118.0MPa, the internal irradiation index is I_Ra=0.1, and the external irradiation index I_r=0.3～0.4，which can meet the decoration and construction purposes.
