Petrological characteristics of the granitic building stone in the Mungyeong-Sangju area
Abstract
The light pinkish granite (LPG) and pinkish granite (PG) distributing widely in the Mungyeong-Sangju area are characterized by miarolitic texture of various shape and size. By the joint frequency contour diagram, the joints of orthogonal thpe are recognized in the LPG and PG. From the petrologic textures, joint pattern, and joint spacings, it is recommended that the LPG has more possibility than the PG in recovery ratio of stone. The average physical properties such as specific gravity, absorption ratio (%), porosity (%) and compressive strength (kg/
