Physical properties
Hardness of 6 on the Mohs scale, predominantly red to pink color with black flecks, vitreous luster, phaneritic crystal structure, and specific gravity around 2.65.
Formation & geological history
Formed through the slow, underground cooling of silica-rich magma over millions of years.
Uses & applications
Widely used in construction, architectural monuments, countertops, and decorative stone.
Geological facts
Red granite gets its characteristic pink and red hues from an abundance of potassium feldspar during crystallization.
Field identification & locations
Easily identified by its interlocking visible grains of quartz, feldspar, and biotite mica; commonly found in continental shields worldwide.
