Physical properties
Hardness: 6-7 Mohs; Color: Pink, white, and black mottled; Luster: Vitreous to dull; Structure: Phaneritic (coarse-grained); Composition: Quartz, Feldspar (Orthoclase), and Biotite mica.
Formation & geological history
Formed from the slow crystallization of silica-rich magma below Earth's surface. This specimen likely dates from the Precambrian to Cenozoic eras depending on specific locality.
Uses & applications
Extensively used in construction, countertops, monuments, curbing, and as decorative crushed stone for landscaping.
Geological facts
The pink color is specifically due to the high concentration of potassium feldspar (orthoclase). Granite makes up much of the Earth's continental crust.
Field identification & locations
Identify by its interlocking crystalline texture and visible grains of pink feldspar and clear quartz. Commonly found in mountainous regions or glacial till.
