Physical properties
Hardness of 6 on the Mohs scale, predominantly red to pink with white and black flecks, vitreous luster, and a coarse-grained phaneritic texture.
Formation & geological history
Formed from the slow crystallization of magma beneath the Earth's surface over millions of years.
Uses & applications
Widely used in dimensional stone, architectural building facades, monuments, countertops, and paving materials.
Geological facts
The red coloration is primarily due to an abundance of potassium feldspar (orthoclase) within its mineral matrix.
Field identification & locations
Identify in the field by its interlocking visible crystals of pink feldspar, quartz, and dark biotite mica; common globally in continental shields.
