Physical properties
Hardness: 6-7 Mohs; Color: Pink, reddish-orange with grey and black specks; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse crystals); Cleavage: Perfect on feldspar grains; Specific gravity: 2.63-2.75
Formation & geological history
Formed through the slow cooling and crystallization of silica-rich magma deep within the Earth's crust (plutonic). Found in continental crust formations, often billions of years old.
Uses & applications
Used widely in construction as dimension stone, countertops, floor tiles, monuments, and as crushed stone for road aggregate.
Geological facts
The pink color is due to the presence of potassium feldspar (orthoclase). It is one of the most common rocks on the Earth's continental crust and is exceptionally durable against erosion.
Field identification & locations
Identify by its interlocking coarse crystals and distinctive pink/red color mixed with translucent quartz. Commonly found in mountain ranges and glacial deposits.
