Physical properties
Hardness: 6-7 (Mohs). Color: Pink/orange due to orthoclase feldspar, with black biotite and grey quartz crystals. Luster: Vitreous to dull. Phaneritic (coarse-grained) texture.
Formation & geological history
Formed from the slow cooling and crystallization of silica-rich magma deep underground. Most pink granites date from the Precambrian to Paleozoic eras.
Uses & applications
Used extensively in construction for countertops, flooring, monuments, and as crushed stone for road bases.
Geological facts
The pink color comes specifically from the high concentration of potassium-rich orthoclase feldspar. It is one of the most common rocks in the Earth's continental crust.
Field identification & locations
Identify by its interlocking crystalline texture and the presence of salmon-pink feldspar. Found globally in all continental shield areas (e.g., Canadian Shield, Scotland, Brazil).
