Physical properties
Hardness: 6-7 Mohs; Color: Pink, grey, white, and black; Luster: Dull to vitreous; Structure: Phaneritic (coarse-grained) crystalline; Cleavage: Good in feldspar minerals; Specific Gravity: 2.63-2.75
Formation & geological history
Formed by the slow crystallization of magma below Earth's surface. High potassium feldspar content gives it the pink hue. This specimen appears weathered and may be part of a plutonic intrusion or a glacial erratic.
Uses & applications
Extensively used in construction for countertops, monuments, floor tiles, and as crushed stone for road base and landscaping.
Geological facts
Granite makes up a large portion of the continental crust. The pink color specifically indicates a high presence of Alkali (Orthoclase) Feldspar.
Field identification & locations
Identify by its 'salt and pepper' appearance with distinct interlocking crystals of quartz, feldspar, and mica. Check for hardness and resistance to scratching.
