Physical properties
Hardness: 6 to 7 on Mohs scale; Color: Mottled pink with white, grey, and black specks; Luster: Phaneritic (crystalline) and somewhat dull when unpolished; Crystal Structure: Granular/Coarse-grained; Specific Gravity: 2.63 - 2.75
Formation & geological history
Formed through the slow crystallization of magma below the Earth's surface (intrusive). The pink color is derived from a high potassium feldspar (orthoclase) content. It can be found in continental crust spanning billions of years to more recent tectonic events.
Uses & applications
Used widely in construction for countertops, floor tiles, and gravel. Also used for monuments, sculptures, and as a durable building facade material.
Geological facts
Granite is one of the hardest and most common rocks in the Earth's continental crust. Its name comes from the Latin word 'granum', meaning a grain, in reference to its coarse-grained structure.
Field identification & locations
Identify in the field by its interlocking mineral grains (quartz, feldspar, and mica). It lacks any layering or foliation. Commonly found in mountain ranges and eroded continental shields.
