Physical properties

Hardness of 6 on Mohs scale, typically pink, white, or gray with speckled appearance, dull to sub-vitreous luster, phaneritic crystal texture, specific gravity around 2.65.

Formation & geological history

Formed from the slow cooling of silica-rich magma beneath the Earth's surface, often during mountain-building events in continental crust.

Uses & applications

Widely used in construction, monument building, countertops, and architectural facing stone due to its durability.

Geological facts

Granite is the most common rock of the Earth's continental crust and is exceptionally resistant to weathering.

Field identification & locations

Easily identified by its visible interlocking crystals of quartz, feldspar, and mica. Common in shield areas and mountainous regions globally, highly consistent with the East African region.
