Physical properties
Hardness of 6-7 on the Mohs scale, colors ranging from pink to gray depending on feldspar content, vitreous to dull luster, granular phaneritic crystal structure, specific gravity around 2.65 to 2.75.
Formation & geological history
Formed from the slow cooling and crystallization of magma rich in silica and alkali metal oxides beneath the Earth's surface.
Uses & applications
Widely used in construction, countertops, monuments, and architectural facings due to its durability and aesthetic appeal.
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. Found globally in major mountain ranges and continental shields.
