Physical properties
Hardness of 6-7 on the Mohs scale, speckled pink, white, and grey color, dull to vitreous luster, phaneritic crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow cooling and solidification of magma rich in silica and alkali feldspar deep beneath the Earth's surface over millions of years.
Uses & applications
Widely used in construction, architectural building facades, countertops, and monumental stone due to its exceptional durability.
Geological facts
Granite is the principal component of the continental crust and constitutes many famous mountain ranges like the Sierra Nevada.
Field identification & locations
Easily identified by its interlocking visible mineral grains of quartz, feldspar, and mica. Found globally in continental shields.
