Physical properties
Hardness of 6-7 on the Mohs scale, colors range from pink to gray depending on feldspar content, dull to vitreous luster, phaneritic (coarse-grained) crystal structure, specific gravity around 2.65-2.75.
Formation & geological history
Formed from the slow cooling of magma rich in silica and alkali metal oxides beneath the Earth's surface, typically occurring over millions of years during continental orogenic events.
Uses & applications
Widely used in construction, architectural facades, monument building, countertops, and decorative stone due to its durability and aesthetic appeal.
Geological facts
Granite makes up a major part of the continental crust and is one of the most durable natural building materials known to humanity.
Field identification & locations
Easily identified in the field by its interlocking visible crystals of quartz, feldspar, and mica. Found globally in major mountain ranges and shields.
