Physical properties
Hardness: 6-7 on Mohs scale. Color: typically white, pink, or gray with dark specks. Luster: dull to shiny (when polished). Crystal structure: coarse-grained, interlocking crystals. Specific gravity: 2.65-2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface. Found in continental crusts worldwide.
Uses & applications
Used extensively in construction as dimension stone, countertops, floor tiles, and monuments.
Geological facts
Granite is the most common plutonic rock of the Earth's crust, forming the core of many mountain ranges.
Field identification & locations
Identified by its visible crystalline structure and lack of foliation. Common in mountainous regions and exposed shields. Look for the distinct speckled pattern of quartz, feldspar, and mica.
