Formation & geological history
Formed from the slow crystallization of magma below Earth's surface. Intrusive igneous rock.
Uses & applications
Used in construction, monuments, paving, and occasionally collected by hobbyists.
Geological facts
The distinct white band is a quartz or pegmatite vein that intruded into the cooling granite.
Field identification & locations
Recognizable by its granular texture containing feldspar, quartz, and mica. Commonly found in continental crust terrains.
