Physical properties
Coarse, uneven-grained gray-green specimen with pale feldspar and darker mineral flecks; typically Mohs 6–7, vitreous to dull, with interlocking crystals and no preferred cleavage as a rock. Exact mineral identification is uncertain from the photo.
Formation & geological history
Granite crystallizes slowly from silica-rich magma deep in the crust, commonly in continental batholiths; its age depends on source and cannot be determined from appearance alone.
Uses & applications
Used as building and paving stone, countertops, monuments, and aggregate; this small rough fragment has mainly educational or modest collecting value.
Geological facts
Granite commonly contains quartz, feldspar, and mica or amphibole; weathering can make feldspar-rich surfaces appear pale or greenish.
Field identification & locations
Look for visible interlocking grains, including glassy quartz and blocky feldspar; common in continental mountain regions and exposed plutons. The image does not allow confident distinction from other coarse crystalline rocks.
