Physical properties
Pink-gray, rough and granular, with visible interlocking mineral grains; typically Mohs 6–7, vitreous quartz and feldspar luster, and no prominent cleavage at the rock scale. The photograph is consistent with granite, though exact identification requires closer examination.
Formation & geological history
Forms when silica-rich magma cools slowly underground, allowing crystals to grow; granite bodies occur across many geologic ages, commonly in continental crust.
Uses & applications
Used for building stone, paving, countertops, monuments, and decorative aggregate; this small specimen is mainly suited to collecting.
Geological facts
Pink color commonly comes from potassium feldspar, while dark flecks are often biotite or amphibole.
Field identification & locations
Look for a speckled, interlocking mix of light quartz/feldspar and darker minerals; common in continental mountain belts and exposed plutons. A hand lens can help distinguish granite from similar rocks.
