Pink granite (likely weathered granite)
Granite; mainly quartz, alkali feldspar, plagioclase, and minor mica
AI-generated identification · may be incorrectCoarse-grained, pale pink and white with granular texture and dull-to-glassy luster; hardness about 6–7 Mohs, no strong cleavage as a rock, and specific gravity about 2.6–2.7.

Physical properties
Coarse-grained, pale pink and white with granular texture and dull-to-glassy luster; hardness about 6–7 Mohs, no strong cleavage as a rock, and specific gravity about 2.6–2.7. The image suggests weathering or surface staining, obscuring individual crystals.
Formation & geological history
Intrusive igneous rock formed when silica-rich magma slowly crystallized deep in the crust, commonly during Precambrian to Phanerozoic mountain-building events. Weathering has rounded and roughened the exposed specimen.
Uses & applications
Widely used as dimension stone, countertops, monuments, paving, aggregate, and landscaping rock; attractive pieces are collected but usually have modest value.
Geological facts
Pink color commonly comes from potassium-rich feldspar, while translucent grains may be quartz. Granite is one of Earth’s most abundant continental crust rocks.
Field identification & locations
Identify it by interlocking visible crystals of pink feldspar, gray/translucent quartz, and dark mica; a glassy quartz grain will not scratch readily with a steel knife. Common worldwide, especially in continental shields and mountain belts.
