Physical properties

Formation & geological history

Formed by the slow crystallization of magma below Earth's surface. High in potassium feldspar which gives the pink color. Can form in large batholiths over millions of years.

Uses & applications

Used extensively in construction for countertops, floor tiles, and monuments. Also popular as a landscaping stone and for decorative lapidary work.

Geological facts

Pink granite is the state rock of several regions including New Hampshire. The pink color is specifically due to the presence of Orthoclase (potassium-rich) feldspar.

Field identification & locations

Identify in the field by its interlocking crystalline texture (usually quartz, feldspar, and biotite mica) and its overall pinkish hue. Common in mountain ranges and Canadian Shield areas.

Dark Igneous Rock (Likely Basalt or Diabase)

Basalt (extrusive igneous rock) or Diabase (intrusive igneous rock - also known as Dolerite), largely composed of plagioclase feldspar, pyroxene (augite), and sometimes olivine and amphibole. Exact mineralogy would require thin section analysis.
