Physical properties

Formation & geological history

Formed through the slow cooling and crystallization of molten magma deep beneath the Earth's surface (plutonic formation). It is typically billions to millions of years old, often associated with continental crust formation.

Uses & applications

Extensively used in construction (countertops, floor tiles, paving), monuments, and as crushed stone for road aggregate. Polished specimens are used in decorative architecture.

Geological facts

The pink color is caused by an abundance of potassium feldspar (orthoclase). Granite makes up a large portion of the Earth's continental crust and is one of the hardest natural substances.

Field identification & locations

Look for a interlocking 'salt and pepper' texture with visible pink crystals of feldspar, clear to grey quartz, and dark specks of mica or hornblende. It is found in mountain ranges and glacial deposits.

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.
