Physical properties

Formation & geological history

Formed from the slow cooling of magma deep underground (intrusive) over millions of years, often during the Precambrian or Paleozoic eras. Found in continental crust within batholiths.

Uses & applications

Used extensively in construction for countertops, floor tiles, paving stones, and monuments due to its durability and aesthetic appeal.

Geological facts

The pink color is caused by an abundance of potassium feldspar (orthoclase). Granite makes up the majority of the Earth's continental crust. Famous peaks like Half Dome in Yosemite are composed of granite.

Field identification & locations

Identify by its interlocking crystalline texture where grains are visible to the naked eye. Look for the 'salt and pepper' look with distinct pink patches. Common 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.
