Physical properties

Formation & geological history

Formed from the slow crystallization of magma below the Earth's surface. Rich in potassium feldspar which gives the pink hue. Most specimens date back hundreds of millions to billions of years.

Uses & applications

Extensively used in construction as countertops, flooring, monuments, and decorative stone in landscaping. High durability makes it ideal for public buildings.

Geological facts

Granite makes up a large part of the Earth's continental crust. Its pink color specifically indicates a high presence of orthoclase feldspar.

Field identification & locations

Identify by its interlocking crystalline texture and pink/salmon color. Commonly found in mountainous regions or glacial deposits. Look for a 'salt and pepper' look combined with pink tones.

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.
