Summary

[edit]
Description

Granite in the Precambrian of Ontario, Canada.

Granite is the number one most common rock in Earth's continental crust. It is a felsic, crystalline-textured, intrusive igneous rock. Granite must contain quartz and potassium feldspar. Other minerals commonly included in granite are sodic plagioclase feldspar, amphibole, and mica.

The granite outcrop seen here is part of the Cartier Granite, a 2.6 billion year old intrusion in Ontario. The granite's texture at this site is phaneritic (= coarsely-crystalline).

Geologic unit: Cartier Granite, Algoma Plutonic Complex, Neoarchean, 2.642 Ga
