Igneous Granite With Feldspar Environment

Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.

Igneous granite with feldspar environment.

Granite is an intrusive igneous rock which means it was formed in place during the cooling of molten rock. Learn more about the properties and uses of granite in this article. Strictly speaking granite is an. The alkali feldspars are primarily.
