Classification of Mineral Deposits | Geology for Investors

Felsic. Shallow, Lower Temperature. High silica. Granite, Rhyolite. Tin, REE's, Tungsten, Molybdenum. Although rocks may form at a variety of temperatures and depths within the Earth, they may also be exposed at the surface by erosion, tectonic processes or volcanic eruption. This brings us to our next classification.
