How does volcanic tuff form

Tuffs have the potential to be deposited wherever explosive volcanism takes place, and so have a wide distribution in location and age. Rhyolite tuffs contain pumiceous, glassy fragments and small scoriae with quartz, alkali feldspar, biotite, etc. Iceland, Lipari, Hungary, the Basin and Range of the American southwest, and New Zealand are among the areas where such tuf… WebAndesite is the name of a family of fine-grained, extrusive igneous rocks that are usually light to dark gray in color.

WebIgneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.
