Chlorite rock sample. Chlorite is a green, elongated mineral often found in metamorphic rocks. Its presence indicates high pressures and temperatures during processes such as orogeny (mountain-building), in this case the collision of Africa and Europe during the formation of the Alps. This sample is from the Matterhorn, Zermatt, Switzerland.
