Calcite on Geothite

Goethite is the source for the pigment known as yellow ochre; it is also the primary mineral in some important iron ores, such as those in the Alsace-Lorraine basin in France. Other important goethite deposits are found in the southern Appalachians, U.S.; Brazil; South Africa; Russia; and Australia.

Calcite is the one of the most common minerals. It occurs in a great variety of shapes and colors, and it constitutes a major portion of many of the earth's rocks.
