Title
A name given to the resource
(PH) Powderhorn (Iron Hill) Carbonatite Suite -- Gunnison County, SW Colorado
Description
An account of the resource
The Powderhorn (Iron Hill) Carbonatite is located in Gunnison County in about the center of the southwestern quadrant of Colorado. It is a pear-shaped body which is essentially conical at depth, and is exposed over an area of about 12 square miles. The carbonatite body covers about 2 and a half square miles; About 70 percent of the in pyroxenite which was subsequently intruded by or replaced by nepheline and melilite-bearing rocks; magnetite-perovskite, and carbonatite.
