Gormanite is one of the new phosphates coming from the hydrothermal
phosphate deposits such as the Rapid Creek, Big Fish River and Blow River
areas in the Yukon Territory of Canada. Gormanite forms a series with the
A series is a set of minerals that differ only in their chemical content and not appreciably in their respective structures. The chemical difference is usually between two elements that can occupy the same site in a crystal lattice and thus can substitute for each other. If the substitution can range from 100% of element A to 100% of element B in the site, then the series is called a complete series. In this case, the series is probably incomplete between the magnesium rich souzalite and the iron rich gormanite.
Gormanite is relatively new to the mineral world having been described in just the last 20 years. Gormanite forms attractive, colorful specimens with generally good crystals that are easily a good addition to anyone's collection.
