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. 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.
Color is blue-green.
Luster is vitreous. Specimens are translucent to transparent. Associated Minerals include other phosphates such as wardite , goyazite , augelite , whiteite , ludlamite , kulanite , lazulite and brazilianite as well as siderite and calcite among others. The Rapid Creek, Big Fish River and Blow River areas, Yukon Territory, Canada and limited examples elsewhere.
