What is "satterlyite"

n. (context mineralogy English) A trigonal-ditrigonal pyramidal mineral containing hydrogen, iron, magnesium, oxygen, and phosphorus.

Satterlyite is a hydroxyl bearing iron phosphate mineral. The mineral can be found in phosphatic shales and was first discovered in the Big Fish River area in Yukon Territory, Canada.

Satterlyite is part of the phosphate mineral group. Satterlyite is a transparent, light brown to light yellow mineral with a density of 3.68 g/cm. The structure of satterlyite is made up of two pairs of face shared, distorted (Fe,Mg)O octahedra, linked together by sharing edges to form double chains along the [001] plain.

The first satterlyite mineral was discovered in the Big Fish River area in Yukon Territory, westernmost of Canada; by a geologist at Ontario Department of Mines in Canada, Jack Satterly, and the mineral was also named after him (Kolitsch, 2002).
