Wikipedia summary
Adelite
The rare mineral adelite, is a calcium, magnesium, arsenate with chemical formula CaMgAsO_4OH. It forms a solid solution series with the vanadium-bearing mineral gottlobite. Various transition metals substitute for magnesium and lead replaces calcium leading to a variety of similar minerals in the adelite - duftite group.
