... of the lotharmeyerite subgroup, wherein Me = Ca and X = As. Lotharmeyerite was originally described as CaZnMn 3+ (AsO 4 ) 2 (OH)• 2 H 2 O and was subsequently revised to Ca(Mn 3+ ,Zn) 2 (AsO 4 ) 2 (OH,H 2 O) 2 , but the original and new analyses have shown that Zn > Fe. Therefore, in the general formula Ca(Me) 2...
