Short summary
Belmonteite, CaMn2(AsO4)2(H2O)5·2H2O, is a new mineral discovered in the Mn ore deposits of eastern Liguria (Italy). Its crystal structure shows {010} layers of six-fold-coordinated Mn atoms decorated on both sides by (AsO4) groups and Ca atoms and connected through H bonds. The genesis of this mineral is related to the circulation of As-rich oxidizing fluids within the Mn ore deposits. The name honors Donato Belmonte for his contribution to the knowledge of the mineralogy of Liguria.
