About CesiodymiteHide

The Cs (or CsK-) analogue of cryptochalcite. The mineral is doubly-unique being the first Cs sulphate mineral and also the first one to combine Cs and Cu as species-defining elements. It is also the sixth Cs mineral of the oxysalts group (discluding silicate minerals) after caesiumpharmacosiderite (arsenate), londonite, ramanite-(Cs) (borates), margaritasite (vanadate), and mccrillisite (phosphate).

Compare 'Unnamed (Cesium Potassium Sulfate)'.
