...Halil Sarp; Radovan Cerny Abstract Yvonite, Cu(AsO 3 OH)2H 2 O, was found in the Salsigne mine near Carcassone (Aude, France). It forms aggregates or radiating spherules consisting of individual crystals (maximal size 0.3X0.15X0.06 mm) of turquoise blue color. They are elongated in c, flattened...

Normal anhydrous Cu 2+ arsenate is known as the naturally occurring species lammerite [Cu 3 (AsO 4 ) 2 ], but it is very rare ( Anthony et al. 2000 ). Similarly, yvonite [CuHAsO 4 ·2H 2 O] is known from only...
