It is a member of the tsumcorite group. It crystallizes in the monoclinic system and typically occurs as clusters of crystals or granular aggregates.[1][2] It was first described for samples from an abandoned manganese mine in Falotta, Graubünden, Switzerland and named for Swiss amateur mineralogist Walter Cabalzar. It was approved as a new mineral by the IMA in 1997. It has also been reported from the Aghbar mine in Ouarzazate Province, Morocco.[2] References1. ^1 Cabalzarite mineral data from Webmineral {{Commonscat}}{{mineral-stub}}2. ^1 2 Cabalzarite mineral information on Mindat.org 3. ^Brugger J., Meisser N., Schenk K., Berlepsch P., Bonin M., Armbruster T., Nyfeler D. and Schmidt S. 2000: Description and crystal structure of cabalzarite Ca(Mg,Fe,Al)2(AsO4)2(H2O,OH)2, a new mineral from the tsumcorite group.
