http://www.mindat.org/min-39217.html There are three photos posted of this mineral all completely different looking. I am wondering if two of these aren't something else since they could be easily confused with nickelaustinite or even annabergite. Does anyone know which one is closest in appearance to the type specimen?
I believe this habit http://www.mindat.org/photo-432655.html is closest to the type-description: "nickeltalmessite Ca2Ni(AsO4)2*2H2O has been found in association with annabergite, nickelaustinite, pecoraite, calcite and a mineral of the chromite-manganochromite series on a dump of the Ait Ahmane mine (Bou Azzer district, Marocco). The new mineral forms botryoidal aggregates consisting of split individuals up to 10 *10 * 20 mkm in size. Color is apple-green, streak white." ( http://rruff.info/rruff_1.0/uploads/ZRMO138_32.pdf )
