Lepersonnite-(Gd) is a very rare REE-uranyl carbonate from Shinkolobwe. Here it is intergrown in the yellow Studtite clusters (surrounded by smaller Uranophane xls). The difference is obvious and visible under magnification where the Lepersonnite-(Gd) forms flat crystals while the Studtite forms needles. The orange mineral is Curite. The Shinkolobwe mine is closed since the late 1950’s and is the type locality for all three of these: Lepersonnite-(Gd), Studtite and Curite. This Photo was Mindat.org Photo of the Day - 7th Feb 2010
Fundort: Shinkolobwe Mine (Kasolo Mine), Shinkolobwe, Central area, Katanga Copper Crescent, Katanga, Demokratische Republik Kongo (Fundort bei mindat.org)
La lepersonnite est enchevêtrée dans les agrégats jaunes de studtite (entourés par des cristaux d'uranophane plus petits). Sous le microscope on voit nettement que la lepersonnite forme des cristaux plats tandis que la studtite forme des aiguilles. Le minéral orange est de la curite.
Localité : zone centrale de la mine de Shinkolobwe (province du Katanga, République démocratique du Congo).
Taille : 2,4 x 1,5 x 2 cm.
