2.4 x 1.5 x 2 cm. 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 ... |
