Sabugalite on Autunite
Margnac Mine, Compreignac, Haute-Vienne, Limousin, France
Miniature, 3.3 x 2.8 x 2.8 cm
An extremely rare uranium phosphate, with crystals completely covering a knoll of matrix (partly autunite). This is very rich and colorful, and I believe is quite good for the locality. I have seen only a few sabugalites from Brazil and France before, of which this is the richest I have personally handled.
