SC302 - Fluorite, Cerussite


Locality: Blanchard Mine, Bingham, Hansonburg District, Socorro Co., New Mexico, USA (MINDAT)
Size: 12 x 10 x 7 cm - Large cabinet (10-15 cm)
Weight:
minID: DQU-66A

White fluorite cubes covered by secondary lead minerals, mostly (?) cerussite. The cerussite is powdery white, but it covers a translucent mineral which is not (or weakly so) fluorescent. Biggest fluorite cubes are between 8 and 10 mm in size. In the matrix there are some shiny galena cubes, only partially visible. The fluorescence spectra are typical Europium (Eu2+) activated fluorite and for ceruissite.
