RB27F8: Dioptase with Wulfenite
From the Mammoth-St. Anthony Mine, no less! A group of Dioptase crystals with great color, on matrix, and with the rare feature of some associated Wulfenite crystals. The St. Anthony deposit is a classic polymetallic carbonate-replacement deposit closely associated with Mesozoic granitic intrusions and low- to medium-temperature hydrothermal systems. The oxidation zone is exceptionally rich and complex, renowned for its remarkable mineralogical diversity and superb secondary species such as Wulfenite, Cerussite, Mimetite, Caledonite, Anglesite, and Linarite. Intense fracturing and deep weathering promoted supergene enrichment, producing colorful assemblages of major historical and mineralogical significance.
