TT48AL5: Group of flattened, twinned crystals, with lattice growths, colorless, transparent, with good luster and small inclusions of Malachite. Of the best quality for a historical locality, especially for its perfection since these specimens are usually very fragile, often have damage, but this piece is nevertheless perfect. The sample comes from the Dick Norris collection (no. 179) whose label, together with a previous one by Dave Bunk, we will send to the buyer.
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.
