This piece has a vibrant contrast of glassy windowpanes of Yellow Wulfenite surrounded by white Calcite spraying similar to a daisy flower.
Wulfenite is a lead molybdate mineral with the formula Pb(MoO4), prized for its vivid orange-yellow, red-orange, and honey-yellow crystals. Wilhelm Karl von Haidinger renamed it in 1845 to honor Austrian mineralogist Franz Xaver von Wulfen. It typically forms as thin tabular crystals in oxidized zones of hydrothermal lead deposits.
The 79 Mine lies about 1.5 miles west of Chilito and 4.5 miles north-northwest of Hayden in Arizona’s Banner Mining District, where vein and bedding-replacement ores formed chiefly in the Martin Formation and Naco Limestone. Discovered in 1879, this former underground lead-zinc-copper-silver-gold-molybdenum-antimony-vanadium-iron mine produced substantial mixed oxide and sulfide ore, with galena, anglesite, cerussite, and hemimorphite recognized among its principal ore minerals. The locality is especially notable for hemimorphite and for liudongshengite, a mineral first described from the 79 Mine, giving specimens from this historic deposit strong appeal to collectors of Arizona oxidation-zone minerals.
