Fluorite & Calcite on Gossan
    Santa Eulalia, Chihuahua, Mexico

    On top of many base metal ore deposits is often a zone of intense alteration caused by surface water breaking down sulfide minerals and leaving a cavernous "cap," that German miners call eisenhut: literally an "Iron Hat," because it sits on top of the ore-body. Chiefly formed of iron oxides, these "Iron Hats" or "gossans" as the Cornish miners call the same thing, are often home to cavities filled with strange and sometimes beautiful shapes. The sinuous form of this gossan specimen is rendered in deep black Hematite, with curving lines reminiscent of a charred tree trunk, partially encrusted by frosty white Calcite and accents of tiny, purple Fluorite crystals. High in one of the ore zones, hidden beneath the hills near Santa Eulalia, a miner carefully extracted this dark wonder, knowing that its stark aesthetics would call out to those who value beautiful things. It is in excellent condition.
