Arsenopyrite from Panasqueira Mines, Portugal
Panasqueira is one of the great European mineral-specimen localities, and arsenopyrite is one of the minerals that gives the mine its unmistakable “look.” The best pieces show bright steel-silver to pale brassy, sharply striated crystals in sculptural clusters, often with the crisp, bladed, spear-like or cock’s-comb habit that makes Panasqueira arsenopyrite recognizable at a glance. Unlike many arsenopyrite localities that yield mostly massive ore or small embedded crystals, Panasqueira has produced free-standing clusters and dramatic combinations where metallic arsenopyrite is staged against milky to clear quartz, books of muscovite, pale to greenish fluorapatite, siderite, pyrite, cassiterite, chalcopyrite, wolframite-group minerals, and topaz.
