Sulphosalt, chalcostibite group
Specific gravity: 6.38
Colour: Greyish to tin-white
Emplectite is a rare sulphosalt formed at medium temperatures in hydrothermal veins with other sulphides and sulphosalts
At Horní Slavkov, Sokolov District, Karlovy Vary Region, Czech Republic, emplectite is associated with chalcopyrite, pyrite, sphalerite, molybdenite, quartz and fluorite (HOM).
At the Clara Mine, Oberwolfach, Ortenaukreis, Freiburg Region, Baden-Württemberg, Germany, although emplectite is rare, crystals have been found, exceptionally up to 1 cm in size. Associated minerals include bariopharmacosiderite, scorodite, fluorite and baryte, as well as secondary beyerite and bismutite (R&M 90.1.43).
The type locality is the Tannenbaum mine, Antonsthal, Breitenbrunn, Erzgebirgskreis, Saxony, Germany.
From Johanngeorgenstadt, Erzgebirgskreis, Saxony, Germany, a specimen has been found with emplectite, in some cases partly filmed with limonite, in association with quartz and chalcopyrite (AM 18.277).
At Kairagach Au deposit, Okhangaron District, Tashkent, Uzbekistan, emplectite is associated with tetrahedrite–tennantite, luzonite–famatinite, pyrite, mawsonite, nekrasovite, chalcopyrite, laitakarite, bismuth, calcite, quartz and baryte (HOM).
