Tellurides, selenides and associated minerals in the Tunaberg copper deposits, SE Bergslagen, Central Sweden (original) (raw)
Summary
The Tunaberg copper deposits, SE Bergslagen, Central Sweden, locally contain tellurium and selenium minerals not previously reported from this locality. Hessite, tellurobismutite, tellurium, tetradymite, kawazulite, clausthalite and selenian galena are found as inclusions in bornite and chalcopyrite in a skarn sulphide ore with Cd-rich sphalerite, cobaltite and cobalt pentlandite (assemblage A), and in a skarn iron ore with magnetite (assemblage B). Accessory minerals included in bornite and chalcopyrite are auriferous silver, electrum, carrollite, stannoidite, mawsonite, parkerite, aikinite, emplectite, wittichenite and two unidentified Cu-Ag-Bi sulphosalts.
The tellurides, selenides and associated minerals in assemblage A occur, in part, as early crystallites and, in part, as segregations from a high-temperature bornite solid solution, which presumably crystallized from metamorphogenic skarn-forming ore solutions, about contemporaneous with the formation of diopside above 475°C and of retrogressive tremolite above 420°C. Minerals of Bi-Te-Se-Pb-Ag in assemblage B presumably crystallized at lower aS2 and higher aCu+ from residual hydrothermal solutions of similar metamorphogenic origin.
Zusammenfassung
Die Kupferlagerstätten von Tunaberg, SE Bergslagen, Zentral-Schweden enthalten stellenweise Tellur-und Selen-Minerale, die hier bisher nicht bekannt waren. Hessit, Tellurobismutit, gediegen Tellur, Tetradymit, Kawazulit, Clausthalit und selen führender Bleiglanz kommen als Einschlüsse in Bornit und Kupferkies in einem Skarn-Sulphiderz mit cadmiumreichem Sphalerit, Cobaltit und Cobalt-Pentlantit (Paragenese A), und in einem Eisenskarnerz mit Magnetit (Paragenese B) vor. Akzessorische Minerale in Bornit und Calcopyrit sind goldführendes Silber, Electrum, Carrollit, Stannoidit, Mawsonit, Parkerit, Aikinit, Emplektit, Wittichenit und zwei noch nicht identifizierte Cu-Ag-Bi Sulphosalze.
Die Telluride, Selenide, und assoziierte Minerale in der Paragenee A kommen teils als frühe Kristalliten und teils als Segregationen aus einer Hoch-Temperatur Bornit-“solid solution” vor, die auf metamorphogene skarnbildende Erzlösungen zurückgehen. dürfe. Diese Vorgänge fallen zeitlich mit der Bildung von Diopsid oberhalb von 475°C und von retrogradem Tremolit oberhalb von 420°C zusammen. Bi-Te-Se-Pb-Ag-Minerale der Paragenese B kristallisierten bei niedrigerem aS2 und höherem aCu+ aus residualen hydrothermalen Lösungen metamorphen Ursprunges.
