En sulfidförande kvartsgång vid Unna Järta sydväst om Kebnekaise

Abstract The Unna Järta sulphide occurrence is situated on the SE slope of the mountain Unna Järta near the Kebnekaise Massif and 80 km W of Kiruna. The occurrence consists of a sulphide-bearing quartz-vein about 1 m wide and at least 400 m long. The vein lies in a flexure, at the contact of allochthonous and autochthonous Caledonian rocks. The most common sulphide mineral is pyrrhotite but locally concentrations of sphalerite and silver-bearing galena are found.
