| Title: | Structural aspects of some gold mineralizations in the Skellefte District, northern Sweden / Ulf Bergström, Pär Weihed. |
| Author(s): | Bergström, Ulf. Weihed, Pär. |
| Date: | 1991. |
| In: | Geologiska Föreningens i Stockholm Förhandlingar. (1991.), Vol. 113(1) (1991) |
| Abstract: | Discusses structural control on some of gold deposits, on both regional and deposit scale. Subdivides Lower Proterozoic rocks into different palaeotectonic settings. Gold mineralizations postdate main deformation and are syn- to post-metamorphic. On deposit scale, most are related to quartz veins and/or alteration aureoles, sulphide dissemination, and ductile to brittle faults and shear zones. Primitive nature of porphyries indicates probable origin in upper mantle or lower crust. Suggests tentatively that gold originated from magmatic and/or metamorphic fluids. |
