AB The Skellefte Mining District is located in the northern Sweden, in an early Proterozoic (1.90-1.87 Ga)volcanic arc province in the Baltic Shield. It is composed by a complex submarine volcanosedimentarysuccession named Skellefte Group overlain by shallow- to deep-marine sedimentary rocks and maficvolcanics named the Vargfors Group, at the top occurs a subaerial felsic volcanic succession named theArvidsjaur Group (Allen et al., 1996). Among the intrusions in the area, the Jörn Granitoid Complex (JGC)and the Viterliden Intrusive Complex (VIC) are the most significant and crops out in the central andwesternmost area of the Skellefte district respectively. Both complexes emplaced at similar ages and igneousrocks are similar in bulk composition. Also, they show similar relationships with the Skellefte volcanics, asin both cases early plutonic phases are coeval with volcanics whereas late plutonism postdates the Skelleftegroup. In contrast, JGC and VIC markedly differ in deformation and metamorphic style. We show that themetamorphism in the JGC is mainly static, whereas the VIC is related to regional deformation producingintense ductile deformation. Also, a number of mineral phases, including amphiboles, distinctly differ incomposition from the Jörn to the VIC area. We conclude that metamorphism in the VIC and the JGCoccurred in contrasting tectonic settings
