A contact-metamorphic occurrence of the assemblage nepheline-scapolite-diopside in a metabasic flow breccia from Bergslagen, Sweden

Lead isotope systematics in the Långban deposit and adjacent sulphide mineralisations in western Bergslagen, Sweden

“…Contact metamorphism related to several stages of intrusive activity (e.g. Lundström & Papunen 1986;Rickard 1988;Lundström 1995;Allen et al 1996) is locally important (Hellingwerf 1985;Björk 1986). Post-peak Svecokarelian retrograde alteration evident in the Långban area may be the result of thermal input from the Hyttsjö and Filipstad intrusives, and is estimated to have reached temperatures of around 3008C (Magnusson 1930;Björk 1986;Grew et al 1996).…”
