Stekenjokk

概述

Massive, dissemination, 2-10 m thick, extremely elongate shape, slightly oblique to the generally NNW axial direction of the F2 folds. Disseminated ore beneath the massive ore is irregular and pyrrhotite-rich, may be the feeder zone. Stratigraphy may be inverted. Contains 18.76% S. Remobilization. Rifted ensimatic island arc (immobile trace elements indicate a mixture of mildly tholeiitic island arc volcanites and strongly tholeiitic to alkaline rifting-type basalts), thought to have formed in an incipient intra-arc rift.
