Follow-up studies in the Okstindan Area, The Rødingsfjall Nappe Complex, Nordland, Norway
Follow-up work has been conducted in three restricted areas of the 1200 km2 large Okstindan Area on the basis of earlier anomalies found during regional surveys. The three areas have been subjected to detailed geophysical mapping, mineralogical studies and sampling for whole-rock geochemistry. Miner...

Mineralizations in the area consist of non-economic sulfide-impregnations with restricted thickness and extent. Skarn-type mineralizations consisting of mainly clinoamphibole, garnet, quartz and biotite, found in the Brunesbekken and Grasvatnet areas, have not previously been reported from the Okstindan Area.
