Strata-bound scheelite mineralisation in skarns and gneisses from the Bindal area,Northern Norway

Scheelite in the Bindal area, Northern Norway, is developed in hornblende-biotite gneisses of volcano-sedimentary origin, especially in the zones of disseminated sulphides in the gneisses. Scheelite is present either in mobilised quartz veins or in skarnitised hornblende-biotite gneiss where limestone was in contact with these rocks. An exhalative-sedimentary origin of the mineralisation is proposed, on account of the strata-bound character and the lack of any direct relationship to the plutonic rocks of the Bindal massif.
