Abstract

The Juomasuo and Hangaslampi Au-Co deposits are hosted by the Paleoproterozoic Kuusamo belt in northeastern Finland. Sulphur isotope and trace element data from sulphides indicate that the geochemically distinct, Au-Co and Co-only enrichments were formed from fluids of different origin. Accordingly, sericite alteration is typical in the zones of the Au-Co enrichment, whereas the chlorite-biotite-amphibole alteration occurs in relation to the Co-only mineralization. Variation in the composition of host rocks does not seem to have a strong control on the type of mineralization.
