A geochemical investigation of the Proterozoic Västra Gråshöjden W-Mo bearing granite shows the small granite to consist of several easterly dipping sheets which converge at depth. W and Mo contents range up to 0.5% and 0.27%, respectively. The Mo content increases with depth in the upper two sheets, and correlates with Sn. Bi contents are high in the samples close to the present surface. Cu, Pb,
... [Show full abstract] and Zn correlate with each other and two populations emerge, related to Ca content, those samples with a high Ca content having low Fe, Cu, Pb, and Zn. The granite has a high silica, weakly peraluminous character, not distinguishing it from barren granites. Trace elements provide a good discrimination, the granite having high Fe, Pb, Th, and U contents, and generally lower Ba, Zr, and Ti. The REE pattern is characterstic for this and other W-Mo granites, with a concave to horizontal shape and large negative Eu anomaly, being a good tool for geochemical prospecting.
