Summary
In this report results of the investigation of potential rare earth elements (REE) and Zr-, Be, U-, Th-, (W-) mineralisations in central and northern Nordland are presented. The investigated and sampled mineralisations were proposed in NGU report 2009.037 on the basis if existing reports and geochemical data sets. The investigation targets were evolved Proterozoic TIB-type granites (TIB = Trans-Scandinavian Igneous Belt) of the Tysfjord, Sommerset and Rishaugfjell basement windows, in particular, the Hatten- Tilthornet massif, Hundholmen, Kjerrfjellet, Hellemobotn, Reinoksskardet, upper Gjerdalen areas, the Sommerset basement Window, Rismålsvatn, and Memaurvatn. The general aim was to identify Zr-Ree mineralisations with >= 2wt.% REO (including Y2O3; REO - rare earth oxides) which are possibly enriched in Be, U and Th as well.
