Potentials of rare earth element and Zr-, Be-, U-, Th-, (W-)mineralisations in central and northern Nordland
The Geological Survey of Norway (NGU) was contacted by Nordland Mineral (T. Vrålstad) in May 2010 to evaluate the potential of economic rare-earth-element (REE: Ce-Lu, Y) and Zr-mineralisations and related Be-, U-, Th-, (W-) mineralisations in Proterozoic basement windows and overlying Caledonian na...

The Geological Survey of Norway (NGU) was contacted by Nordland Mineral (T. Vrålstad) in May 2010 to evaluate the potential of economic rare-earth-element (REE: Ce-Lu, Y) and Zr-mineralisations and related Be-, U-, Th-, (W-) mineralisations in Proterozoic basement windows and overlying Caledonian nappe complexes in central and northern Nordland between Mo i Rana in the south and Ofotfjorden in the north. The economic background for the study is the increasing demand for several of these elements.
