Geochemistry and REE distribution of apatite from pyroxenite and carbonatite in the Lillebukt Alkaline Complex, Stjernøy, Finnmark, Northern Norway
(NGU-Rapport (2010.004), Report, 2010)This report presents a chemical analysis of apatite from pyroxenite in the Lillebukt alkaline complex together with older analytical data on REE in apatite from the associated carbonatite. Published REE data on apatite ... -
Palaeoproterozoic magnesite-stromatolite-dolomite-"red beds"assocation, Russian Karelia: palaeoenvironmental constraints on the 2.0 Ga positive carbon isotope shift.
(NGU-Rapport (99.052), Report, 1999)Forkortet The ca. 2000 MA Tulomozerskaya Formation, Russian Karelia, representests the most 13C-rich carbonates (up to +18%)which have ever been reported. The implication of this excursion for our understanding of the ... -
Petrography, mineralogy and whole-rock data of the major lithologies of the Fen Complex
(NGU-Rapport (2013.034), Report, 2013)This report documents the petrography of a limited sample set consisting of 12 specimens from the Fen complex, Telemark, South Norway. The samples comprise several, texturally variable calciocarbonatites (søvite), one ... -
Rare earth elements (REE) in two long drill-cores from the Fen Carbonatite Complex, Telemark, Norway (preliminary version)
(NGU-Rapport (2019.008), Report, 2019)Rare Earth Elements (REE) are metals that are classified as critical for the European industry. They are fundamentally important in the manufacturing of HiTech and green technology products. Today almost the total world ... -
