Melt-mineral-fluid interaction in peralkaline silicic intrusions in the Oslo Rift, Southeast Norway. I. Distribution of elements in the Eikeren ekerite.
Neumann, E.R.; Andersen, T.; Hansteen, T.H. (NGU Bulletin (417), Journal article, 1990)The behaviour of different elements during formation of the Eikeren ekerite (alkali granite) has been studied with the help of an element correlation matrix. The compositional relations are the result of partitioning of ... -
Melt-mineral-fluid interaction in peralkaline silicic intrusions in the Oslo Rift, Southeast Norway. III. Alkali geothermometry based on bulk fluid inclusion content.
Andersen, T.; Hansteen, T.H. (NGU Bulletin (417), Journal article, 1990)Decrepitation-linked ICP analyses of bulk fluid inclusion in quartz in 14 samples from the Sande nordmarkite (quartz syenite) and the Eikeren Skrim ekerite (alkali granite) plutonic complexes yield Na\/K ratios which suggest ... -
Porphyritic syenite at Lake Mykle, the Oslo Rift - a possible derivative of larvikite.
Andersen, T.; Westphal, N. L.; Frei, R. (NGU Bulletin (442), Journal article, 2004)New Rb-Sr and Sm-Nd isotope data on porphyritic syenite from lake Mykle in the southern part of the Oslo Rift confirm a close compositional and genetic relationship and genetic relationship between this rock and the ...
