U–Pb dating of detrital zircons for sediment provenance studies—a comparison of laser ablation ICPMS and SIMS techniques
TL;DR: In this article, a real-time mass bias correction is made by aspirating a Tl/U tracer at the same time as laser ablation, which is similar to that described in Horn et al. (2000), except that enriched 233U rather than 235U is used in the tracer solution Correction for laser-induced Pb/U elemental fractionation is based on a mathematical treatment of time-resolved data that is independent of laser-ablation characteristics.
Book ChapterDOI
The Use of Mantle Normalization and Metal Ratios in Discriminating between the Effects of Partial Melting, Crystal Fractionation and Sulphide Segregation on Platinum-Group Elements, Gold, Nickel and Copper: Examples from Norway
Sarah-Jane Barnes,Rognvald Boyd,A. Korneliussen,L.P. Nilsson,Morten Often,Rolf-Birger Pedersen,B. Robins +6 more
TL;DR: In this paper, the relative importance of the influence of sulphides, chromite, olivine and PGM on the distribution of noble metals, Ni and Cu in mafic and ultramafic rocks is examined.
Journal ArticleDOI
The Sveconorwegian Pegmatite Province – Thousands of Pegmatites Without Parental Granites
TL;DR: In this paper, the Niobium-Yttrium-fluorine (NYF) signature of Sveconorwegian pegmatites is used to classify them.
Journal ArticleDOI
The Solund-Stavfjord ophiolite complex and associated rocks, West Norwegian Caledonides; geology, geochemistry and tectonic environment
Harald Furnes,Kjell Petter Skjerlie,Rolf-Birger Pedersen,Torgeir B. Andersen,C. J. Stillman,R. J. Suthren,M. Tysseland,L. B. Garmann +7 more
TL;DR: In this paper, the authors show that the upper Ordovician Solund-Stavfjord Ophiolite Complex of the westernmost Norwegian Caledonides shows N-to E-MORB affinity, with high Th/Ta (or Nb) ratios giving evidence of subduction influence.
Journal ArticleDOI
A U/Pb age for the Sulitjelma Gabbro, North Norway: further evidence for the development of a Caledonian marginal basin in Ashgill–Llandovery time
TL;DR: The Sulitjelma Gabbro in the central Norwegian Caledonides has been dated with the U/Pb zircon/sphene method to 437±2 Ma as mentioned in this paper.
