MARC recordSome Norwegian ophiolite complexes reconsidered / Rolf-Birger Pedersen, Harald Furnes, Greg Dunning.
| Title: | Some Norwegian ophiolite complexes reconsidered / Rolf-Birger Pedersen, Harald Furnes, Greg Dunning. |
| Author(s): | Pedersen, Rolf-Birger. Furnes, Harald. Dunning, Greg. |
| Date: | 1988. |
| In: | Norges Geologiske Undersøkelse. Special Publication. (1988.), Vol. 3 (1988) |
| Abstract: | U/Pb zircon geochronology shows ophiolite complexes formed during at least three spreading events. Two oldest, represented by Karmøy, Gulfjellet and Leka complexes, seem to have occurred in arc-related intra-oceanic basins. Age and rock types suggest that all represent parts of Early Ordovician system. Last phase of spreading-related magmatism occurred in Caradocian time, probably in marginal basin. This was broadly at same time as Taconian emplacement onto Laurentian margin, while obduction of Solund/Stavfjorden ophiolite occurred around Scandian, Silurian-Devonian continent collision. |
