Petrogenesis of the Anorthosite Dyke Swarm of Tromso, North Norway: Experimental Evidence for Hydrous Anatexis of an Alkaline Mafic Complex
The 456 ± 4 Ma Skattøra migmatite complex in the north Norwegian Caledonides consists of migmatitic nepheline-normative metagabbros and amphibolites that are net-veined by numerous nepheline-normative anorthositic and leucodioritic dykes.
