  • Data are from Nutman & Bridgwater (1986), Nutman et al. (1996, 1999, 2007b), Polat & Hofmann (2003), Jenner (2007) and the Geological Survey of Greenland (previously unpublished data of A. Nutman, and compilations of the late V. R. McGregor and the late D. Bridgwater). Lithology abbreviations in the fourth row are: layered-p, layered peridotite (from layered basic intrusions); anorth, anorthosite (from layered basic intrusions); IAB, metabasaltic amphibolite with chemical affinities with island arc basalt; bon, metabasaltic amphibolite with chemically affinities with boninites; qtz-diorite, quartz diorite; trondhj, trondhjemite. Age constraints in the fifth row are from SHRIMP U/Pb zircon geochronology: >XXXX Ma is where the minimum age for mafic or ultramafic rocks has been obtained from intrusive tonalite sheets; c. XXXX Ma is the likely age based on geological relationships and associated dated rocks. Other ages are direct ages on the samples for which whole-rock analyses are presented. (Analytical methods are described in the source references.)
