geusb-4927	Kokfelt, Thomas F; Næraa, Tomas; Thrane, Kristine; Bagas, Leon	New zircon U-Pb and Hf isotopic constraints on the crustal evolution of the Skjoldungen region, South-East Greenland	2016	4	.pdf	application/pdf	2983	127	55	Both terranes include U-Pb zircon ages between 3100 and 2700 Ma, but the southern terrane also contains a noticeable component of inherited grains between c. 3880 and 3200 Ma (Figs 2, 3). The rare, detected oldest age com- ponents are restricted to the southern part of the region, whereas the dominant ≤3100 Ma age components are equally distributed. 2014) resulted in extensive crustal remelting and continued emplacement of mildly alkaline plutons forming the Skjold- ungen Alkaline Province, which constitutes a globally rare occurrence of Archaean alkaline magmatism (Blichert-Toft et al. 1996).	cache/geusb-4927.pdf	txt/geusb-4927.txt
