...–1.86 Ga Svecofennian juvenile crust between 1.88 and 1.68 Ga. Zircon xenocrysts (1.91–1.98 Ga) with initial ε Hf = +0 to +2.5 from one of the intrusions provide additional evidence for such a long-lived crustal source of granitic magmas in central Fennoscandia. The granitoids were emplaced during...

..., Värmland (Filipstad granite), and Småland, represent the TIB suite of rocks (Transscandinavian Igneous Belt), which formed mainly around 1.8 Ga ago and are essentially undeformed. Two of the southernmost sample areas—the Vånga granite ( Geisler and Schleicher 2000 ) and the Götemar granite ( Söderlund et...

... to the south of Axamo Airport, west of the city of Jönköping (57.74572°N, 14.06378°E). The contacts with the host granite are not exposed, but the strike of the dyke is estimated at NW–SE, roughly parallel to the gneiss fabric in the granite host rocks. The sample is dark grey with a brownish tint...

... parts of the oldest known zircon grain from the Jack Hills metasedimentary belt (Yilgarn Craton, Western Australia). These ages range between 4.4 and 4.3 Ga ( Wilde et al. 2001 ). The oldest rocks known on Earth are 4.03 Ga granitic gneisses of the Acasta Gneiss Complex of the NW Territories of Canada...

... to form mineral deposits can result from magmatic processes, such as in peralkaline silica-undersaturated rocks, peralkaline granites, pegmatites, and in carbonatites (e.g., Chakhmouradian and Zaitsev 2012 , and references therein). Importantly, carbonatite-associated REE mineralizations are in most...

... of sedimentary or volcanic origin and locally grades to coarser granitic textures. The chemical composition, especially the high K 2 O content (5.3–10.5 wt.%), the high abundance of K-feldspar, the occurrence of fluorite, and the euhedral and oscillatory zoned habit of zircon and allanite support a magmatic...
