“…4). Larger-volume magmatism is represented by the granitoid intrusions of the Transscandinavian Igneous Belt (TIB) which were emplaced in two major phases c. 1810-1770 and 1720-1660 Ma and which are now largely preserved within the nappes of the Caledonian orogenic belt and in southern Sweden (Romer et al, 1992;Åhäll and Larson, 2000).

Security of supply of a number of raw materials is of concern for the European Union; foremost among these are the rare earth elements (REE), which are used in a range of modern technologies. A number of research projects, including the EURARE and ASTER projects, have been funded in Europe to investigate various steps along the REE supply chain. This paper addresses the initial part of that supply chain, namely the potential geological resources of the REE in Europe. Although the REE are not currently mined in Europe, potential resources are known to be widespread, and many are being explored. The most important European resources are associated with alkaline igneous rocks and carbonatites, although REE deposits are also known from a range of other settings. Within Europe, a number of REE metallogenetic belts can be identified on the basis of age, tectonic setting, lithological association and known REE enrichments. This paper reviews those metallogenetic belts and sets them in their geodynamic context. The most well-known of the REE belts are of Precambrian to Palaeozoic age and occur in Greenland and the Fennoscandian Shield. Of particular importance for their REE potential are the Gardar Province of SW Greenland, the Svecofennian Belt and subsequent Mesoproterozoic rifts in Sweden, and the carbonatites of the Central Iapetus Magmatic Province. However, several zones with significant potential for REE deposits are also identified in central, southern and eastern Europe, including examples in the Bohemian Massif, the Iberian Massif, and the Carpathians.

“…The age of 1,634±3 Ma places the Dalsfjord monzonite in the context of a major orogenic period (Gothian) which built much of the continental crust now exposed in a domain stretching from southern Sweden to the WGR in western Norway (Gaál and Gorbatchev 1987;Tucker et al 1987Tucker et al , 1990Skår et al 1994;Christoffel et al 1999;Åhäll and Larson 2000). In the WGR, a magmatic arc was formed between about 1,690 and 1,630 Ma, presumably outboard of the pre-existing continental crust, and apparently growing progressively towards the south (e.g., Tucker et al 1987Tucker et al , 1990Skår 1998;Austrheim et al 2002).…”

The Dalsfjord Complex is an allochthonous crystalline unit in the hanging wall of a major extensional detachment of the Caledonian orogen on the western coast of Norway. U-Pb geochronology has been carried out to test a previously proposed correlation between this unit and the Jotun Nappe Complex, a member of the Middle Allochthon now occupying a foreland position to the east. A monzonite sample of the Dalsfjord suite yields a zircon age of 1,634±3 Ma, whereas a crosscutting gabbro was formed at 1,464±6 Ma. Both rocks were strongly overprinted during the Sveconorwegian orogeny, especially the monzonite whose zircons U-Pb data were strongly pulled towards a lower intercept age of 882±29 Ma, and whose titanite indicates a two-stage growth history at >960 Ma and <920 Ma. These relationships support the correlation of these units with the Jotun Complex, and to some degree also with the Lindås Nappe in the Bergen Arcs.
