“…Late Cretaceous syenites with associated carbonatites and fluorite mineralisation have been described from east-central Anatolia, including the Karaçayir pluton (Cooper et al, 2011) and the area around Malatya, which contains the Sofular carbonatite (Ozgenc, 1999;Ozgenc and Ilbeyli, 2009). The Quaternary alkaline volcanism of Gölcűk, close to Isparta in south-western Turkey, shows enrichment in the REE (Platevoet et al, 2014) and has been proposed as a possible source for heavy minerals in the nearby Çanakli placer (Aksu Diamas REE prospect). This prospect has an inferred resource estimate of 494 Mt.…”

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.

“…A mantle component with a high 206 Pb/ 204 Pb signature was previously suggested to explain the origin of some strongly potassic rock suites in western Anatolia; however, based on its unradiogenic 87 Sr/ 86 Sr signature (which is referred to as an “intraplate” signature), this component has since been interpreted to reflect an asthenospheric origin with the possible contribution of carbonatitic fluids (Caran, ; Elitok et al, ; Platevoet et al, ; Prelević et al, ). However, no effort has yet been made to explain the highly radiogenic 206 Pb/ 204 Pb signature of this component, which appears to require long‐term isolation from the mantle convection.…”

“…To show the effect of sediment melt addition the modelling was performed using two different sediment compositions (samples AMS-007 and AMS-024 from the dataset of Klaver et al, 2015), and the depleted ( (Aldanmaz et al, 2000;Ersoy and Palmer., 2013;Prelević et al, 2012).

However, no effort has yet been made to explain the highly radiogenic 206 The lavas that record the clear influence of this component appear to be confined to a period of activity following the Late Miocene; their areal distribution is limited within a belt in the southwestern part of Anatolia (Figure 1), where the interaction of variably depleted mantle peridotites with fluids or melts from recycled carbonate-rich sediments has been suggested to play a role in modifying the composition of the lithospheric mantle to produce phlogopitebearing mantle components.…”

“…However, regardless of the type of material involved and the processes envisioned, it has been suggested that subduction‐related metasomatic components share some common isotopic signatures (usually defined as “orogenic” signatures), which are represented by high 87 Sr/ 86 Sr and low 143 Nd/ 144 Nd values (Aldanmaz et al, ; Çoban et al, ; Ersoy & Palmer, ; Prelević et al, , ). On the other hand, melt compositions with distinctly low 87 Sr/ 86 Sr (<0.7040), high 143 Nd/ 144 Nd (>0.5128), and radiogenic 206 Pb/ 204 Pb values (defined as “anorogenic” signatures) have been interpreted to primarily reflect the involvement of melts from the convecting asthenospheric mantle (Dilek & Altunkaynak, ; Elitok et al, ; Ersoy & Palmer, ; Platevoet et al, ; Prelević et al, , ).…”

Some remarks on the nature of mantle metasomatism beneath western Anatolian–Aegean region: Contrasting isotopic signatures recorded in the Miocene lavas from the Söke Basin

2018

The presence of a subduction signature with variable isotopic patterns in the melt products of mantle origin within the Aegean–Anatolian domain reflects the differential effects of slab‐derived material on the chemical composition of the supraslab mantle region. Here, we use Sr–Nd–Pb isotopic compositions and major and trace element abundances to evaluate the characteristics of the source components and possible roles of fluid/melt metasomatism in the genesis of the Middle to Late Miocene mafic–intermediate lavas from the Söke Basin in western Anatolia. This volcanic suite comprises a number of individual lava flows in which the dominant rock types are potassium‐rich basaltic andesites and andesites with trace element relative abundances indicative of melt derivation from subduction‐modified sources. These samples have significantly heterogeneous Sr and Nd isotopic ratios, with 87Sr/86Sr and 143Nd/144Nd values ranging from 0.70475 to 0.70927 and from 0.51218 to 0.51270, respectively; they also yield a range of Pb isotope ratios, with 206Pb/204Pb = 18.963–19.344, 207Pb/204Pb = 15.672–15.733, and 208Pb/204Pb = 39.096–39.264. Remarkably large variations in isotopic ratios with relatively limited changes in major elements suggest the involvement of heterogeneously enriched sources with diverse isotopic signatures. The modelling of trace element and isotopic data indicates that parts of the lithospheric mantle in this region are isotopically enriched, with geochemical signatures that reflect the interaction of variably depleted mantle peridotites with melts from subducted sediments of continental crustal origin, while other parts host phlogopite‐rich metasomatic components with signatures of devolatilization reactions from ancient subduction events that led to the preferential loss of Pb and Rb to create metasomatic domains with high U/Pb and low Rb/Sr values that ultimately generated highly radiogenic 206Pb/204Pb and relatively unradiogenic 87Sr/86Sr values. The observed isotopic diversity in relatively short‐time‐ and length‐scales may be interpreted to have resulted largely from the variable extent of melt contributions from a number of discrete lithological domains with contrasting long‐term isotopic evolution and is consistent with the view that the continental lithosphere in this region comprises a number of disparate lithospheric fragments with different petrogenetic histories.
