Abstract. We investigate the occurrence and chemistry of magmatic sulfides and their chalcophile metal cargo behaviour during the evolution of compositionally different magmas from diverse geodynamic settings both in mineralised and barren systems. The investigated areas are the following: (a) the Miocene Konya magmatic province (hosting the Doğanbey Cu–Mo porphyry and Inlice Au epithermal deposits, representing post-subduction) and (b) the Miocene Usak basin (Elmadag, Itecektepe, and Beydagi volcanoes, the latter associated with the Kişladağ Au porphyry in western Turkey, representing post-subduction). For comparison we also investigate (c) the barren intraplate Plio-Quaternary Kula volcanic field west of Usak. Finally, we discuss and compare all the above areas with the already studied (d) Quaternary Ecuadorian volcanic arc (host to the Miocene Llurimagua Cu–Mo and Cascabel Cu–Au porphyry deposits, representing subduction). The volcanism of the newly studied areas ranges from basalts to andesites–dacites and from high-K calc-alkaline to shoshonitic series. Multiphase magmatic sulfides occur in different amounts in rocks of all investigated areas, and, based on textural and compositional differences, they can be classified into different types according to their crystallisation at different stages of magma evolution (early versus late saturation). Our results suggest that independently of the magma composition, geodynamic setting, and association with an ore deposit, sulfide saturation occurred in all investigated magmatic systems. Those systems present similar initial metal contents of the magmas. However, not all studied areas present all sulfide types, and the sulfide composition depends on the nature of the host mineral. A decrease in the sulfide Ni∕Cu (a proxy for the monosulfide solid solution (mss) to intermediate solid solution (iss) ratio) is noted with magmatic evolution. At an early stage, Ni-richer, Cu-poorer sulfides are hosted by early crystallising minerals, e.g. olivine–pyroxene, whereas, at a later stage, Cu-rich sulfides are hosted by magnetite. The most common sulfide type in the early saturation stage is composed of a Cu-poor, Ni-rich (pyrrhotite mss) phase and one to two Cu-rich (cubanite, chalcopyrite iss) phases, making up ∼84 and ∼16 area % of the sulfide, respectively. Sulfides resulting from the late stage, consisting of Cu-rich phases (chalcopyrite, bornite, digenite iss), are hosted exclusively by magnetite and are found only in evolved rocks (andesites and dacites) of magmatic provinces associated with porphyry Cu (Konya and Ecuador) and porphyry Au (Beydagi) deposits.

Abstract. We investigate in both mineralised and barren systems the occurrence and chemistry of magmatic sulphides and their chalcophile metal cargo behaviour during evolution of compositionally different magmas in diverse geodynamic settings. The investigated areas are: (a) the Miocene Konya magmatic province (hosting the Doganbey Cu-Mo and Inlice Au-epithermal deposits) (Post-Subduction) and (b) the Miocene Usak basin (Elmadag, Itecektepe and Beydagi volcanoes, the latter associated with the Kisladag Au porphyry) in Western Turkey (Post-Subduction). For comparison we also investigate (c) the barren Plio-Quaternary Kula volcanic field, west of Usak (Intraplate) and finally we discuss and compare all the above areas with the already studied (d) Quaternary Ecuadorian volcanic arc (host to the Miocene Llurimagua Cu-Mo and Cascabel Cu-Au porphyry deposits) (Subduction). The volcanism of the studied areas displays a wide range of SiO2 spanning from basalts to andesites/dacites and from high K-calc-alkaline to shoshonitic series. Multiphase magmatic sulphides occur in different amounts in all investigated areas and based on textural and compositional differences, they can be classified in different types, which crystallised at different times (early versus late saturation). A decrease in the sulphide Ni/Cu (proxy for mss-monosulphide solid solution/iss-intermediate solid solution) ratio is noted with magmatic evolution. Starting with an early stage, saturating Ni-richer/Cu-poorer sulphides hosted by early crystallising minerals e.g. olivine/pyroxene, leading up to a later stage, producing Cu-richer sulphides hosted by magnetite. The most common sulphide type resulting from an early saturating stage is composed of a Cu-poor/Ni-rich (pyrrhotite/mss) and one/two Cu-rich (cubanite, chalcopyrite/iss) phases making up 84 and 16 area % of the sulphide, respectively. Our results suggest that independently of the magma composition, geodynamic setting and whether or not the system has generated an ore deposit on the surface, sulphide saturation occurred in variable degrees in all studied areas and magmatic systems and is characterised by a similar initial metal content of the magmas. However not all studied areas present all sulphide types and the sulphide composition is dependent on the nature of the host mineral. In particular sulphides, resulting from the late stage, consisting of Cu-rich phases (chalcopyrite ,bornite, digenite/iss) are hosted exclusively by magnetite and are found only in magmatic provinces associated with porphyry Cu (Konya and Ecuador) and porphyry Au (Beydagi) deposits.

<p>The study of magmatic enclaves can provide a vertical understanding of the variable levels at which magmatic differentiation occurs, allowing us to quantify the conditions under which processes like sulfide saturation take place. Recent studies have confirmed the importance of lower crustal hornblende-rich enclaves (Chang and Audétat, 2018) and deep pyroxene-rich cumulates, as fertile sources in post-subduction and collisional settings, by sequestrating most of the Cu extracted from the mantle (Chen et al., 2019). Moreover, studies of sulfides in the host rock (Keith et al., 2017, Georgatou et al., 2018, 2020) and in enclaves (Du et al., 2014; Georgatou et al., 2018) have shown that sulfide saturation appears to be a multi-stage process starting with Fe,Ni-rich sulfides, switching to Ni-poor, Cu-rich sulfides and finally to only Cu-rich sulfides. Bracketing the P-T range in which sulfide saturation occurs relative to the sulfide occurrence and composition for diverse geodynamic settings in both mineralised and barren systems would permit us to assess the effect of sulfide saturation on the mineralization potential of the ascending residual melt.</p><p>Here, we investigate sulfide-bearing magmatic enclaves from: (i) the Miocene volcano-plutonic complexes of Konya (hosting the Doganbey Cu-Mo-W porphyry and Inlice Au-epithermal) and Usak (hosting the Kisladag giant Au-porphyry), in Western Turkey (post-subduction settings), (ii) the Kula Plio-Quaternary volcano, in the Usak basin, also in Turkey (intraplate OIB-like signature volcano in post-subduction setting). We compare results from the above areas with those of previously studied enclaves (Georgatou et al., 2018) and of new enclaves of the Quaternary Ecuadorian volcanic arc, hosting, among others, the Cascabel Cu-Au Miocene porphyry deposits (subduction setting).</p><p>Our results confirm previous conclusions (Georgatou et al., 2018) that mafic enclaves and cumulates carry a greater amount of sulfides compared to the more felsic host rock and that sulfides are generally Cu-poorer compared to the ones found in the host rock. Preliminary thermobarometry data on sulfide bearing amphibole cores found in the host rock yield P(GPa)/T(<sup>o</sup>C) (Ridolfi et al., 2010) of 0.39-0.53/1060-1093 for Kula, 0.46-0.11/1015-819 for Konya, 0.20-0.33/917-969 for Usak and 0.2-0.38/902-987 for Ecuador. Estimates on amphibole occuring in hornblende-rich enclaves of Kula and Ecuador indicate P/T values of 0.22-0.57/988-1097 and 0.24-0.4/900-1013, respectively. Crossrefencing with Mutch et al., 2016 shows similar temperatures but significantly higher pressures, indicating for the case of Kula 0.69-0.83 GPa in the host rock and 0.53-0.86 GPa in the enclaves. These data suggest widespread sulfide saturation occurring at mid- to upper crustal depths with the highest P-T values corresponding to the onset of early Fe,Ni-rich sulfide saturation. Future investigation of sulfide-rich enclaves found in other areas and crossreferencing with multiple thermobarometers will further constrain the P-T conditions for later stages of sulfide saturation.</p><p> </p><p><em>Chang and Audétat 2018, J.Petrol. 59(10):1869-1898</em></p><p><em>Chen et al., 2019, Earth Planet.Sci.Lett. 531, 115971</em></p><p><em>Du et al., 2014, Geosci.Front. 5,237-248</em></p><p><em>Georgatou et al., 2019, Lithos 296-299,580-599</em></p><p><em>Georgatou and Chiaradia, 2020, Solid Earth 11(1):1-21</em></p><p><em>Keith et al., 2017, Chem.Geol. 451:67–77</em></p><p><em>Ridolfi et al., 2010, Contrib.Mineral.Petrol. 160,45-66</em></p><p><em>Mutch et al., 2016, Contrib.Mineral.Petrol. 171,85</em></p>
