Epithermal gold mineralisation in the active Aegean Volcanic Arc: the Profitis Ilias deposit, Milos Island, Greece

Epithermal Manganese Mineralization, Kimolos Island, South Aegean Volcanic Arc, Greece

“…Milos is host to a large inventory of volcanic-hosted metallic deposits (e.g. Hauck, 1984;Plimer, 2000;Liakopoulos et al, 2001;Kilias et al, 2001;Naden et al, 2005;Alfieris and Voudouris, 2007;Glasby et al, 2005) as well as industrial mineral deposits (Christidis, 2001, and references therein). Recent research on Milos has identified a new metallogenic environment-namely hybrid volcanic-hosted massive sulfide and continental magmato-hy- Francalanci et al, 2007). drothermal mineralization (i.e.…”

Isotope Geochemistry of the Pb-Zn-Ba(-Ag-Au) Mineralization at Triades-Galana, Milos Island, Greece

“…During more recent exploration on the island, the epithermal precious metal deposits of Profitis Ilias and Chondro Vouno, with reported combined resources of 0.8 Moz Au and 12.4 Moz Ag, have been discovered (e.g. Kilias et al, 2001). They were initially classified as low sulfidation-type deposits (Naden et al, 2005).…”

Mineralogy and Geochemistry of the Triadesgalana Pb-Zn-Ag-Au Intermediate-High Sulfidation Epithermal Mineralization, Milos Island, Greece

“…Precious metal-rich mineralization in western Milos Island was formed during the Upper Pliocene to Lower Pleistocene during the emplacement of three successive magma pulses (submarine to subaerial rhyodacite, andesite-dacite) in an emergent volcanic edifice (Alfieris et al, 2013;Kilias et al, 2001;Marchik et al, 2010;Naden et al, 2005). Mineralogical data indicate common features among the Profitis Ilias-Chondro Vouno, Kondaros-Katsimoutis-Vani and Triades-Galana mineralizations, all of them characterized by intermediate-sulfidation epithermal ore assemblages (e.g.…”

“…Metallic mineralization on Milos was the subject of several mineralogical and geochemical studies, with base-and precious metal mineralization in western Milos Island having been classified as either Kuroko- (Hauck, 1988;Vavelidis and Melfos, 1998), seawater-dominated epithermal (Kilias et al, 2001;Liakopoulos et al, 2001;Marchik et al, 2010), shallow submarine epithermal- (Alfieris, 2006;Stewart and McPhie, 2006;Alfieris et al, 2013), or hybrid volcanogenic massive sulfide (VMS)-epithermal types (Naden et al, 2005). A modern analogue for the setting of epithermal -style mineralization in western Milos is the shallow submarine Kolumbo hydrothermal vent field located 7 km NE of Santorini Island in the Hellenic arc (Kilias et al, 2013).…”
