Petrogenetic evolution of the Koziakas ophiolite complex (W. Thessaly, Greece)

Mineralogical, Petrographic and Stable Isotopic Study of Ancient White Marble Quarries in Thessaly, Greece - Ii. Chasanbali, Tempi, Atrax, Tisaion Mountain

“…The basement is structurally overlain by the composite Pelagonian nappe consisting of a basal tectonic mélange, exposed in northern Euvoia and in Koziakas (Danelian and Robertson, 2001;Pomonis et al, 2007), including Triassic metavolcanic series (metarhyolites, amphibolites, mica-schists, greenschists) and Triassic-Jurassic deep-water metasedimentary rocks (mainly schists, prasinites, amphibolites, marbles and dolomitic marbles).…”

Petrogenetic Implications for Ophiolite Ultramafic Bodies from Lokris and Beotia (Central Greece) Based on Chemistry of Their Cr-spinels

“…The mantle section of many ophiolites contains clearly compositionally heterogeneous peridotites, e.g., [60][61][62], which display mineralogical, textural and compositional evidence for complex, multi-phase melting, depletion and enrichment processes in their petrogenetic history [63,64]. Moreover, the studied Cr-spinels hosted in the harzburgite and dunite resemble those occurring in ultramafic rocks from Pindos and Othris ophiolites, while the Cr-spinels from Alyki resemble those occurring in lherzolites from Iti, Kallidromon, Othris and Koziakas ophiolites that have been interpreted as being formed (entirely or partially) in SSZ settings [32][33][34][35][36][37][38][39]44,65], thus pointing to a similar origin.

“…Fields for mid-ocean ridge basalts (MORB) and island arc volcanics (IAV), as well as MOR and supra-subduction zone (SSZ) peridotites according to [7]. Field for spinels from Iti, Othris and Koziakas peridotites are according to [35][36][37][38][39]. Legend as in Figure 5a.…”

Petrological, Mineralogical and Geochemical Data From the Eohellenic Ophiolitic Nappe in the Island of Skyros, Greece

“…For example, the ophiolitic sequences of Pindos, Koziakas and West Othris present mostly MORB and back-arc basin (BAB) affinities (e.g. Pomonis et al, 2007;Pelletier et al, 2008;Whattam and Stern, 2011), whereas the ophiolitic sequences of East Othris, Vourinos, Rhodiani and Evros are supra-subduction zone (SSZ) ophiolites (Beccaluva et al, 1984;Magganas, 2002;Saccani et al, 2008;Magganas and Koutsovitis, 2015). The Skyros ophiolitic rocks, occurring within the eastern zone and along with schists, phyllites and marbles, are part of the Eohellenic tectonic nappe (Harder et al, 1983).…”
