Geology, geochemistry and geodynamic implications of the mafic–ultramafic rocks from the northern part of the Antalya Complex, SW Turkey

Engineering Properties of Eğirdir-Kızıldağ Harzburgitic Peridotites in Southwestern Turkey

“…The study [29] was focused on the maficultramafic rocks on the north wing of the Antalya complex in Southwest Turkey in terms of geological, chemical and geodynamic properties (Fig. 1).…”

“…2). These harzburgites contain magmatic foliation and there are pyroxene minerals or pyroxene-rich thin layers parallel to this banding [29]. The mineralogical composition of these rocks, and the scarcity or abundance of the minerals, is very important in terms of naming the rocks, the cutting and polishing of the rocks, trade value and even block production.…”

Petrology of the late Triassic mafic volcanic rocks from the Antalya Complex, southern Turkey: evidence for mantle source characteristics during the Neotethyan rifting

“…These patterns display light rare earth element (LREE) enrichment and heavy rare earth element (HREE) fractionation (La N / Yb N = 15.14-19.77), indicating the asthenosphere as a possible origin for enriched mantle source components, exhibiting highly close similarity with the ocean island basaltic units (Sun and McDonough, 1989) (Figure 7a). The alkaline basalts of the Koçali (La N /Yb N = 7.0-21.5), Antalya (La N /Yb N = 9.3-18.3), and Mamonia (La N /Yb N = 4.2-15.2) Complexes are characterized by a similar LREE enrichment (Lapierre et al, 2007;Varol et al, 2007Varol et al, , 2011Maury et al, 2008;Elitok, 2012;Robertson et al, 2016) (Figures 7c, 7e, and 7g). In contrast, Late Triassic tholeiitic volcanics in Antalya (La N /Yb N = 1.1-2.3), Koçali (La N /Yb N = 1.0-2.0), and Mamonia (La N /Yb N = 0.6-1.6) Complexes exhibit LREE-depleted to flat REE patterns and are more akin to E-MORB (Figures 7c, 7e, and 7g).…”

“…Published data for basic volcanic rocks from the Antalya (Varol et al, 2007;Maury et al, 2008;Elitok, 2012), Mamonia (Cyprus) (Lapierre et al, 2007), and Koçali (Adıyaman) (Varol et al, 2011;Robertson et al, 2016) Complexes will be used together with our results to compare and better understand the magma source characteristics during Southern Neotethyan rifting. Based on the Zr/Ti vs. Nb/Y ratios, volcanic rocks from the Saklıkent (Antalya) region are represented by alkaline basalts (Nb/Y = 1.54-2.82) in Figure 6 (after Pearce, 1996), in accordance with the Triassic alkaline basalts of the Antalya Complex (Varol et al, 2007;Maury et al, 2008;Elitok, 2012), ocean island basalts (OIB) of the Koçali (Varol et al, 2011;Robertson et al, 2016), and Type-3 alkali basalts of the Mamonia Complex (Lapierre et al, 2007). In contrast, the subalkaline basaltic rocks defined as enriched midocean ridge basalts (E-MORB) from the Koçali Complex (Varol et al, 2011;Robertson et al, 2016), as well as Type 1-2 volcanics from Mamonia (Lapierre et al, 2007) and Antalya (Elitok, 2012) were characterized by lower Nb/Y contents ( Figure 6).…”

“…Studies performed on the Antalya Complex (Robertson and Waldron, 1990;Varol et al, 2007;Maury et al, 2008;Elitok, 2012), the Mersin ophiolitic mélange (Parlak and Robertson, 2004;Tekin et al, 2019), the Bitlis Massif (Perinçek, 1980), the Koçali Complex (Varol et al, 2011;Robertson et al, 2016) in Turkey, the Mamonia Complex in southwestern Cyprus (Lapierre et al, 2007), the Baer-Bassist ophiolites in northern Syria (Delaune-Mayère, 1984;Al-Riyami et al, 2002), the Avdella mélange in Greece (Jones and Robertson, 1991), the Hawasina basin in Oman (Lapierre et al, 2004), the central and southern Greece (Pe-Piper, 1982), Albania (Shallo et al, 1990), and the Dinarides in Serbia (Robertson and Karamata, 1994) documented Permo-Triassic volcanisms associated with the rifting of the Neotethyan oceanic basins.…”
