Formation of the Late Palaeozoic Konya Complex and comparable units in southern Turkey by subduction–accretion processes: Implications for the tectonic development of Tethys in the Eastern Mediterranean region

Early Triassic potassic volcanism in the Afyon Zone of the Anatolides/Turkey: implications for the rifting of the Neo-Tethys

“…In this study, we focus on the trachyandesitic metavolcanics of the Afyon Zone in Sızma-Kadınhanı/Konya area, which have been reported previously in many papers (Eren and Kurt 2000;Göncüoglu et al 2007; Robertson and Ustaömer 2009). The aim of this paper is to present the new evidence on the stratigraphical position, detailed primary facies characteristics, and radiometric age data of these potassic volcanics.…”

“…Similarly, based on the preliminary radiometric data, a Lower Permian age has been envisaged for the same volcanics (Akal et al 2007;Candan et al 2009). Recently, in a compilation of the general stratigraphy of the Konya region, the existence of a distinct volcano-sedimentary unit consisting of lava flows, pyroclastics, and epiclastics between Silurian to Lower Carboniferous carbonates, siliciclastics sequence, and Triassic metaclastics has been suggested by Robertson and Ustaömer (2009). Except for the spilitic and gabbroic rocks, which are interpreted as blocks in the siliciclastics unit, all metavolcanics of the region consisting of basalts, andesites, rhyolites, and trachyandesites have been included into this unit.…”

“…Near Simav and Kütahya, western part of the Afyon Zone, they are dominated by rhyolite and dacite (Kaya et al 1995;Akal et al 2005). In the central part of the Zone in the Konya-Sızma area, they consist of trachyandesites, andesites, rhyolites, and basalts (Ö zcan et al 1990;Kurt 1996;Kurt and Arslan 1999;Eren and Kurt 2000;Eren et al 2004;Göncüoglu et al 2003Göncüoglu et al , 2007Akal et al 2007;Robertson and Ustaömer 2009). Based on geochemical data, different tectonic settings such as rift, within-plate, continental arc, and MORB have been suggested for these metavolcanic rocks (Kurt 1996;Eren and Kurt 2000;Eren et al 2004;Akal et al 2005;Göncüoglu et al 2007;Robertson and Ustaömer 2009).…”

Although no radiometric age data are available from these metavolcanics, they are included within the pre-Mesozoic basement of the Afyon Zone and Devonian to Early Permian ages are assigned based on geological relationships (Ö zcan et al 1990;Eren 2001;Göncüoglu et al 2007;Akal et al 2007).…”

Diverse tectonic settings of formation of the metaigneous rocks in the Jurassic metamorphic accretionary complexes (Refahiye, NE Turkey) and their geodynamic implications
