“…Based on K-Ar radiometric age of 11.2 Ma reported by Borsi et al (1972), the Ovacık basalt in this region has been accepted to be Late Miocene in age. Recently, Karacık et al (2013) reported 20.00 ± 1.10 Ma K-Ar radiometric age from this unit. Radiometric ages from the volcanic rocks interbedded with sedimentary units in the Karaburun Peninsula are 21.3-16.0 Ma in age, indicating that the sedimentary succession in the area should be considered Early-Middle Miocene in age.…”

“…The andesitic to rhyolitic rocks of 21.3-16.0 Ma (K-Ar and Ar/Ar ages) in the Karaburun Peninsula (Table 2) are interbedded with the sedimentary succession that begins with Bozköy Formation and grades into the Urla limestone (Helvacı et al, 2009). All these volcanic and sedimentary units are overlain by Urla volcanics which were reported as 13.2-11.9 Ma (Borsi et al, 1972;Karacık et al, 2013). Based on K-Ar radiometric age of 11.2 Ma reported by Borsi et al (1972), the Ovacık basalt in this region has been accepted to be Late Miocene in age.…”

The volcaniclastics, derived from calcalkaline acidic-intermediate volcanism in the region during late Early Miocene, and lacustrine deposits of Middle Miocene and alkaline volcanics are exposed on Uzun Island, Hekim Island, Çiçek Island and Karantina Island in the Outer Gulf of Izmir. Kocadağ volcaniclastics derived from Kocadağ volcanism, by extruding mainly calcalkaline andesitic-dacitic products during Late Early Miocene, represents the exposed oldest rock unit. The volcaniclastic succession extending in the north of Uzun Island is composed of pyroclastics in ignimbrite and blocky ash flow facieses, and epiclastics in volcanic mass flow (lahar) facies. Foça tuff, represented by rhyolitic ignimbrites, originated from an area around Foça and moving to an area around Uzun Island, emplaced onto the Kocadağ volcaniclastics in two main explosive stages. The Değirmentepe Member alluvial deposits composed of coarse volcanic detritus were deposited during a inactive period between the explosion stages. A K/Ar age of 16.0 Ma was obtained from a rhyolite dome, which shows lateral relationship with the correlant ignimbrites in Foça Peninsula, and so it is considered that Foça tuff emplaced onto the region at the end of late Early Miocene. Lacustrine-dominated Middle Miocene succession, which overlies the Foça tuff unconformably, differentiated as the Urla group. Urla group consists of alluvial Beşiktepe Formation, the Pirnalli Island volcaniclastics, which is composed of sublacustrine volcanic density-flow deposits and felsic ignimbrites, Hekim Island basalt comprising basic volcanics and lacustrine Urla limestone, respectively from bottom to top. Beşiktepe formation only exposed on Uzun Island, overlies the Foça tuff with an unconformity indicating a basin margin deposition during the Middle Miocene. Pirnalli Island volcaniclastic succession, which its lower boundary does not expose within the area on Hekim Island and Çiçek Islands, is mainly composed of epiclastics deposited by the dynamics of sublacustrine gravity flow and includes trachytic ignimbrite layers in various welding degrees. The main lithologic components of Pirnalli Island volcaniclastics derived from alkaline trachytic volcanism, which was active during the Middle Miocene in Menteş Peninsula. The eruption center of Hekim Island basalt intruding as a sill to the bottom of Urla limestone succession is on Hekim Island. Along the upper contact of the basalt intruding backshore deposits at the bottom of Urla limestone, the peperites occurred reflecting the interaction between molten lava and unconsolidated sediment. A K/Ar age of 14,8±0,8 Ma is obtained from the basic lavas called as trachybasalt and basaltic trachyandesite according to the major element composition. Hekim Island basalt, which exposed at the center of Foça Depression, can be correlated with both the Ilipinar basalt in Foça Peninsula and the Ovacik basalt in Urla basin with respect to chrono-and lithostratigraphy. Urla limestone succession, which transgressively overlies Hekim Island basalt, b...

“…Despite the variable petrological processes related with the magmatism, post-collisional areas also display stratigraphic sequences which documents the building stages of complex volcanic edifices (Western Anatolia: Yılmaz et al, 2000;Dönmez et al, 2004;Karacık, 2006;Karacık et al, 2013;Ersoy et al, 2014; Eastern Anatolia: Keskin et al, 1998;Özdemir et al, 2006;Oyan et al, 2016;Tibet: Chung et al, 2005;Sulu Belt: Fan et al, 2001;NW Iran: Jahangiri, 2007). Furthermore, understanding the development of the style and facies of the post collisional volcanism and coeval intrusive units can give valuable information about the stages of development of the continental crust and evolution of post-subduction tectonic setting.…”

Abstract:The obliteration of the Neo-Tethyan Ocean along the northern part of Turkey leads the development of the İzmir-Ankara-Erzincan suture zone (IAESZ). After the suturing stage; extension and magmatism concomitantly developed on the both sides and along the IAESZ during the middle Eocene. During this stage, the areas confining to Almus, Yıldızeli, and Yıldızdağ regions have experienced a severe magmatic activity. Middle Eocene magmatism in Almus and Yıldızeli areas are represented by the volcano-sedimentary successions. Besides, in Yıldızdağ region, gabbroic and dioritic intrusives are the dominant manifestations of magmatism. The volcano-sedimentary successions from Almus and Yıldızeli areas represented by shallow marine sedimentary units at the lower parts and lava flows and volcanoclastic units at the middle to upper parts. Eight volcano-sedimentary sections from Almus and Yıldızeli measured to demonstrate the evolution of the magmatic units developed coevally along the both sides of the suture zone. In both regions; three different volcanic episodes are differentiated based on stratigraphy. First episode includes amphibole-basaltic andesite, andesite, and dacite. Second episode contains basalt and pyroxene-basaltic andesite lavas and third episode represented by trachyte and trachyandesite dikes and stocks. The field data from the all regions demonstrated that middle Eocene magmatic units along the post-collision zone concominantly developed in a wide area and triggering of the magmatism controlled by the region-scale delamination and/or lithospheric removal processes.
