Anatolian is a region in Turkey where vast amount of tectonic activity which was followed by magmatism took place during the Cenozoic era. The Anatolian microplate is bound to the north by the Mediterranean Sea, to the east by the Red sea and, to the south by the Aegean Sea. Ophiolites and suture zones seperate different pieces of continental blocks that came together to form the Anatolian microplate (Altunkaynak et al. 2012). Chorowicz (1999) defines Anatolia as a product of the African and Eurasian plate collision which formed mainly from lithospheric magma. A widespread of magmatism accompanied plate tectonism experienced in this region during the Cenozoic era. The late Eocene (37.3 ± 4.6, measure through K-Ar radiometric dating) marks the initial period where this magmatism in took place. This essay will establish if whether an East-west spatial control on the chemistry of Anatolian volcanics exists.
Spatial control is a geographical process in space which didctates how the events of a certain process in space take place. East-west spatial control means that when moving from East-West are there geographical processes in space which are controlling the chemistry of Anatolian volcanics.
The tectonic and magamatic activity that took place in Anatolia makes it a suitable place to study magma evolution as it preserves most of its volcanic rocks. Coban (2007) gave major subdivisions of the Anatolian microplate which are: the Eastern Anatolian collisional province (EACP), the central Anatolian province and, the Western Anatolian extensional province (WAEP) respectively. Two main tectonic processes are responsible for the distribution Anatolian volcanics and the process responsible are: the formation of topography related to the accretion of Anatolian microplate caused by convergence of African-Arabian and Eurasian plates, and the movement of the Anatolian microplate towards west caused by the open of the Aegean basin. This convergence of the Afican and Eurasian plate was followed by the opening up of the Aegean basin. Calc-alkaline magmatic event related to collision in North-western Turkey was replaced by ultrapotassic to potassic magmatic activity which took place in the south-eastern, south-western and western Turkey.
Magmatism in the Western Anatolian province started in the late Cenozoic era as mentioned by Aldanmaz et al. (2000) and the tectonic activity of the western Anatolian province ranges from collision (Early-Middle Miocene) regimes which are followed by extensive regimes (Middle-Late Miocene).The Early-Middle Miocene collision was caused by the convergence of the...
