Gözebaşı Köyü (Elazığ Güneyi) Çevresindeki Yüksekova Karmaşığı’na Ait Volkanik Kayaçların Jeokimyasal Özellikleri

Çalışma alanı Güneydoğu Anadolu Orojenik Kuşağı içerisinde, Elazığ İli’nin yaklaşık 30 km güneyindeyer almaktadır. Bu alandaki Üst Kretase yaşlı Yüksekova Karmaşığı volkanik kayaçları, plajiyoklas,klinopiroksen, alkali feldispat, olivin ve manyetit, ilmenit gibi opak oksit mineralleri içermektedir.Kayaçlarda, intergranüler, glomeroporfirik, hyalomikroporfirik ve amigdaloidal dokular yaygındır.Kayaçların petrografik ve jeokimyasal karakteristikleri bazaltik bileşim ve toleyitik karakteriyansıtmaktadır. Kayaç örneklerinin N-MORB’a normalize edilmiş iz element dağılımları baz alındığında;LIL elementler değişkenlik göstermekle birlikte, genel olarak HFS elementlere göre zenginleşmişlerdir.Örneklerin nadir toprak element dağılımları yatay bir desen sergilemektedir. Sonuç olarak; jeokimyasalveriler, Gözebaşı Köyü (Elazığ Güneyi) çevresindeki volkanik kayaçları veren magmanın gelişimindedalan okyanus kabuğu katkısına ve bu kayaçların bir okyanus içi yitimle ilişkili olarak geliştiklerine işaretetmektedir

Geochemical Properties of the Volcanic Rocks of Yüksekova Complex Around Gözebaşı Village (South of Elazığ)

The study area is located in the Southeastern Anatolia Orogenic Belt, approximately 30 km south of Elazig Province. The rocks contain plagioclase, clinopyroxene, alkaline feldspar, olivine and opaque oxide minerals such as magnetite, ilmenite. Intergranular, glomeroporphyritic, hyalomicroporphyritic and amygdaloidal textures are common. Petrographic and geochemical characteristics of the rocks reflect basaltic composition and tholeiitic character. Considering to N-MORB normalized trace element distributions, the rock samples show LIL elements variations, but they show enrichments in large ion lithophile elements (LILE) relative to high field strength elements (HFSE). The rare earth element distributions of the samples exhibit a flat pattern. As a result; all geochemical data point that the contribution of subducted oceanic crust in development of the magma forming volcanic rocks around Gözebaşı village (Elazığ South)
