Geochemistry And Genetic Interpretation of the Çelebi Instrusion İn The Inner Anatolian Granitoid Belt

Year 1986, Volume: 10 Issue: 4, 27 - 35, 15.10.1986

Abstract

The Inner Anatolian granitoid belt is situated at the western proximity of the Kırşehir Massif. Forty samples of Çelebi granitoid, which contitutes one of the intrusions in the belt, were analysed for major and trace elements. The geochemical properties and the origin of the intrusion are discussed. Principal dark colored minerals of the granitoids in dhe area studied., which have granitic, granodioritic, quartzmonzonitic, quartzmonzodioritic composition and calc-alkaline character, consist of homblend + biotite ± clinopyroxene and titanite. These instrusions contain abundant residual rock inclusions of similar mineralogic composition, and are of I-type granitoid character. They have a high concentration of K, Rb, Sr, Ba, Zr, Nb, Th, U, Rb/Sr, and a low concentration of K/Rb and Sr/Ba. It can be claimed that the Çelebi granitoid, which shows similarities to volcanic arc and post-collision granitoids in terms of the content of certain trace elements, is formed through partial melting of the continental crust ± mantel material, basing on its mineralogical-petrographical and geochemical properties.

İç Anadolu Granitoyid Kuşağındaki Çelebi Sokulumunun Jeokimyası ve Kökensel Yorumu

Abstract

İç Anadolu granitoyid kuşağı, Kırşehir Masifi'nin batı kenarında yer almaktadır. Kuşaktaki sokulumlardan birini oluşturan Çelebi granitoyidine ait 40 örneğin ana ve iz element kimyasal analizleri yapılarak jeokimyasal özellikleri ve kökeni belirlenmeye çalışılmıştır. Granit, granodiyorit, kuvars monzonit, kuvars monzodiyorit bileşiminde ve kalkalkali karakterindeki inceleme alanı granitoyidlerinin önemli koyu renkli minerallerini homblend + biyotit ± klinopiroksen ve titanit oluşturmaktadır. Benzer mineralojik bileşime sahip, bolca artık mafik kayaç kapanımları içerirler ve I-tipi granitoyid özelliğindedirler. K, Rb, Sr, Ba, Zr, Nb, Th, U, Rb/Sr, La, Ce konsantrasyonun yüksek, K/Rb ve Sr/Ba konsantrasyonları ise düşüktür. Bazı iz element içerikleri açısından volkanik yay çarpışma sonrası granitoyidlere benzerlik gösteren Çelebi Granitoyidinin, mineralojik-petrografik ve jeokimyasal özelliklerine göre, kıtasal kabuk ± manto malzemesinin bölümsel ergimesiyle oluştuğu ileri sürülebilir.
