Magma interaction recorded in plagioclase zoning in granitoid systems, Zigana Granitoid, eastern Pontides, Turkey

Öz:

Bileşimsel zonlanma ile karakterize olan plajiyoklaz kristalleri Zigana Granitoyidi'nde (ZG), KD-Türkiye tipik olarak gözlenmektedir. Kuvars + plajiyoklaz + K-feldspat + hornblend + biyotit + piroksen + magnetit + ilmenit denge kristaleşmesi sunan zonlu plajiyoklaz kristalleri salınımlı (oscillatory) zonlanma gösterirler. Kristal boyları 3 ile 6 mm arasında değişen zonlu plajiyoklaz kristalleri çoklukla oval biçimli olup, normal lata biçimlilerden daha büyüktürler. Zonlu plajiyoklazlar petrografik olarak, tamamen zonlu ve merkezi süngerimsi kenarı zonlu kristaller olmak üzere iki ana grupta toplanmışlardır. Zonlu kristallerin bileşimleri An23 (oligoklaz) ile An70 (labradorit) arasındadır. Salınımlı zonlu plajiyoklaz kristalleri kuvvetli $Ca^{2+}Leftrightarrow Na^+, Al^{3+}Leftrightarrow Si^{4+}$ ve zayıf $Fe^{3+} Leftrightarrow Si^{4+}$ sübsitüsyon mekanizması ile kontrol edilirler. Plajiyoklazların $Fe_20_3^{top}$ (% ağ.) konsantrasyonu, An içeriği ile artış sunar. Zonlu kristallerin petrografik, kenardan kenara kimyasal değişimleri ve mol % An içerikleri ile $Fe_20_3^{top}$ konsantrasyonları arasındaki pozitif ilişki, Zigana Granitoyidi'nin (ZG) oluşumu sırasında felsik magma odasına sürekli bir mafik injeksiyonun varlığına ve dolayısıyla magma etkileşiminin ağırlıklı magmatik olay olabileceğini yansıtmaktadır.
