Afyon Metasedimanter grubu'nda felsik Metavolkanitlerin petrografik ve jeokimyasal özellikleri

Afyon Metamorfitleri baskın olarak sedimanter kökenli litolojilerden oluşmaktadır. Alt ve Üst Metamorfitler olarak iki alt gruba ayrılan Afyon Metamorfitleri Orta / Üst Devoniyen - Üst Permiyen yaşlı Anadolu Platformu 'na ait karbonatlı seriler tarafından açılı diskordansla örtülür. Doğanlar şistleri, Çakmak kuvarsiti ve Sandıklı porfiroyidi (felsik metavolkanit) Alt Metamorfite ait litofasiyeslerdir. Deliktaş metakonglomerası, Ballıca filliti ve İscehisar mermeri ise, Üst Metamorfite ait litofasiyesleri oluşturur. Afyon Metamorfitleri içindeki felsik metavolkanitler meta-tüf ve meta-riyolit olarak tanımlanan iki tür kayaçtan oluşmaktadır. Afyon güneybatısında Alaca Tepe ve Bozçal Köyü çevresindeki felsik metavolkanitler ile Sandıklı batısında yüzeylenen "Sandıklı porfiroyidi" metamorfizma, mineralojik-petrografik ve jeokimyasal açıdan oldukça benzer özellikler göstermektedir. Sandıklı Porfiroyidi ve Afyon Metamorfik istifindeki felsik metavolkanitlerin Afyon Metamorfitlerinde Alt Metamorfiti etkileyen ilk metamorfizmanın ürünü anateksitik türevler olduğu, daha sonra gelişen ve Üst Metamorfiti etkileyen ikinci bir metamorfizma sonucu bölgesel foliasyon kazandıkları saptanmıştır. Geç evrede gelişen kataklastik deformasyonlar felsik metavolkanitleri milonit, protomilonite ve blastomilonit olarak adlandırılan kayaçlara dönüştürmüştür. Jeokimyasal olarak felsik metavolkanitler, yüksek $SiO_2$ içeriğine sahip (%73-79), normatif korund (c), A/CNK>1.1 değerleri ile peralumino karakter ve lökokratik bileşim, S-tipi granitoyidlere ve Kıta İçi Magmatik (WPG) kökene işaret etmektedirler.
