Petrography and petrology of the calc-alkaline Sarıhan Granitoid (NE Turkey): An example of magma mingling and mixing

Öz:
Doğu Pontidler (KD Türkiye) kuzey ve güney kuşağında değişik yaşlarda pek çok asidik sokulum mevcuttur. Sarihan Granitoyidi bunlardan biridir. Doğu Pontid güney kuşağında bulunan Maastrihtiyen yaşlı Sarihan Granitoyidi, genellikle orta dereceli metamorfik kayaçlardan oluşan Permo-Karbonifer öncesi yaşlı Pulur Masifi'ni, Dikmetaş konglomera üyesi ile başlayıp volkano-sedimanter kayaçlarla devam eden Liyas yaşlı Hamurkesen Formasyonu'nu ve kireçtaşı-kumlu kireçtaşından oluşan Malm-Geç Kretase yaşlı Hozbirikyayla Formasyonu'nu keserek yerleşmiştir. Arazi gözlemlerine göre yükselim-yerleşim modeli 'stoping' tipinde olan ve yaklaşık 40 km2 bir alanda ellipsoidal şekilde izlenen Sarıhan Granitoyidi genellikle kuvars-monzodiyorit, granodiyorit ve kuvars-diyoritten oluşmaktadır. Sokulum, volkanik ve silisleşmiş kireçtaşı ksenolitleri ile diyoritik mafik mikrogranülar anklavlar içermektedir. Orta taneli, poikilitik, monzonitik, anti-rapakivi ve bazende mirmekitik doku gösteren kalk-alkalin bileşimindeki pluton, %43-64 plajiyoklas, %6-18 ortoklas, %10-29 kuvars, %5-20 hornblend, %1-8 biyotit, %l-6 opak mineral ile apatit, titanit ve zirkon gibi tali mineraller ve kalsit, klorit ve serisit gibi ikincil mineraller içermektedir. Sokulumda tespit edilen bazı dokuların bulunması magma karışmasına (mixing),anklavların bulunması da magma karışmasına (mingling) işaret etmektedir. Sokulum % 65-67 SiO2, % 1.4-3.1 MgO, % 4.1-5.5 Na20 ve <1 $K_20/Na_20$ değerlerine sahiptir. 1 tipi ve metalümin özelliğindeki pluton, kafemik grup granitlerin özelliğini olan, sialik ve manto kökenli kaynakların karışımından türeyen melez kaynak özelliği sunmaktadır. Kalk-alkalin bileşimindeki pluton kalk-alkalin granodiyorit serilerin yönelimlerine karşılık gelmektedir. Harker diyagramındaki Sİ02'ye karşı Ti02, AI203, FeO, Fe2O3, MnO, MgO, CaO, P2O5, Ba ve Nİ değerleri azalırken Na20, K20, Rb ve Nb değerlerinin artması, plajiyoklas ve hornblend tarafından kontrol edilen kesri (fraksiyonel) kristallenmeyi işaret etmektedir. Bununla birlikte ana ve iz elementlerdeki düzensiz değişimler magma kirlenmesinden kaynaklanabilir. Kıtasal kabuğa göre normalize edilen iz elementlerden Zn, Rb, Sr, La, Pb, Th ve Zr değerleri zenginleşirken Ce, Cr ve Ni değerlerinde bir azalma söz konusu olup volkanik yay granitlerinin özelliklerini göstermektedir. Tektonik olarak pluton, volkanik yay granitlerinin özelliğini sunmaktadır. $^{87}Sr/^{86}Sr$ oranının 0.70504 olması magma kökenli kaynak ile kabuğun karışımından oluşan melez magma kökenine işaret etmektedir.
