The Coexistence Of The Silica Oversaturated (Alkos) And Undersaturated Alkaline (Alkus) Rocks In The Kortundag And Baranadag Plutons From The Central Anatolian Alkaline Plutonism, E Kaman/Nw Kırşehir, Turkey, Nazmi̇ Otlu, Durmuş Boztuğ

Turkish Journal of Earth Sciences

Baranadağ and Kortundağ plutons, outcropping in the Kaman-Kırşehir region, constitute the important members of the Central Anatolian post-collisional alkaline plutonism. The Baranadağ pluton comprises only one lithodem called Baranadağ quartz monzonite, whereas, the Kortundağ pluton consists of four mapable units such as Hamit quartz syenite, Durmuslu nepheline-nosean-melanite porphyritic syenite, Bayındır nepheline-cancrinite syenite, and Çamsarı quartz syenite. Among these units, the Baranadağ quartz monzonite and Hamit quartz syenite cut the metamorphics of the Kırşehir Block. On the other hand, Durmuslu, Bayindir and Çamsarı are emplaced in both the Hamit quartz syenite and the metamorphics. The Baranadağ quartz monzonite, Hamit quartz syenite …
