Compositional variations, zoning types and petrogenetic ımplications of low-pressure clinopyroxenes in the neogene alkaline volcanic rocks of northeastern Turkey

Doğu Pontidlerde (Kuzeydoğu Türkiye) yüzeyleyen Neojen yaşlı alkalin volkanitlerin farklı kayaç serilerindeki iri ve orta boyutlu klinopiroksen kristalleri, ana magmanın kökeni yanında, onun kristallenme şartlarının ve gelişim tarihçesinin değişik aşamalarını kaydetmiştir. Kristal kimyası çalışmaları, her bir serideki klinopiroksenlerin büyük oranda dokusal ve bileşimsel benzerlik sunduklarını ve ortak bir petrojenetik geçmişe sahip olduklarını ortaya koymuştur. İncelenen klinopiroksenler göreceli olarak yüksek Mg numarasına (0.68–0.95), değişebilir Al2O3 (1.3–9.6 %wt), düşük TiO2 (

Kuzeydoğu Türkiye neojen yaşlı alkalin vokanik kayaçlarındaki düşük basınç klinopiroksenlerinin bileşimsel değişimleri, zonlanma türleri ve petrojenetik anlamları

Clinopyroxene phenocrysts and microphenocrysts in different series of the Neogene alkaline volcanic rocks from the eastern Pontides (NE Turkey) record various stages in the crystallization conditions and evolution history of the alkaline melt as well as its origin. Crystal chemical studies reveal that the clinopyroxenes in each rock series show strong textural and compositional similarities, which all reflect a common petrogenetic affinity. They have relatively high Mg-numbers (0.68–0.95), variable Al2O3 (1.3– 9.6 wt%), low TiO2 (
