Bu çalışmada Eosen yaşlı Kışlaköy (Narman/Erzurum) volkanik kayaçlarının minerolojik, petrografik ve mineral kimyası analizleri incelenmiştir. Elde edilen veriler doğrultusunda magmaların kristallenme esnasında etkili olan sıcaklık, basınç gibi fizikokimyasal özellikleri ile fizikokimyasal verileri jeolojik verilerle birleştirerek bu kayaçları oluşturan magmaların kabuktaki gelişimleri irdelenmiştir. Çalışma alanındaki başlıca birimler Eosen yaşlı Kışlaköy Volkaniti, Oligo-Miyosen yaşlı Oltu Formasyonu, Oligo-Miyosen yaşlı Alabalık Formasyonu ve Alüvyonlardan oluşmaktadır. Kışlaköy volkanik kayaçları volkanik fasiyes özelliklerine göre piroklastitler, dayklar ve lavlar olmak üzere üç başlıkta incelenmiş, genellikle bazalt bileşiminde ve başlıca plajiyoklaz (An49-85), klinopiroksen (Wo40-46 En41-50 Fs5-18), olivin (Fo68-75) ve Fe-Ti oksit minerallerden oluşmaktadır. Bu kayaçlar genel olarak hyalo-mikrolitik porfirik, glomeroporfirik, glomerofirik, mikrolitik porfirik, poikilitik, intersertal doku sergilemektedirler. İncelenen volkanitler; plajiyoklaz fenokirstallerinde halkalı zonlanma, elek dokusu ve kemirilme; klinopiroksenlerdeki yenme, kemirilme ve kalıntı merkezler gibi dengesizlik dokuları gözlenmiştir. Termobarometre hesaplamalara göre volkaniklerin kristallenme sıcaklığı 489-1247 0C arasında, basınç 0.5-4.7 kbar arasında değişmekte olup, bütün bu verilere bakılarak incelenen volkanik kayaçların orta-sığ kıtasal kabuk (~4-12 km) içerisinde yerleştiği söylenebilir.

This study was examined minerological, petrographic and mineral chemistry analyzes of Eocene aged Kışlaköy volcanic rocks (Narman / Erzurum). The data obtained suggest that the physicochemical properties of the magmas such as temperature, pressure, which are effective during crystallization, and physicochemical data were combined with geological data, and the development of the magmas forming these rocks in the crust was examined. The main units in the study area are Eocene aged Kışlaköy Volcanite, Oligo-Miocene aged Oltu Formation, Oligo-Miocene Trout Formation and Alluviums. Kışlaköy volcanic rocks have been examined under three headings as pyroclastics, dykes and lavas according to their volcanic facies characteristics, have compositionally basalt and mainly consist of plagioclase (An49-85), clinopyroxene (Wo40-46 En41-50 Fs5-18), olivine (Fo68-75) and Fe-Ti oxide. These minerals generally exhibit hyalomicrolytic porphyritic, glomera porphyritic, cumulative porphyritic, microlitic porphyritic, poikilitic, intersertal textures. The studied volcanics rocks, disequilibrium texture are observed such as oscillatory zoning, sieve texture and corrosion in plagioclase phenocrysts, zoning, resorbed cores and mantles, rounded crytals, and embayed rims in clinopyroxenes. According to thermobarometric calculations, volcanics have crystallization temperature and pressure values ranging from 489 to 1247 oC, 0.5 to 4.7 kbar respectively. It can be concluded that the studied volcanics were emplaced at mid to shallow crustal depths (~4-12 km).
