Geological, Petrographical and Geochemical Properties of Pyroclastic Rocks in the Civanadag Region (Gugu-Balikesir), NW Turkey

Abstract

The study area is located between Balikesir-Dursunbey and Kutahya-Simav districts. According to the field studies and petrographic studies on Civanadag tuffs, it is determined that this unit is formed by two different facies as Upper (fine-grained laminated facies) and Lower (pumice accumulation facies) facies. Lower facies begins with tuffs which are rich by pumice contains metamorphic gravel. Upper level of facies, size of pumice and lithic components decrease. The fine-grained laminated upper facies begins with pink-colored lithic-vitric tuff, vitric tuffs and whitish-gray lithic-vitric tuffs. The uppermost level is represented by abundant green coloured biotite crystal-vitric tuffs. Tuffs end with agglomerates. Pyrogen minerals determined in the petrographic investigations of Civanadag tuffs; quartz +sanidine +plagioclase +biotite ± amphibole. Major, trace and rare earth element contents of Civanadag tuff, which is characterized by their rhyolite, dacite composition, calc-alkaline, show fractional crystallization process which is chiefly controlled by K-feldspar and plagioclase. Also high K and Rb contents in the spider diagram indicate the presence of crustal contamination and magma mixing.
