AB  - Çalışma alanı Balıkesir-Dursunbey ileKütahya-Simav ilçeleri arasında yer almaktadır. Civanadağtüfleri üzerinde yapılan arazi ve petrografik çalışmalara göre, birimin alt (pomzayığışım fasiyesi) ve üst (ince taneli laminalı fasiyes) fasiyes olmak üzere ikifarklı fasiyesten oluştuğu belirlenmiştir. Alt fasiyes, metamorfik çakıliçerikli pomzaca zengin tüfler ile başlamakta olup, üst seviyelerde pomza velitik bileşen boyutu azalmaktadır. İnce taneli ve yer yer laminalanma gösterenüst fasiyes ise, pembe renkli, litik-vitrik tüf, vitrik tüfler ve beyazımsı grirenkli litik-vitrik tüfler ile başlamaktadır. Beyaz renkli kristal-vitrik tüfve vitrik-kristal tüf ile devam etmektedir. En üst seviyesi ise, yeşil renklibol biyotitli kristal-vitrik tüfler ile temsil edilmektedir. Tüfler, aglomeralarile son bulmaktadır. Civanadağ tüflerinin petrografik incelemelerinde saptanan pirojen mineraller; kuvars+sanidin +plajioklas +biyotit ±amfiboldür. Riyolit, dasit bileşimlikalkalkalen karakterli özelliğe sahip Civanadağ tüflerinin ana oksit, iz venadir toprak element içerikleri tüfün gelişiminde fraksiyonel kristallenmenin önemlibir rol oynadığını, bu kristallenmenin başlıca K-feldispat ve plajiyoklastarafından kontrol edildiğini göstermektedir. Ayrıca örümcek diyagramındakiyüksek K ve Rb içeriği, kabuk kirlenmesi ve magma karışımının varlığına işaretetmektedir.

N2  - The study area is located between Balikesir-Dursunbey and Kutahya-Simavdistricts. According to the field studies and petrographic studies on Civanadagtuffs, it is determined that this unit is formed by two different facies asUpper (fine-grained laminated facies) and Lower (pumice accumulation facies) facies.Lower facies begins with tuffs which are rich by pumice contains metamorphicgravel. Upper level of facies, size of pumice and lithic components decrease.The fine-grained laminated upper facies begins with pink-colored lithic-vitrictuff, vitric tuffs and whitish-gray lithic-vitric tuffs. The uppermost level isrepresented by abundant green coloured biotite crystal-vitric tuffs. Tuffs endwith agglomerates. Pyrogen minerals determined in the petrographicinvestigations of Civanadag tuffs; quartz +sanidine +plagioclase +biotite ± amphibole. Major, trace and rare earth element contents of Civanadagtuff, which is characterized by their rhyolite, dacite composition,calc-alkaline, show fractional crystallization process which is chieflycontrolled by K-feldspar and plagioclase. Also high K and Rb contents in thespider diagram indicate the presence of crustal contamination and magma mixing.
