Abstract
The Devonian sequences of Eastern Taurides are divided into three formations in the previous works: Lower Devonian Ayı Tepesi, Middle Devonian Şafak Tepe and Upper Devonian Gümüşali Formations (Özgül et al, 1973; Metin et al, 1983; Yılmaz 2004; Göncüoğlu et al, 2005). The Upper Devonian Gümüşali formation of the eastern Taurides is a terrigenous-carbonate rock sequence about 600 m thick (Figure 1). Its basal portion is made up of dark grey limestones interbedded with shale or marly shale. The middle part consists of an alternation of limestone and shale with quartz sandstone and siltstone interbeds. The upper 85 meters is dominated by dark grey, silty-sandy, spiculitic limestones. Palaeontologic and sedimentologic data mainly indicate a shallow subtidal depositional environment. Late Devonian conodont and ostracod faunas were obtained from this formation.
