Abstract

The geology and the mineralogy of the clay beds (Doganhisar clays) located southeast of Doganhisar (central Anatolia, Turkey) were studied. Rock units found in and adjacent to the Doganhisar clay beds include metamorphic rocks of pre-Triassic age of the Sultandaglari Massif, the Miocene Ayaslar Formation and the Pliocene Doganhisar Formation as well as alluvium The Lower (?)-Middle Cambrian-Lower Ordovician Caltepe Formation forming the base of the metamorphic rocks is composed of recrystallized limestone and dolomite. The upper Cambrian-Lower Ordovician Sultandede Formation conformably overlies the \cCaltepe Formation. The Middle-Upper Devonian Engilli Formation unconformably overlies the Sultandede Formation and consists predominantly of metaquartzite. It is conformably overlain by the Lower-Middle Carboniferous Kirazli Formation. It is vertically and laterally graded upward in to the Lower-Middle Carboniferous Harlak Formation. Neogene cover units consist of alluvial fan and lacustrine deposits. Metamorphic rocks have undergone regional metamorphism under low grade metamorphic condition and three phases of deformation during the Alpine orogeny. X-ray diffraction (XRD) and chemical analysis were used to study the clay mineralogy. Illite and kaolinite, with lesser amount of chlorite dominate the mineral composition.
