Neogene stratigraphy of the southern Hisarcık - Emet (Kütahya)

In the study area, widespread exposure of Tertiary and Quaternary deposits and volcanics are observed. Pre-Tertiary rocks are composed of units of Paleozoic and Mesozoic age.Tertiary deposits, which occur in Early Miocene aged alluvial fan deposits, starts with Kürtköyü formation. It occure terrestrial conglomarate levels. Early Miocene lacustrine sediments of Yeniköy formation, have an extensive distribution in the study area. The unit consists of alternating sequence of marl, sandstone, siltstone, crystallised limestone and claystone. There is also in places lens shaped, bluish gray - pale white coloured, medium bedded intercalated pumiceous tuff in the unit. Coal seams are of economic importance in the unit. Fluvial, well sorted sandstone which belonging to Çatak formation overlying comformably Yeniköy formation. The unit is stratigraphically overlain by fluvial Kızılyar formation which contain poorly consolidated angular - coarse grains (generally dominated lacustrine pebbles). Akdağ volcanic rocks which resulted from Miocene volcanism, are represented by basalt and rhyolite. Dereköy basalt is spherical weathered and has vugs filled with secondary calcite, which are alligned parallel to the flow lines. The youngest unit in the investigated are, is Travertine.
