The Kahtepe Formation has been defined as mudstone, wackestone, packstone, and grainstone according to its microfacies characteristics. The source of the terrestrial input in the Kahtepe limestone samples demonstrates the semi-humid climate region and the Al/Ti ratios stress that the terrestrial input is fluvial rather than eolian. The source of the terrestrial input observed in the Kahtepe limestone samples is predominantly felsic but of mixed origin. Major and trace element properties of the Kahtepe limestones show insignificant diagenetic alteration (Mn/Sr < 0.46), and a significant amount of terrestrial input at some levels. The K/Rb ratios (0.031-0.061) of the Kahtepe limestone samples are quite low and do not indicate any metamorphism effect. The Kahtepe Formation was deposited in a carbonate shelf (marginal sea) environment in largely oxic conditions, which includes patch reefs in places, where there is a stream inflow at some stages and where weak organic matter can be preserved.eninfo:eu-repo/semantics/openAccessCarbonate ShelfGeochemical CharacteristicsKahtepe LimestoneConference Object
