Geology of the Güney Town district (Denizli)

Basement rocks is made of Eşme Formation which is composed of gneiss and schists of the Menderes Massif. In ascending order, Neogene sequence is composed of the Hamamçayı Member of Ahmetler Formation with uncormity on basement and Ulubey Formation which comformable with the Hamamçayı Member. Quaternary travertines and alluvions cover the lower units with unconformity. Blocky conglomerate, channel-fill conglomerate, pebbly sandstone, cross-bedded sandstone, volcanic sandstone, mudstone, calcareous mudstone, clayey-sandy limestone and clayey lignite and gypsum macrolithofacies have been idendified from Hamamçayı Member and pisolitic-gastropodal sandy limestone, silicified limestone and breccia limestone. Sandstones are dominantly litarenite. Limestones commonly are micrite, intraclastic micrite, bioclastic micrite, biomicrite, fenestral spaced biomicrite, algal micrite, peloidal micrite, intraclastic peloidal micrite, organic micrite, intrasparitic and intramicrite. Hamamçayı Member has been deposited in the meandering river system grifted with the fresh water shallow lacustrine and carbonate mudflats. Synsedimentary volcanism had been induced the sedimentation. Especially, karstification is prominent feature in the carbonate rock of the Ulubey Formation. U ve V shaped karstic walleys, circular and stepwise karstic structures and karstic collaps are common. Travertein formations are common in the U and V shaped karstic walley transitions.
