Travertine occurrences in the Canibazli village area exist at the western edge of the Gediz Graben, comprising the Turgutlu Neogene basin. The "Carnbazli travertine" was classified into two main groups based oil physical, mineralogical and petrographic properties. Occurrences of travertine are probably due to faulting between the Palcozoic units of Menderes Massif and the Pliocene Kanlitepe Formation. Group I travertine is horizontal and oriented NE-SW and NW-SE, whereas Group 11 travertine occurrences are oriented E-W direction. The Carnbazli travertine is a fissure-ridge type. Travertine continues to develop both in fissures and on the topographic surface as bedded deposits. Layered travertine is deposited on both surf aces of fissures. It develops either symmetrically or asymmetrically with respect to the centre of the fissure. Kinematical analyses of listric normal fault measurements demonstrate that NNE-SSW extension occurred. The Carnbazli travertine in the Gediz Graben has been deposited by hydrothermal waters rising through fracture systems, probably related to an active listric normal fault developed in the north of the study area.
