Abstract

Several geothermal fields are located in a NE-SW trend along a structural lineament around the Sivas basin. By evaluating the rocks of the Late Miocene-Early Pliocene Kızılırmak Formation, it was determined that fissure axes developed within Ortaköy fissure-ridge-type travertines, and that the structural elements obtained from satellite images together with the fissures that form the fissure-ridge-type travertines are shear and tension fissures, and the NE-SW-oriented opening of the fissures, were a result of NW-SE-directed compression, which was also responsible for the formation of the Sivas Backthrust. Ground-penetrating radar studies have shown that the thickness of fissure fills within the fissure-ridge-type travertines of the Ortaköy geothermal field increase with depth, and that the hydrothermal fluids which brought about the formation of the travertines moved surfaceward via fissure systems. The results of U/Th radiometric dating indicate the age of the youngest and oldest travertine in the region
