Travertines are terrestrial carbonates precipitated in the vicinity of, often fault-controlled, thermal springs in extensional and transtensional sedimentary basins. In these settings, faults and fissures act as circulation and mixing paths of carbonate-enriched thermogenic and meteoric fluids from which travertines precipitate at the surface. Therefore, travertine successions provide key information about the interplay between faulting, deposition, climate and fluid flow. This study investigates the travertine succession in the Miocene Levač Basin, the peripheral basin of the Morava corridor located at the interference zone between the Dinarides and the southernmost Carpathians. We analyzed the sedimentology, composition, U-Pb age (LA-ICP-MS) and relation to the faulting of the travertines to reconstruct the spatiotemporal evolution of the feeding hydrothermal system. We aim to use the high resolution record of the travertine to improve controls on sedimentation and faulting in Levač Basin and finally to elucidate the mechanisms controlling the Morava Corridor evolution during Miocene.
