The main objective of the research on its Quaternary lacustrine sediments was to reconstruct the evolution of Lake Balaton from its formation until today. One of the key parameters in answering this question is to retrace lake-level changes. There is a lot of evidence, such as sedimentological, mineralogical, geochemical, archaeological, etc. to reveal these changes. Each type is of different reliability depending upon the sensitivity of the lake to level change and to preservation of the traces of those changes as a result of geologic, climatologic or human factors. The average thickness of Quaternary sediments accumulated in Lake Balaton is 5 m. From the lake bottom toward the surface lacustrine sediments are constituted by clastic deposits, peat and calcareous mud with upward-increasing carbonate content (calcite, dolomite, Mg-calcite, protodolomite and aragonite).

Lithological variations, sedimentary features of the travertine and the underlying friable chalky carbonates and calcareous clays were described in the field. Four lithotypes and several microfacies types of travertine have been identified. The stratal pattern of travertine, distribution of lithotypes, the macrofauna, and the presence of microbial sediments suggests that the travertine was deposited in a shallow lake environment. The lake was fed by lukewarm springs from the central part (probably from Szentharomsag-ter [Szentharomsag Square] area), where the thickest travertine deposits are found. Direct evidence of cascade deposits or terraced tetarata deposits have not been found in the studied sections.

Micromorphological features, e.g. needle-fiber calcite, carbonate hypocoatings around pores, ferruginous precipitations and clay infillings in the paleosol and cavity fills indicate that in situ pedogenic processes were active in both layers. The presence of ferrihydrite in the A horizon of the paleosol also supports pedogenic alteration.

Several relics of architecture and sculpture from the Roman province of Pannonia and Medieval Hungary were made of this material, specifically from the quarries of the study area. Exploitation of the limestone opened the large, vertically-walled pools preserving the settlements of Paleolithic people in the loose sediments and the travertine cover: at Vertesszolos, remains of Homo erectus, and at Tata, habitations of Homo sapiens neanderthalensis were found in the travertine.
