A complex and multiproxy investigation was carried out in the last years including descriptions of new profiles and from all profiles granulometry, stabile isotope investigation, diffuse reflectance spectroscopy, magnetic susceptibility, luminescence and radiocarbon dating, amino acid stratigraphy. The distribution of different types of secondary carbonates was studied systematically. Macro-, meso- and micromorphology of the paleosols were used to make a clear identification of the different units and to identify the changing environment during and after the soil formation. The paleosols and the loesses are exposed in different parts of the former brickyard, partly even in different paleogeomorphological positions but in the western wall of the quarry, the whole loess-paleosol succession could be identified with all paleosols in a continuous section. The correlations of this new profile with the type sections showed a high degree of similarity based on the MS curve and the pedogenic character of the macroscopically similar paleosol. The other proxies and the absolute ages also support the correlation of the loess and paleosols located in distinct parts of the quarry.

The statistical analyses of the results and the precise determination of the elevation and gradient of the paleosols from different outcrops provide a complex understanding of the environmental development of the last 350 ka at Basaharc.

The research was funded by the Hungarian NRDIO K119366 project.
