Les résultats des études sédimentologiques, minéralogiques et géochimiques des travertins de Bet Shean, tendent à prouver que cette région, entre 45 000 et 22 000 B.P. était caractérisée par un climat plus humide que le climat actuel.
The diatom populations were examined in Cratoneurion associations on a slope travertine deposit in Belgian Lorraine. The floristic list (48 taxa), where the genus Cymbella is dominating (14 taxa), consists mainly of calciphilous and/or aerophilous
Hungarian geomorphological surfaces were elevated into various positions through tectonic activity. Some were buried before and during the Neogene. Some show paleokarst surfaces. Accumulated fluvial terrace-series are found. Travertine horizons
