Two examples of travertine bridges are observed at 8 to 15 m above stream level in the Lower Zamanti Basin, Eastern Taurids. Yerköprü-1 and Yerkoprü-2 bridges are currently being deposited from cool karstic groundwaters. The interplay
of hydrogeological structure, local topography, calcite-saturated hanging springs, algal activity and rapid downcutting in the streambed appear to have led to the formation of travertine bridges. Aeration through cascades and algal uptake causes efficient carbon
dioxide evasion that enhances travertine formation.
les sédiments piégés dans l'épikarst et l'endokarst et les datations isotopiques sur les spéléothèmes et les terrasses des travertins permettent de préciser les stades de creusement des canyons et les changements climatiques et environnementaux.
