A rare landform : Yerköprü travertine bridges in the Taurids Karst Range, Turkey

Auteur :
BAYARI, C.S.

Description :
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.
