Özet

Modem travertine deposits are observed in the Sicakcermik hot springs located northwest of Sivas, central Anatolia. They are the carbonate deposits of crustal (spongy) and/or alabaster-textured formations controlled by both organic and inorganic processes. The structures formed under the influence of inorganic processes include the accumulations an the fissure and joint ridges. These structures are adjacent to the hot water emergence spots representing the points of rapid hot water flow and sudden release of CO2. The structures developed under the influence of organic processes form in areas at relatively farther distances from the hot water emergence points. These structures were described to be "waterfall or cascade deposits"; "terrace-mound travertines"; and "shallow lake fans" by different researchers. They are recognized in the field by special identifying trails such as manganous-ferrous travertine shrubs resembling ivy, siliceous stromatolites, and ferrous pisoids, 3 to 12 mm in diameter.
