Pamukkale (Cotton Castle), in the west Anatolian sector of the Aegean extensional province, is so named because snow white travertines are accumulating there. Travertine deposition at Pamukkale, one of Turkey's most important tourist destinations, has been in progress for at least the last 400 000 years, and has partially overwhelmed the Roman city and necropolis of Hierapolis. The travertine originates from hot waters that emerge at 35-56-degrees-C from open fissures and at least one fault zone. The five principal morphological varieties of travertine mass are: (1) terraced-mound travertines; (2) fissure-ridge travertines; (3) range-front travertines; (4) eroded-sheet travertines; and (5) self-built channel travertines. The first two varieties are similar to those reported from well known travertines at Tivoli, east of Rome, and Mammoth Hot Springs, Wyoming, but the last three varieties have not previously been reported.
