Morphology of rimstone pools at Pamukkale, Western Turkey, 1995, Ekmekci Mehmet Gunay Gultekin, Simsek Sakir

Phototrophic Microorganisms of the Pamukkale, 1997, Pentecost Allan, Bayari Serdar , Yesertener Cahit
The travertines at Pamukkale contain a diverse assemblage of phototrophs: 17 species of cyanobacteria, 16 diatoms, and 5 Chlorophyceae. Two communities were recognized on the active travertines: (1) surficial mats dominated by filamentous cyanobacteria, particularly Lyngbya (Phormidium) laminosum forming soft weakly mineralized layers to 10 mm thick, and (2) a predominantly endolithic assemblage, also dominated by cyanobacteria developing 2-5 mm below the travertine surface. The distribution of these communities is determined largely by water flow and the degree of desiccation. Two further communities are briefly described from nondepositing areas. Most of the active travertine consists of alternating layers of micrite and sparite 0.25-0.75 mm in thickness, which probably result from short-term fluctuations in water flow rather than diel events (photosynthesis, temperature). The presence of needle-fiber calcite in surface samples suggests that evaporation of water may play some part in travertine formation. The phototrophs appear to influence the travertine fabric only locally, where the surficial growths contain strings of calcite crystals ad-hering to the filaments, forming irregularly laminated layers. The hot-spring water is believed to be contaminated with sewage and agricultural effluent, but there was no evidence to suggest that this is currently affecting the travertine deposits. The water is supersaturated with respect to calcite when it contacts the travertine, and precipitation is primarily the result of carbon dioxide evasion. Water chemistry and discharge measurements indicate a total travertine deposition rate of 35 tonnes per day.

Pamukkale (Hirapolis) : un site de travertins hydrothermaux exceptionnel de Turquie, 2002, Nicod, Jean
Pamukkale (Hierapolis): An outstanding site of hydrothermal travertines in Turkey - These travertines result from the deposit of carbonates near the hydrothermal springs, on the main active fault zone on the northern border of the Denizli basin (W Turkey). Their high mineralised water, rich of CO2 of geothermal origin, accumulate limestone in the fissure ridges and in the cascades on the front of the old travertines balcony, building up in it flowstone and rimstone dams. This site is particularly important as much for the archaeological and palaeoenvironmental researches as the palaeoseismic and neotectonics regional data.

SMALL-SCALE TERRACES AND ISOLATED RIMSTONE POOLS ON STALAGMITES IN CAVES EXHIBIT STRIKING SIMILARITY TO LARGE-SCALE TERRACE LANDSCAPES AT HOTSPRINGS, 2009, Dreybrodt Wolfgang, Gabrovek Franci
We report on sinter terrace forms on the centimetre scale observed on the top and at the base of a stalagmite in kocjanske jame (kocjan caves). These exhibit connected rimstone dams, forming a net-like pattern with active water pools inside. The form is similar to those seen at the large travertine terraces, which form by precipitation of calcite from spring waters highly supersaturated with respect to calcite. In contrast to these patterns we have also found isolated sinter basins with dimensions of a few centimeter on stalagmite-like structures in the cave Dimnice, Slovenia. Similar basins a few meters wide are a tourist attraction in Pamukkale, Denizli, Turkey. The observed features have grown from supersaturated solutions of calcium carbonate in laminar flow. Large-scale landscapes originate under conditions of turbulent flow. Some ideas are presented why, in spite of the clear difference in flow, the shapes are similar on all scales.
