2017-6-20  The main lamination type of travertine is plane, consisting of stromatolitic microfacies with iron oxide (in the form of hematite, limonite, and magnetite), manganese, and also around 5% fragmental calcite (Bagherpour et al. 2014). Figure 3 shows the studied travertine rock in two samples of thin sections. Geological evidence has shown that the rocks are formed by tectonic-magmatic activities in

Cleaning Travertine Do's Don'ts How To Clean

2021-6-8  This stone is formed by underground rivers, subterranean springs and other water sources that carry mineral elements. These elements, specifically calcium carbonate form multiple layers to result in a new stone that is smooth and hard. This stone is travertine. It is a porous natural stone.

Geochemistry and Stable Isotopes of Travertine from

Travertine deposits in Deir Alla, Suwayma, and Az Zara areas were investigated. Mineralogy, geochemistry, stable isotopes and age dating indicate the presence of low-Mg calcite, with minor quartz components. The variable isotope (δ13C and δ18O) signatures indicate dependence on water temperature and water/rock isotopic exchange. In contrast, the high δ13C values in some travertine

2012-9-13  Accordingly, production rate was calculated as 18.75 m 2 /h in travertine, 9 m 2 /h in natural stone and 12 m 2 /h in marble. Mean cutter end consumption was calculated as 0.264 p/m 2 . It was observed that use of the machine, particularly in natural stone quarries, resulted in production of a larger number of blocks at a lower cost per unit time.
