Onyx stone is a type of travertine, mineralogically derived from calcite (CaCO₃), characterized by a banded appearance and ornamental qualities. Although geologically classified within travertine formations, it differs due to its distinct colored bands and potential for decorative use. Its colorful appearance results from the precipitation of calcium carbonate carried by cold bicarbonate-rich groundwater as it emerges to the surface, in environments containing various metal ions such as iron and

Denizli travertine is a sedimentary rock formed by the deposition of calcium bicarbonate-rich hydrothermal waters emerging onto the Earth’s surface along fault lines in Denizli Province, Türkiye. These travertines, noted for their cream, brown, and reddish tones, are extracted from quarries in areas such as Ballık, Kocabaş, Yenicekent, and Gölemezli and are particularly distinguished by their linear structures known as “water paths.”Formation ProcessDenizli travertine is a sedimentary rock forme

Kuzalan Waterfall is a waterfall located in the Black Sea Region of Türkiye, within the province of Giresun. It has a height of approximately 20 metres. The waterfall flows from a slope featuring travertine formations over the Aksu Stream. The travertines in the region have formed through the precipitation of dissolved calcium carbonate from groundwater. Kuzalan Waterfall lies within the boundaries of Kuzalan Waterfall Nature Park. The area is studied for its geomorphological structure hydrologi
