What is is travertine a chemical sedimentary rock?

Travertine is a type of chemical sedimentary rock that is formed through the precipitation of carbonates from groundwater. It is composed of calcium carbonate (CaCO3) and other minerals like clay, silt, and iron. Travertine is usually found near mineral springs, hot springs, and limestone caves, where the water is saturated in calcium carbonate. As the water flows through the rock, it picks up dissolved minerals and deposits them as sediment when it evaporates, creating layers of travertine. Travertine is commonly used in construction, such as for countertops, flooring, and facades, due to its unique aesthetic qualities, including its ability to take on a polished, textured, or honed finish.
