Travertine is a carbonate rock formed from gushing hot springs. The airy, porous material indicates an abundance of air bubbles moving through the rock as it solidified. While this characteristic is normally reserved for igneous rocks, travertine is unique in that it forms as a result of rapidly dropping pH levels.  This sample is useful in lessons on sedimentary petrology and geothermal systems. Each piece is approximately 1" long and comes in a labeled plastic bag.
