Travertine

Description

A light-colored, porous rock composed primarily of Calcite. Travertine is a variety of Limestone formed from multilayered Calcium carbonate deposits in pools by the slow precipitation of mineral-rich spring water. The "holes" characteristic of travertine were produced by trapped Carbon dioxide bubbles during its formation. Plant residues are often layered with the calcite deposits resulting in large elongated, often interconnected rings in the stone. Very porous, spongy travertine is called Tufa. Travertine polishes to a matte finish. It is used as an interior and exterior building material. Thick deposit of travertine occur near Tivoli, Italy, and Mammoth Hot Springs in Yellowstone National Park. Banded travertine from Mexico is called Mexican onyx marble.
