one of the most frequently used stones in modern architecture,
and is commonly seen as facade material, wall cladding, and
flooring. Architect Welton Becket was one of the most frequent
users of travertine, incorporating it extensively into many if
not most of his projects. The entire first floor of the Becket-
designed UCLA Medical Center has thick travertine walls. rock
travertine is a natural chemical precipitate of carbonate
minerals; typically aragonite, but often recrystallized to or
primarily calcite; which is deposited from the water of mineral
springs (especially hot springs) or streams saturated with
calcium carbonate. pure, travertine is white, but often is brown
to yellow due to impurities. When carbon dioxide-rich water
percolates through rocks in limestone areas, the water dissolves
the limestone and becomes saturated with it. When the water
resurfaces later, the sudden drop in pressure and the change in
temperature cause the water to release the carbon dioxide gas,
much like fizzy drinks. The ca
