travertine 也是一种钙质沉积岩,但通常更致密、层状明显,常用于建筑装饰;tufa 则更多孔、粗糙,多指自然形成的泉华。

Travertine is often polished for tiles, while tufa is left rough in natural landscapes.

limestone

limestone 是广义的石灰岩,可包括多种类型;tufa 特指由温泉或钙质水快速沉淀形成的多孔石灰岩,是 limestone 的一个子类。

All tufa is limestone, but not all limestone is tufa; tufa forms uniquely in aqueous environments.
