tufa, a rock formed by the localized precipitation of calcium carbonate, typically in association with springs, caves, river beds, and lake edges. It should not be confused with the marine limestone of the Loire region known in French as tuffeau, nor with the widespread non-calcareous volcanic deposit called tuff that is much more relevant to viticulture.
