Term Tufa deposits
Definition

Sedimentary deposit that forms around a calcareous groundwater source, consisting of calcium carbonate (CaCO3), which is generated by the dissolution of calcium bicarbonate. It is found mainly in limestone regions, where it fills in cavities, forms stalactites and stalagmites and cements surface gravel, forming calcareous conglomerates. When in the vicinity of hot springs, tufa forms a type of limestone called travertine.


The Dominican Republic has travertine reserves in the provinces of Barahona and San Juan. It is extracted from mines in the form of large blocks to be used in the construction industry.
