Bill Minarik#Calcite can form when cool groundwater warms as it rises to the surface. Calcium carbonate exhibits inverse solubility -it's less soluble in warmer water. As a result #tufa deposits can form -like those at Mono Lake. A nice write up of groundwater carbonate deposits at:

Flowstone, Travertine And Tufa — Canada (Ontario) Beneath Our Feet
In this note, I (Andy Fyon) describe some of the field and geochemical characteristics of flowstone, travertine and tufa. Theses are calcium carbonate deposits that are precipitated by mineral springs.
