Unflashed geothermal waters in Iceland are invariably just saturated with calcite. Upon flashing the water always becomes supersaturated, especially during the early stages of flashing. Thus flashing will lead to calcite precipitation. It is believed that the rate of precipitation bears a positive relation to the degree of supersaturation and the water temperature. Accordingly, precipitation ...
