Cave minerals | SpringerLink
The mineralizing solutions in caves are the seeping and flowing waters. Cave water is a dilute, low-temperature solution, containing mainly the ions Ca 2+, Mg 2+, Na +, HCO − 3, SO 2− 4, and Cl −. Sodium and chloride are usually minor constituents. Minerals that can be formed in caves are, therefore, limited to phases containing these six ...
