Which mineral precipitation governs speleothem (cave formation) growth rates?

💡 Explanation

The calcium carbonate saturation index determines speleothem growth by controlling calcium carbonate deposition from groundwater via a process called precipitation equilibrium, because greater saturation leads to faster deposition; therefore, index strength is central rather than another gradient.
