Which phenomenon influences speleothem formation during limestone dissolution?

💡 Explanation

Speleothem formation accelerates via localized precipitation of calcium carbonate because the dissolution of limestone creates calcium-rich groundwater; therefore, carbonate precipitates as dripstone (stalactites or stalagmites) deposits rather than all dissolving due to continuous saturated flow in the karst system.
