Water and concretions
0
0
The formation of concretions is related to the presence of water, its flow, the height and the mode of its fall. If the flow rate is too high, stalactites do not have time to develop and remain small while thick and massive stalagmites are formed. If it is very weak, it gives birth to fine and fragile fistulas. Plaque crystallizations can occur in calcium bicarbonate supersaturated waters. If the water circulation stops, the concretions do not evolve anymore.
