In the interior of the peninsula, the recharging water annually dissolves about 37.5 metric tons of calcite per 1 km2. When the groundwater has become saturated with calcite, little additional water-rock interaction occurs until the active mixing (dispersion) zone is reched near the coastline. As much as 1.2 mmol/L additional calcite can be dissolved in the brackish groundwater zone of dispersion. This indicates that if the total solution potential of the amount of water discharging at Xel Ha lagoon has focused within the lagoon area, the lagoon could be chemically incised in less than 3000 yr. -after Authors
