This limestone can be origin either from biological materials like dead corals and mollusks, or in some cases the limestone can be precipitated directly from the seawater...


As the rainwater fell through the atmosphere, it would react with carbon dioxide in the atmosphere. After the rain fell into the soil on the crest of the Maya Mountain, the water would absorb additional carbon dioxide from decaying plant material. The rainwater turns into a weak acid, which then reacts with the limestone rock eroding away creating caves."
