Hierve el Agua mountainside. The water has a temperature of . As the water runs down the rock face, it forms large stalactites similar to those found in caves. The flow of water from the spring varies significantly between the dry and rainy seasons. 95% of the surface rock formations are of calcium carbonate; however, lower layers of both rock and water currents are little known as they are sealed by the above layers. The calcium carbonate gives the formations a white or near white appearance, but other minerals that can be present in the water, such as silver, barium and iron can
Cap carbonate atmosphere, falling as a weak carbonic acid - acid rain. This would weather exposed silicate and carbonate rock, including readily-attacked glacial debris, which would release large amounts of calcium. When washed into the ocean, these precipitate to form distinctively textured layers of carbonate sedimentary rock. A heavily debated cap carbonate appears at the top of the Gaskiers glaciation, believed by many to be global in extent. Cap carbonate Cap carbonates are layers of distinctively textured carbonate rocks which typically form the uppermost layer of sedimentary sequences reflecting major glaciations in the geological record. The rising temperatures, and increased oceanic surface
