Stalactite a cave it will drip down. When the solution comes into contact with air the chemical reaction that created it is reversed and particles of calcium carbonate are deposited. The reversed reaction is: An average growth rate is a year. The quickest growing stalactites are those formed by a constant supply of slow dripping water rich in calcium carbonate (CaCO) and carbon dioxide (CO), which can grow at per year. The drip rate must be slow enough to allow the CO to degas from the solution into the cave atmosphere, resulting in deposition of CaCO on the stalactite. Too fast
Amorphous calcium carbonate the ability to stabilize poorly soluble drug molecules in its extensive pore system and could also enhance the drug release rates of these drugs. Paleoclimate reconstruction: A better understanding of the transformation process from amorphous to crystalline calcium carbonate will improve reconstructions of past climates that use chemical and biological proxies. For example, the calibrations of the clumped C-O carbonate paleothermometer and understanding the origins and evolution of skeletal structures. Environmental remediation: Improving environmental remediation efforts through gaining insight into the roles of earth materials in biogeochemical cycling of nutrients and metals through better understandings of the properties of environmental
