Purpose & Scientific Principle
The exhibits demonstrate the principle of carbonate deposition to form rocks through modeling scenes and electromechanical interactive devices, allowing the audience to personally experience and understand the process and principles of rock formation, and learn about the process of carbon storage and carbon sequestration in karst carbon sinks.
How to Operate
The deposition of stalagmites and stalactites is caused by the dissolution of soluble rock by rainwater. It flows to the cave with the water. Due to the change of conditions during the migration of saturated or supersaturated karst water, part of the carbon dioxide in the water body overflows and turns into calcium carbonate for deposition.
The formation of stalactites often takes tens of thousands or hundreds of thousands of years. Due to their long formation time, stalactites have important research value for ancient geological investigations. The main component of stalactites is calcium carbonate, which reacts with water and carbon dioxide under certain conditions to form calcium bicarbonate that is soluble in water. When the water with dissolved calcium bicarbonate flows or drips, the temperature changes, and the soluble calcium bicarbonate decomposes to form insoluble calcium carbonate. As a result, stalagmites and stalactites of different shapes appear. They are accumulated over millions of years and are not formed in an instant.
The exhibits mainly take the form of carbonate scenery boxes and interactive installations of dripping water, allowing the audience to experience and understand the process of rock formation.
