Kanger Ghati National Park Madarkonta and Kodri Bahar. These are Kotamsar cave, Kailash Cave, Dandak Cave, Devgiri Cave. Many other caves were also discovered in the national park. These caves have very fine structures of dripstones i.e. stalactites and stalagmites. Chemically these formations are recrystallized calcium carbonate. These structures have taken million of years to form. Kotamsar and Kailash caves are opened for tourists and other caves are closed for tourists. Only those caves which have openings have been discovered in the National park. There are many caves which have no opening and they are yet to be discovered. As approaches to most of
Calcium carbonate ingredient in many household cleaning powders like Comet (cleanser) and is used as a scrubbing agent. In 1989, a researcher, Ken Simmons, introduced CaCO into the Whetstone Brook in Massachusetts. His hope was that the calcium carbonate would counter the acid in the stream from acid rain and save the trout that had ceased to spawn. Although his experiment was a success, it did increase the amount of aluminium ions in the area of the brook that was not treated with the limestone. This shows that CaCO can be added to neutralize the effects of acid rain in river ecosystems.
