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 contains calcium atoms coordinated by 6 oxygen atoms, in aragonite they are coordinated by 9 oxygen atoms. The vaterite structure is not fully understood. Magnesium carbonate MgCO has the calcite structure, whereas strontium and barium carbonate (SrCO and BaCO) adopt the aragonite structure, reflecting their larger ionic radii. Calcite, aragonite and vaterite are pure calcium carbonate minerals. Industrially important source rocks which are predominantly calcium carbonate include limestone, chalk, marble and travertine. Eggshells, snail shells and most seashells are predominantly calcium carbonate and can be used as industrial sources of that chemical. Oyster shells have enjoyed recent recognition as a
