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
Geology of the Grand Canyon area Limestone averages 505 million years old and is made of gray, thin-bedded limestone that was deposited farther offshore from calcium carbonate precipitates (see 3c in figure 1). The western part of the canyon has a much thicker sequence of Muav than the eastern part. The Muav is a cliff-former, thick. These three formations were laid down over a period of 30 million years from early-to-middle Cambrian time. Trilobites followed by brachiopods are the most commonly reported fossils in this group but well-preserved fossils are relatively rare. We know that the shoreline was transgressing (advancing onto land) because finer grade material
