Cave formations are called speleothem, from the Greek word spelaion, cave and thema meaning deposit. Almost all of them are made of calcite, the crystal of calcium carbonate. Different minerals and different movements in the water account for an incredible variety of cave formations.
Limestone caves (AKA caverns) can be defined as natural cavities that are formed under the earth's surface. It can range from stretching to a few meters to stretching for miles in depth and length. They are found deep in the rocks and in some parts of the cave light has still not found its way.talagmites are formations which rise from the surface of the cave. Stalactites are formations which hang from the top of a cave. Flow stones are layers like formation because of the flow of the water. Given below are pictures of speleothems in the form of stalctites, stalgmites and flow stones.
