What are spelethems?

Answer 1

Speleothems are mineral formations that occur in caves, primarily composed of calcium carbonate, though other minerals can also be involved. They form through the deposition of minerals from dripping water, resulting in structures such as stalactites, stalagmites, and flowstones. These formations often develop over thousands to millions of years and provide valuable insights into geological and climatic conditions. Speleothems are also important in the study of cave ecosystems and paleoclimate research.
