Question

What are Swallow holes, Uvalas, Dolines, Travertines, Tufa, dripstones?

Answer 1

1. Swallow holes: It is a depression in the ground communicating with a subterranean passage (especially in limestone) and formed by solution or by a collapse of a cavern roof.
2. Uvalas: It is a local term used by people in some regions in Croatia, Bosnia and Herzegovina, Montenegro, and Serbia. In geoscience, it denotes a closed karst depression, a terrain form usually of elongated or compound structure and of larger size than that sinkholes.
3. Dolines: Dolines are funnel-shaped depressions of the ground surface formed by solution in limestone regions.
4. Travertines: Travertine is a form of limestone deposited by mineral springs, especially hot springs. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave
5. Tufa: It is a variety of limestone formed when carbonate minerals precipitate out of ambient temperature water
6. Dripstones: Rock deposited by precipitation from dripping water such as that which forms stalactites and stalagmites.
