Limestone caves are formed by erosion. Rainwater is slightly acidic and this erodes limestone. Can start off as rock eroding from a small underground aquifer and can become a large underground river. The rainwater that percolates through the ground and into the caves erodes the calcium in the limestone. Where it drips off the roof of the cave, some of the calcite is deposited and this eventually forms a stalicitite. Where it hits the floor of the cave it becomes a stalicmite. There are examples of Limestone caves open to the public in Co. Clare and Fermanagh in Ireland although there are many more cave systems in theses areas.

Limestone caves are the result of the weak carbonic acid in rainwater dissolving the limestone rock over millions of years. The limestone rock has cracks which the rainwater percolates through eventually forming underground streams and finally large caverns or caves. Some of the most spectacular in the UK are in Derbyshire and also in Chedder in Somerset.

Marble is formed by metamorphosed limestone. NOT the other way around. Limestone is formed by the accumulation of marine organisms that make their shells from calcium carbonate. It is found in lots of places, especially those that used to be or are still deep marine environments. It is used for lots of things. Construction, antacids, the white powder on chewing gum, etc, etc. Look up commercial uses for limestone (try wikipedia) and it should give you a good list.

im from indiana...and indiana is well know for our limestone.....a lot of great building...some in washington dc have been made out of indiana limestone......i havent heard of limestone cave...i always though limestone was layers ,or sheets of stone for lake beds, and river beds......to hold the water in, or to keep it from draining out....but limestone cave could be possibly in other regions...but not here in indiana
