Limestone caverns form when slightly acid groundwater seeping through limestone rocks dissolves a hole in the rock. Over time the hole increases in size forming caves that are sometimes miles long. The groundwater carries the dissolved calcite away in solution and deposits it in other caves as a limestone formation.

We have tons of cool mines in the Sierra - careful for bad air (CO2 pools), especially in limestone caves. Luckily the limestone quarries we sleep in, don't have any (toxic) gas as there are many many shaft and ventilation holes or entranes/exits. I have a gas detector, but don't have to bring it in for these types of quarries.

How to determine if a rock is limestone

Add 120ml of 20 per cent hydrochloric acid to 800ml of tap water. Ensure you add the hydrochloric acid to the tap water and not the other way around. Drip some of the solution on the rock. Observe the rock. If you see fizzles and bubbles, the rock is likely limestone. If the scratch leaves an imprint, it is likely the rock is limestone.

Limestone Characteristics – PerfectGranite

Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate). The primary source of this calcite is usually marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors as pelagic ooze (see lysocline for information on calcite dissolution).
