The Most Common, Beautiful and Adventurous Cave Type is a Limestone Cave

A limestone cave is most likely to contain beautiful cave formations. Also, the deepest and longest caves in the world are of this type, making them some of the most adventurous . But how are these caves formed?

Limestone is mostly made up of the mineral calcite (calcium carbonate). Most limestone was formed on ancient ocean floors, the calcite coming from the shells of marine organisms. Limestone is very soluble, meaning it is easily dissolved. Rain water picks up carbon dioxide in the air and a weak solution of carbonic acid is formed. This water can dissolve limestone over time, creating a cave.

The same water that dissolved the calcite in the limestone can deposit the calcite in other areas of the cave, creating cave formations known as speleothems. These are the stalactites, stalagmites and other formations commonly found in this type of cave.

Recently, it has been discovered that the well-known caves of Carlsbad Caverns and Lechuguilla Cave were not formed from carbonic acid but from sulfuric acid. It was discovered that oil-eating microorganisms deep within the earth produce hydrogen sulfide that rose up and mixed with ground water producing sulfuric acid. It was this sulfuric acid that dissolved the limestone forming the caves.

Either way, because the soluble limestone is partially dissolved and carried away, these are a type of solutional cave. Less common solutional caves are formed in other types of rock like chalk, marble or gypsum.

Often limestone caves are named caverns. What's the Difference? They are really the same thing. The name cavern is often used for very large caves or caves that contain large rooms like the Big Room in Carlsbad Caverns. This is the largest cave room in the USA.

So where do we find limestone caves? They're in many areas of the world, so you have a lot to choose from when planning your next adventure.
