Dolomite also known as dolostone and dolomite rock is a sedimentary rock composed primarily of the mineral dolomite CaMg CO 3 2 Dolomite is found in sedimentary basins worldwide It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium rich groundwater Dolomite and limestone are very similar

The most common rock in Mammoth Cave is limestone Limestone is a sedimentary rock that allows cave passages to easily form because of its chemical makeup and ability to be dissolved by acidic groundwater Mammoth Cave s limestone formed about 330 million years ago at a time when a warm shallow ocean covered much of the southern United

The process of cave formation begins when the carbonic acid makes its way into the ground between the lime stone When this unfresh water passes through these lime rocks the tiny particles of lime are made into homogenous Solution Restored in shape and thus an endless series of rock merging continues for thousands of years

The cycle usually begins with the emplacement or eruption and eventual erosion of igneous rocks and their subsequent deposition as sediments From here the rocks may be pushed further into the Earth and incorporated into the molten inner layers or they may be brought to the surface over time as sedimentary rocks
