Solutional cave and most abundant solutional caves are located in limestone. Limestone caves are often adorned with calcium carbonate formations produced through slow precipitation. These include flowstones, stalactites, stalagmites, helictites, soda straws, calcite rafts and columns. These secondary mineral deposits in caves are called "speleothems". Limestone dissolves under the action of rainwater and groundwater charged with HCO (carbonic acid) and naturally occurring organic acids. The dissolution process produces a distinctive landform known as "karst", characterized by sinkholes, and underground drainage. Solutional caves in this landform—topography are often called karst caves. Lechuguilla Cave in New Mexico and nearby Carlsbad Cavern are now believed
Resava Cave formed by the sinking river in the limestone substrate. Cave formations are right at the entry. They are formed through the dissolving of the calcium carbonate. The color depends on the mineral through which the water flows: red from the iron oxide, white from the crystallized calcium and yellow from the traces of clay. The symbol of the cave is a massive stalagmite, tall and wide. After its appearance, it was named the Statue of mother with a child. The cave consists of 8 halls. Resava cave was accidentally discovered by the local shepherds in 1962. After being explored for
