A stalagmite (from the Greek "stalagma" (""), "drop" or "drip") is a type of
speleothemthat rises from the floorof a limestone cavedue to the dripping of mineralized solutions and the deposition of calcium carbonate. . If these formations grow together, the result is known as a column.
When touring caves with stalactites and stalagmites you might be requested to not touch the
rock formations. This is generally because the formation is considered to still be growing and forming. Since the rock buildup is formed by minerals solidifying out of the water solution onto the old surface, skinoils can disturb where the mineral water will cling, thus affecting the growth of the formation. Oils and dirt from the hands can also stain the formation and change its colour permanently.
Stalagmites can also form in
lava tubes, although the mechanism of formation is much different. Stalactites and stalagmites can also form on concreteceilings and floors, although they form much more rapidly there than in the natural caveenvironment.
