By simply touching speleothems, oils are left behind. Touching can also dull the color of speleothems, sometimes staining them. Touching can also stop the growth of speleothems. Since speleothems are formed with water, oil creates a barrier that does not allow dissolved minerals to continue to deposit.Why do stalagmites drip water?
Water dripping onto stalagmite A comes from the overlying limestone bed. No fissures can be seen in this limestone bed, and it is therefore likely that the stalagmite is mostly fed by diffuse flow, through either the limestone matrix or through very fine fractures.How heavy is a stalactite?

Stalagmites are often dated by the U-series disequilibrium technique, but ESR can be a substitute method for samples with detrital Th or a low U content. One of the first ESR dating studies (Miki and Ikeya, 1978) was on a stalagmite. Since then, ESR has been used to date stalagmites ranging in age from 2 to 100 Ka.Do stalagmites drip water?
A stalagmite is an upward-growing mound of mineral deposits that have precipitated from water dripping onto the floor of a cave. Most stalagmites have rounded or flattened tips. There are many other types of mineral formations found in caves.Do stalactites drip water?
