Speleothems typically form in limestone or dolomite solutional caves. Isotopic records from speleothems are an important source of information about past climates and, given the increase in the number of isotopeenabled climate models, are likely to become an important tool for climate model evaluation.

Written by two leading authorities in the field, it represents the state of the art in speleothem science, covering from the basic concepts on carbonates rocks to the use of speleothems as multiproxy archives of past climate. The excess calcium is then precipitated on the cave walls and ceilings to make up speleothems. When land is cleared above a cave, less water is retained in the soil and therefore less water seeps into the cave.
