speleothemology

Speleothemology is the scientific study of speleothems, which are the mineral deposits found in caves. These formations, often referred to as cave formations or stalagmites and stalactites, are created over long periods by the slow deposition of minerals from water that drips or flows through the cave system. The primary mineral involved is calcite, a form of calcium carbonate, though other minerals like aragonite and gypsum can also form speleothems.

The study of speleothemology involves understanding the processes of cave formation, the hydrology of cave systems, and the geochemistry of mineral precipitation. Speleothemologists analyze the growth patterns, chemical composition, and isotopic signatures within speleothems to reconstruct past environmental conditions. This can include information about past climate, rainfall, temperature, and even atmospheric composition.

Speleothems exhibit a wide variety of forms, each with specific names such as stalactites, stalagmites, columns, flowstones, draperies, and helictites. The shape and size of a speleothem are influenced by factors like the rate of water seepage, the concentration of dissolved minerals, the cave's air circulation, and the underlying rock structure. Research in speleothemology contributes to our understanding of Earth's history, cave ecosystems, and the long-term geological processes that shape our planet. It is a multidisciplinary field drawing on geology, chemistry, hydrology, and paleoclimatology.
