A little about the video
Sea level affects the littoral morphology and structure in different ways. In coastal karst basins, dissolutional and depositional processes are strictly related to sea level variation. A great variety of karst-related geomorphological features and cave deposits exist above, below, and at sea level, and are extremely useful to study past changes of relative sea level. Within these, vadose speleothems such as flowstones and stalagmite, can document unequivocal maximum sea level constraints as well as record phreatic phases of sea level rise. Here we present a series of geochronological data from the eastern Mallorca and show the implication of relative sea level oscillations in the coastal karst evolution over the last kyr. We investigate a total number of twenty-two samples between flowstones and stalagmites from different paleokarst sites and coastal caves.

U-Th and radiocarbon dating of calcite speleothems from gypsum caves (Emilia Romagna, North Italy)

Comprehensive Guide to Family and Home Preparedness. Speleothems are mineral formations occurring in limestone caves, most commonly as stalagmites and stalactites, or slab-like deposits known as flowstones. They are composed primarily of calcium carbonate, precipitated from ground water that has percolated through the adjacent carbonate host rock.

Speleothems typically form in limestone or dolomite solutional caves. The usual definition of speleothem specifically excludes secondary mineral deposits in mines, tunnels, and other man-made structures. More than variations of cave mineral deposits have been identified. Calcareous speleothems form via carbonate dissolution reactions. As the lower pH water travels through the calcium carbonate bedrock from the surface to the cave ceiling, it dissolves the bedrock via the reaction:.
