Characterization Of The Depositional Environment Of Phreatic Overgrowths On Speleothems In The Littoral Caves Of Mallorca (Spain): A Physical, Geochemical, And Stable Isotopic Study, Liana Marie Boop

USF Tampa Graduate Theses and Dissertations

Phreatic overgrowths on speleothems (POS) are one of many sea-level proxies available to Quaternary geologists in Mallorca; these carbonate encrustations form at the air-water interface in cave passages flooded with brackish water. POS are ideal for reconstruction of western Mediterranean sea level because they are widespread in Mallorca's caves, can be precisely dated by U-series methods, constrain sea-level stands to sub-meter elevation, and are well preserved and accessible in the subterranean environment.

This research investigates the POS depositional environment, which is relatively understudied compared to the other proxies used for sea-level reconstructions. This disparity has led to assumptions on many …
