The association between bubble trails and folia: a morphological and sedimentary indicator of hypogenic speleogenesis by degassing, example from Adaouste Cave (Provence, France)

Abstract

Bubble trails are subaqueous features in carbonate caves, which are made by the corrosion of ascending carbon dioxide bubbles.Folia are calcite deposits resembling inverted rimstone dams in saturated pools. Based on morphological studies in Adaouste Cave(Provence, France) and on studies elsewhere in the world, we propose a new genetic model for folia, close to the model of Green(1991). The association of bubble trails and folia, occurring on overhanging walls, is interpreted to be an indicator of hypogenicdegassing occurring just below the water table. The association
