These partitions separate isolated bodies of soluble rock called compartments. Speleogenetically each compartment will behave as a small impounded-karst until the partition becomes breached. Breaches through partitions, portals, allow water, air and biota including humans to pass between sections of caves that were originally isolated. %K impounded karst %K speleogenesis in steeply dipping limestones %K Australia %U http://www.speleogenesis.info/archive/publication.php?PubID=3256&Type=publication
