Paleoflood events recorded by speleothems in caves

Abstract:
Speleothems are usually composed of thin layers of calcite (or aragonite). However,
cemented detrital materials interlayered between laminae of speleothemic carbonate have been also observed in many caves. Flowstones comprising discontinuous carbonate layers form due to flowing water films,while flood events introduce fluviokarstic sediments in caves that, on occasion,are recorded as clayey layers inside flowstones and stalagmites. This record provides a potential means of understanding the frequency of palaeofloods using cave records.In this work,we investigate the origin of this type of detritaldeposit in El Soplao Cave (Northern Spain). The age of the lowest aragonite layer
of a flowstone reveals that the earliest flood period occurred before 500 ka, though most of the flowstone formed between 422 +69/-43 ka and 400 +66/-42 ka. This suggests that the cave was periodically affected by palaeoflood events that introduced detrital sediments from the surface as a result of occasional extreme rainfall events,especially at around 400 ka.The mineralogical data enable an evolutionary modelfor this flowstone to be generated based on the alternation offload events with laminar flows and carbonate layers precipitation that can be extrapolated to other caves in which detrital sediments inside speleothems have been found.
