Active remote sensing by laser scanning (LiDAR) has markedly improved the mapping of a cave environment with an unprecedented level of accuracy and spatial detail. However, the use of laser intensity simultaneously recorded during the scanning of caves remains unexplored despite it having promising potential for lithological mapping as it has...

This review explores the potential for establishing valley incision chronologies from alluviumfilled cave systems, and covers a total of 30 case studies since 1997. Caves in limestone develop very fast (~10^4 years) when conditions for bedrock solution are optimal, and many contain alluvium deposited by allogenic sinking streams, preserving the...

Hypogenic caves, linked to carbonate rock dissolution due to CO 2-and H 2 S-rich ascending deep waters, represent more than 10% of karstic networks worldwide; a proportion that increases as these systems are better constrained. However, interaction between hypogenic and epigenic processes is still poorly understood, especially since the...
