  abstract = {{D}espite increasing knowledge on the orogenic phases of the {P}yrenees, the {N}eogene evolution of the range re-mains poorly constrained. {T}he central {P}yrenees, particularly the {A}riege {R}iver valley and its terrace systems and glacial extensions, are key to reconstructing {P}yrenean evolution during the {N}eogene. {H}owever, few terrace relics remain on the piedmont edges. {T}o overcome this limitation and temporally extend the dataset obtained from terraces, we focus on alluvium-filled horizontal epiphreatic passages developed in limestone karstic networks. {T}hese landforms record the transient position of former local base levels during the process of valley deepening, similar to fluvial terraces. {T}he alluvium fills of the studied caves in the {T}arascon-sur-{A}riege area, in the transition zone between the upper range and the piedmont, therefore enable the reconstruction of the geodynamic evolution of the {A}riege {R}iver valley. {A}ll studied caves are developed on at least eight levels. {B}ased on burial durations determined by {A}l-26/{B}e-10 and {B}e-10/{N}e-21 terrestrial cosmogenic nuclide dating of samples from epiphreatic levels, our results indicate {L}anghian to {M}essinian (similar to 13-5 {M}a) incision rates averaging 48 m {M}yr(-1). {H}owever, the obtained record does not allow us to accurately retrace the {P}liocene evolution of the area due to the lack of known caves at corresponding levels. {M}oreover, raised local base levels during glacial phases both make the re-cord more complex and call into question the methodological approach in terms of potential internal sediment remobilization and mixing related to implied re-flooding periods},
