Did Martian valley networks substantially modify the landscape?

Grau Galofre, Anna; Jellinek, A. Mark; Bahia, Rickbir Singh +2 more

Valley networks are ancient drainage systems incised on the southern hemisphere of Mars, and stand as evidence that liquid water once sculpted its surface. The duration of valley network activity and the sources of water are key questions in deciphering the timing of water stability on early Mars, but remain poorly constrained. In this study we ad…

Martian fan deposits: Insights on depositional processes and origin from mass balance survey

Hynek, Brian M.; Williams, Rebecca M. E.; Di Achille, Gaetano +2 more

Fan deposits located at the mouths of Martian valleys have been interpreted as indicators of wet conditions during Mars history. However, the processes, time and amount of water needed to carve the valleys and form the fans are still debated. Here we present a detailed morphometric and mass balance analysis of valleys and fan-shaped deposits using…
