Gullies on Mars: A Review

Sinuous gullies on Mars : Distribution, mechanical properties and consequences for gullies formation

Recent gullies are erosional landforms developed on hillslopes in recent Martian time (less than 10 My). The nature of the fluid that created the erosion was initially considered as debris flows, but this is still under discussion. Indeed, hypotheses invoking only dry granular slides explain many characteristics of the gullies channels, their size, length, presence of levees and terminal deposi...

The Formation and Evolution of Youthful Gullies on Mars: Gullies as a Late- Stage Product of Mars’ Most Recent Ice Age

Introduction: The discovery of youthful gullies on Mars [1] provided strong evidence for short-duration flow of liquid water within the last several million years, an era not generally considered conducive to the stability of liquid water at the surface [2]. Given average conditions below the melting point for all of Mars and the apparent correlation between bed-rock layering and gully alcoves,...

Dickson) Gullies are extremely young erosional/depositional systems on Mars that have been carved by an agent that was likely to have been comprised in part by liquid water [Malin, M.C., Edgett, K.S., 2000. Evidence for recent groundwater seepage a...
