Latitude-Dependent Mantle (in MOC) (with Stratigraphically Associated Periglacial Landforms)

  • Richard Soare
Living reference work entry


1–10 m-thick layer covering the surface of Mars in both hemispheres between 30 and 60° latitude, thought to be composed of water ice and dust, formed by means of airfall deposition and surface accumulation

The LDM refers to the continuous and meter-deep surface material that has been observed putatively in a global band from the mid- to the high latitudes (30–60°) of both Martian hemispheres. It is relatively smooth, shows a high albedo, and is thought to comprise ice-cemented dust. The LDM hypothesis is derived largely from multiple studies of MOC (mid- to high-latitude) images (~1.5–12 m/pixel). Putative periglacial landforms (PPLs) such as small-sized (and non-sorted) polygon-patterned ground, scalloped (thermokarst-like) terrain, and circular to subcircular mounds (possible closed-system pingos) also...
