Conical landforms on Mercury and Mars -indicators of volatile release

International audience Molards are cones of debris that result from the disaggregation of ice-cemented blocks transported by mass movements. Recently, the origin of molards has been directly linked to permafrost degradation on Earth. We have found candidate molards in crater ejecta on Mercury and Ma...

Description
Summary:International audience Molards are cones of debris that result from the disaggregation of ice-cemented blocks transported by mass movements. Recently, the origin of molards has been directly linked to permafrost degradation on Earth. We have found candidate molards in crater ejecta on Mercury and Mars, which by analogy we link to volatile loss post-emplacement.
