Friable Layered Deposits

Living reference work entry


Distinctive, low-latitude layered unit that drapes underlying terrain and has then been modified by aeolian erosion, on Mars.


A subset of inferred sedimentary rocks (Mars).

Related Terms

Notes on Terminology


Malin and Edgett (2000) defined mantles or mantling deposits as “surficial sedimentary deposits of smooth texture (at spacecraft image pixel scales of 1.5 to 20 m) and locally uniform thickness that appear to drape all but the steepest topography. Mantles show morphologies similar to terrestrial loess and primary air fall tephra deposits. Unlike dunes or thick sand sheets, mantles do not appear to have involved ground transport and interaction with local topography. Mantles are generally...
