Mapping Subsurface Interfaces in Eastern Amazonis Planitia Using SHARAD Data

The SHARAD instrument on Mars Reconnaissance Orbiter detects multiple sets of buried interfaces in Eastern Amazonis. The interfaces extend for hundreds of kilometers and are generally horizontal or slightly dipping, with the exception of one area that may be a filled depression. These interfaces may represent the base of lava flow units that lie on a lessdense material such as regolith or porous volcanic deposits.
