Impact crater ejecta morphology displaying one continuous deposit with a sinuous edge, often terminating in a distal ridge (rampart).


A type of  layered ejecta


 Flower ejecta;  Pancake ejecta; Single lobe ejecta (SLE); Single lobe rampart crater

    Single layer  rampart (ejecta)

  2. (2)

    Single layer  pancake ejecta
