Definition

  1. (1)

    As a structural unit: a very degraded complex crater found on icy satellites that formed very early in the satellite’s history, noted for its lack of relief.

     
  2. (2)

    As a descriptive/albedo unit: circular patches on icy satellites generally higher in albedo than their surrounding terrains, exhibiting little topographic relief (Smith et al. 1979b).

Description

Palimpsests are large, circular, low-relief impact scars appearing as circular, generally bright patches on Ganymede and Callisto (and perhaps elsewhere). The edges are circular and locally lobate on a 10 km scale (Jones et al. 2003). These structures lack rims but can have internal, concentric ridges (Patterson et al. 2010).

Surface Units of Palimpsests

  1. (1)

    Central plains (Jones et al. 2003)

    Corresponding unit: Bright central lobate unit (Moore et al. 1998); smooth central unit (Kadel et al. 2000).

    Description: Central plain forms the inner floor of palimpsests, extending out...
