Concentric Crater (Moon)

Reference work entry
DOI: https://doi.org/10.1007/978-1-4614-3134-3_64

Definition

An impact crater with one or more concentric ridges on the crater wall and/or crater floor with a central depression (Trang et al. 2011).

Synonyms

Description

Generally, concentric craters tend to have a central depression within the concentric ridge. A break in slope or a depression may exist between the crater wall and the concentric ridge.

Morphometry

There are 114 concentric craters with diameters between 2 and 28 km (median, ∼8 km) (Trang et al. 2011, in prep.). Concentric craters have shallower depths than fresh craters of the same diameter.

Subtypes

End-members of lunar concentric craters (Trang et al. 2011, in prep.):
  1. (1)

    A crater with a continuous smooth concentric ridge, displaying a V-shaped, circular valley between the crater wall and the concentric ridge. Example: Hesiodus A (Fig. 1).

     
  2. (2)

    A crater with a concentric ridge partitioned into smaller hills or domes. The concentric ridge displays a V-shaped, circular valley between...
