Definition

Ejecta deposit morphology displaying an unusually extensive, thin, and sinuous outer deposit beyond the normal layered ejecta blanket (Barlow and Boyce 2012, 2013; Barlow et al. 2014).

Category

A type of layered ejecta

Synonyms

Quasi-multiple layer ejecta (Barlow and Boyce 2008)

Description

An outer ejecta layer beyond an inner single-layer, double-layer, or multiple ejecta. It terminates in a “flame-like” sinuous edge, which typically becomes discontinuous (Barlow and Boyce 2008, 2013; Barlow et al. 2014; Boyce et al. 2014; Fig. 1).
