Ejecta features are classified based on their distance from the impact crater, the appearance of the ejected material, and the geomorphological characteristics of the terrain. Some common ejecta features include ejecta blankets, radial and concentric ejecta patterns, and secondary craters.

Ejected matter, especially from an erupting volcano. Volcanic ejecta usually includes volcanic glass, ash, and rock fragments.
Meteorite crater - Impact Process, Ejecta, Shockwaves: When an asteroidal or cometary object strikes a planetary surface, it is traveling typically at several tens of kilometres per second—many times the speed of sound. A collision at such extreme speeds is called a hypervelocity impact.
Mar 1, 2023 · Distal ejecta with non-radial distributions are an inherent product of planetary impacts, and their unobvious provenances could mislead stratigraphic interpretations and hamper age estimations ...
