Definition
Isolated groups of small craters, generally consisting of 10 or more craters from 10 m to a few km diameter (Figs. 1, 2). They often overlap, are presumed to have formed simultaneously, and are interpreted as craters formed by the impact of ejecta from a large impact.
Secondary crater cluster near Ma’adim Vallis (D = ~10 km, 20°S, 178°E). Scale bar 2 km. CTX: B05_011732_1597_XI_20S181W (NASA/JPL/MSSS)
