Central Mound (Secondary) Crater
A secondary impact crater with a well-developed central mound present in the crater floor, usually formed by the low-velocity impact of clustered ejecta fragments from a primary impact crater. The central mound is different from the central peak in a complex crater. These craters usually occur in the forms of clusters and chains in the distal ejecta ray deposits of the primary impact craters, but sometimes these are isolated. The size of central mound secondary craters depends on the size of the parent primary craters.
A type of secondary crater.
