Concentric crater fill

A concentric crater fill is a landform where the floor of a crater is mostly covered with a large number of parallel ridges. [1] It is common in the mid-latitudes of Mars, [2] [3] and is widely believed to be caused by glacial movement. [4] [5] Areas on Mars called Deuteronilus Mensae and Protonilus Mensae contain many examples of concentric crater fill.

Concentric crater fill is when the floor of a crater is mostly covered with a large number of parallel ridges. [1] Concentric crater fill is common in the mid-latitudes of Mars. [2] [3] It is thought to be a result of glacial movement. [4] [5] Sometimes boulders are found on concentric crater fill; it is believed they fell off crater wall, then were transported away from the wall with the movement of the glacier. [6] [7] Erratics on Earth were carried by similar means. Based on accurate topography measures of height at different points in these craters and calculations of how deep the craters should be based on their diameters, it is thought that the craters are 80% filled with mostly ice. That is, they hold hundreds of meters of material that probably consists of ice with a few tens of meters of surface debris. [8] [9] The ice accumulated in the crater from snowfall in previous climates. [10] [11] [12] Concentric crater fill, like lobate debris aprons, and lineated valley fill are believed to be ice-rich features. [13]
