The circular collapsed structural units in the surroundings of the chaotic terrain on Mars provide information about the formation and development of the chaotic terrain. Examined were their distribution and morphological statistics in the Xanthe Terra region. The features suggest that they should be collapsed impact crates, and the collapse should occur independently against the depth of former crater fill and its buried floor, which indicates the origin of the collapse is located in deeper region. From these aspects, old crater could work as a water collecting system which the crater cracking network provide efficient path for the ground water.
