This area contains segments of normal faulting and scarp boundary, both related to two phases of crustal collapse with perhaps two different mechanisms. Chaotic collapse of ambiguous (volcanic?) origin might be comparable with the formation of ancient caldera complexes at Arabia Terra. Scientists have long suspected that the valleys of Xanthe Tera were formed by water erosion.
