Fluid expulsion in terrestrial sedimentary basins: A process providing potential analogs for giant polygons and mounds in the martian lowlands

摘要: Abstract On Earth, burial of fine-grained sediments in offshore passive margins (e.g., underwater fans and deltas) commonly results fluid expulsion features including large-scale polygonal fractures, mud volcanoes, pockmarks. Comparison resulting polygons volcanoes with giant high-albedo mounds the Chryse–Acidalia region Mars shows terrestrial martian to be similar size, morphology, geologic context, general co-occurrence within same basin. These similarities suggest that process may provide an analog could link Chryse Acidalia a single process. Moreover, while develop basins, these do not necessarily occur exactly locations those as they are independent responses compaction dewatering. Thus, does require have identical distributions. This is situation where extensively developed generally overlapping distributions, but each set places without other. enhanced by fact co-occur regional sense setting consistent model formation. Implications this impact our view role water depositional history lowlands.
