英文摘要 | Deltas have been long considered a constraining element to reconstruct the water level of an ancient ocean that may have once occupied the northern lowlands of Mars, and just recently this hypothesis started to be challenged. We investigate this hypothesis and present a global inventory of fan shaped features showing typical deltaic traits across the entire Martian surface. For each element we provide descriptive details and classifications based on morphology, location, and relation with characterizing environmental features. In this catalogue of 162 deltas, we identified only six having high potential to constrain an oceanic paleo-shoreline. Nonetheless, age and location of these candidates display discrepancies with what was previously suggested from independent datasets about shoreline age and locations. Our analyses hence indicate that deltas alone are insufficient to delineate a globally consistent ancient oceanic shoreline, but they have the potential to locally constrain the water level both in space and time. |
