Using the data from the High Resolution Stereo Camera (HRSC) and the High Resolution Imaging Science Experiment (HiRISE), we conducted a quantitative geomorphological study of the inlet valleys of the Jezero paleolake. Results show that the strongest erosion is related to a network of deep valleys that cut into the highland bedrock well upstream of the Jezero crater and likely formed before the formation of the regional olivine-rich unit. In contrast, the lower sections of valleys display poor bedrock erosion and a lack of tributaries but are characterized by the presence of pristine landforms interpreted as fluvial bars from preserved channels, the discharge rates of which have been estimated at 103-104 m3s-1. The valleys' lower sections postdate the olivine-rich unit, are linked directly to the fan-deltas, and are thus formed in an energetic, late stage of activity. Although a Late Noachian age for the fan-deltas' formation is not excluded based on crosscutting relationships and crater counts, this indicates evidence of a Hesperian age with significant implications for exobiology.", "keywords": ["Geologic Sediments", "550", "landing site", "Extraterrestrial Environment", "Datasets as Topic", "Magnesium Compounds", "Mars", "01 natural sciences", "HRSC", "HiRISE", "[SDU.STU.PL]Sciences of the Universe [physics]/Earth Sciences/Planetology", "Taverne", "Exobiology", "0103 physical sciences", "Perseverance rover", "Off-Road Motor Vehicles", "Spacecraft", "fluvial landforms", "Fluvial deposits", " Sedimentology", " Landing site", " Mars", " Perseverance rover", "", "Landing site", "0105 earth and related environmental sciences", "Silicates", "500", "15.

In this article, we demonstrate the sequences of lake filling and delta formation and constrain the minimum life span of the Jezero paleo-lake from sedimentological and hydrological analyses. Two main phases of delta evolution can be recognized by utilizing imagery provided by the High Resolution Imaging Science Experiment (NASA Mars Reconnaissance Orbiter) and High Resolution Stereo Camera (ESA Mars Express): (1) basin infilling before the breaching of the Jezero rim and (2) the delta formation itself. Our results suggest that delta formation occurred over a minimum period of 90-550 years of hydrological activity. Breaching of the Jezero rim occurred in at least three distinct episodes, which spanned a far longer time-period than overall delta formation. This evolutionary history implies that the Jezero-lake floor would have been a haven for fine-grained sediment accumulation and hosted an active environment of significant astrobiological importance.", "keywords": ["Geologic Sediments", "Evolution", " Chemical", "550", "Extraterrestrial Environment", "[SDU.STU]Sciences of the Universe [physics]/Earth Sciences", "Mars", "Neretva Vallis", "15.
