Inverted fluvial features in the Aeolis-Zephyria Plana, western Medusae Fossae Formation, Mars: Evidence for post-formation modification
[1] The Aeolis and Zephyria Plana contain the western-most portion of the Medusae Fossae Formation (MFF), an enigmatic and extensive light-toned deposit located in the Martian equatorial region and dated from the Hesperian to Amazonian epochs. This area hosts a large population of sinuous ridges (SRs), interpreted as inverted fluvial features, formed by precipitation, indurated by chemical ceme...
متن کاملFluvial sedimentary deposits on Mars: Ancient deltas in a crater lake in the Nili Fossae region
[1] New spacecraft observations in the Nili Fossae region of Mars reveal two valley networks (!80 and !200 km long) that each formed distributary fans as they entered an ancient 40-km diameter impact crater. An outlet channel on the eastern crater rim, lying at an elevation above the fans, suggests these fans formed as subaqueous deltas in a crater lake. Water flowing in the valley networks ent...
متن کاملHiRISE images of yardangs and sinuous ridges in the lower member of the Medusae Fossae Formation, Mars
HiRISE images of the lower member of the Medusae Fossae Formation (MFF) were used to identify characteristics of two specific landforms that are well expressed in this particular geologic unit; yardangs and sinuous ridges. Yardangs are wind-eroded ridges that are usually confined to arid environments where the bedrock materials can be easily eroded by windblown sand. Yardangs are common in the ...

متن کاملDiscovery of alunite in Cross crater, Terra Sirenum, Mars: Evidence for acidic, sulfurous waters
Cross crater is a 65 km impact crater, located in the Noachian highlands of the Terra Sirenum region of Mars (30°S, 158°W), which hosts aluminum phyllosilicate deposits first detected by the Observatoire pour la Minéralogie, L’Eau, les Glaces et l’Activitié (OMEGA) imaging spectrometer on Mars Express. Using high-resolution data from the Mars Reconnaissance Orbiter, we examine Cross crater’s ba...
