Wray The region surrounding the Mawrth Vallis outflow channel on Mars hosts thick layered deposits containing diverse phyllosilicate minerals. Here we report detection of the Ca-sulfate bassanit...
متن کاملTerrestrial Analog Studies of Mawrth Vallis, Mars: the Painted Desert
Introduction: Mawrth Vallis, Mars, exhibits unique stratigraphy characterized by distinct phyllosili-cate units across an expansive region [1,2]. A potential analog for this site is the Painted Desert in Arizona, where striking profiles of clay and iron oxide units color the landscape [3]. Both sites contain multiple phyllosilicate units in similar stratigraphy across wide regions. We have acqu...
متن کاملPhyllosilicates in the Mawrth Vallis region of Mars
[1] OMEGA/Mars Express has discovered large outcrops rich in phyllosilicates in the region of Mawrth Vallis, Mars (around 20 W, 25 N). The region is located in Noachian highly cratered terrains, close to the limit of the Martian dichotomy, where the outflow channel Mawrth Vallis cuts the highlands. We have examined this region using OMEGA spectra of the surface from 0.9 mm to 2.6 mm, with spati...
متن کاملPhyllosilicate diversity and past aqueous activity revealed at Mawrth Vallis, Mars.
Observations by the Mars Reconnaissance Orbiter/Compact Reconnaissance Imaging Spectrometer for Mars in the Mawrth Vallis region show several phyllosilicate species, indicating a wide range of past aqueous activity. Iron/magnesium (Fe/Mg)-smectite is observed in light-toned outcrops that probably formed via aqueous alteration of basalt of the ancient cratered terrain. This unit is overlain by r...
متن کاملThe Mawrth Vallis region of Mars: A potential landing site for the Mars Science Laboratory (MSL) mission.
The primary objective of NASA's Mars Science Laboratory (MSL) mission, which will launch in 2011, is to characterize the habitability of a site on Mars through detailed analyses of the composition and geological context of surface materials. Within the framework of established mission goals, we have evaluated the value of a possible landing site in the Mawrth Vallis region of Mars that is targe...
