Sulfates in Martian Layered Terrains: The OMEGA/Mars Express View
Abstract
The OMEGA/Mars Express hyperspectral imager identified hydrated sulfates on light-toned layered terrains on Mars. Outcrops in Valles Marineris, Margaritifer Sinus, and Terra Meridiani show evidence for kieserite, gypsum, and polyhydrated sulfates. This identification has its basis in vibrational absorptions between 1.3 and 2.5 micrometers. These minerals constitute direct records of the past aqueous activity on Mars.

Other aqueous minerals such as sulphates, chlorides and silicas are found in more localized regions of the Noachian and Hesperian crust.
“Other aqueous minerals such as sulphates, chlorides and silicas are found in more localized regions of the Noachian and Hesperian crust (Gendrin et al. 2005; Osterloo et al. 2010; Carter et al. 2013; Ehlmann & Edwards 2014).”
From The Climate of Early Mars (2016) · cites this paper as Gendrin et al. 2005
The paper reports sulfates in localized light-toned layered deposits dated to the Noachian and/or Hesperian (p. 2). It does not report detections of chlorides or silica: it says halite might be present but lacks a detectable spectral signature in these observations (p. 2). (LLM, conf=0.88)
Experimental — accuracy not yet measuredSulphates are abundant on Hesperian and Noachian terrain.
“The martian surface is sulfur-rich (Clark et al. 1976) and sulphates are abundant on Hesperian and Noachian terrain (Gendrin et al. 2005; Bibring et al. 2005; Ehlmann & Edwards 2014).”
From The Climate of Early Mars (2016) · cites this paper as Gendrin et al. 2005
The paper reports sulfate-rich layered deposits whose formation is dated to the Noachian and/or Hesperian epochs (p. 2). It also says that OMEGA detects sulfates in equatorial regions only in close association with light-toned layered deposits, not scattered across the surrounding terrain. Thus it supports abundance in particular deposits, but not across Hesperian and Noachian terrain generally. (LLM, conf=0.84)

- [9]9. The sulfates are identified through the use of band ratios. To map the sulfate areas, we use a methodology based on Green et al., IEEE trans. Geosc. Rem. Sens. 26 , 65 (1993). We then check that each spectrum of the resulting classification presents the absorption bands of interest.

“Orbiting spacecraft observations of thick sulfate sediments in Valles Marineris and other locations (Gendrin et al., 2005) indicate the presence of relatively cold (in some cases below 0 C) and acidic waters in the Hesperian or Amazonian (Okubo et al., 2008).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
