Abstract

International audience; The Mars Science Laboratory rover Curiosity found host rocks of basaltic composition andalteration assemblages containing clay minerals at Yellowknife Bay, Gale Crater. On the basis of theobserved host rock and alteration minerals, we present results of equilibrium thermochemical modeling ofthe Sheepbed mudstones of Yellowknife Bay in order to constrain the formation conditions of its secondarymineral assemblage. Building on conclusions from sedimentary observations by the Mars Science Laboratoryteam, we assume diagenetic, in situ alteration. The modeling shows that the mineral assemblage formedby the reaction of a CO2-poor and oxidizing, dilute aqueous solution (Gale Portage Water) in an open systemwith the Fe-rich basaltic-composition sedimentary rocks at 10–50°C and water/rock ratio (mass of rockreacted with the starting fluid) of 100–1000, pH of ~7.5–12. Model alteration assemblages predominantlycontain phyllosilicates (Fe-smectite, chlorite), the bulk composition of a mixture of which is close to that ofsaponite inferred from Chemistry and Mineralogy data and to that of saponite observed in the nakhliteMartian meteorites and terrestrial analogues. To match the observed clay mineral chemistry, inhomogeneousdissolution dominated by the amorphous phase and olivine is required. We therefore deduce a dissolvingcomposition of approximately 70% amorphous material, with 20% olivine, and 10% whole rock component.

Abstract

International audience; Sedimentary rocks examined by the Curiosity rover at Yellowknife Bay, Mars, were derived from sources that evolved from an approximately average martian crustal composition to one influenced by alkaline basalts. No evidence of chemical weathering is preserved, indicating arid, possibly cold, paleoclimates and rapid erosion and deposition. The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions. Analyses of diagenetic features (including concretions, raised ridges, and fractures) at high spatial resolution indicate that they are composed of iron-and halogen-rich components, magnesium-iron-chlorine-rich components, and hydrated calcium sulfates, respectively. Composition of a cross-cutting dike-like feature is consistent with sedimentary intrusion. The geochemistry of these sedimentary rocks provides further evidence for diverse depositional and diagenetic sedimentary environments during the early history of Mars.

Abstract

We determined radiogenic and cosmogenic noble gases in a mudstone on the floor of Gale Crater. A K-Ar age of 4.21 ± 0.35 billion years represents a mixture of detrital and authigenic components and confirms the expected antiquity of rocks comprising the crater rim. Cosmic-ray–produced 3 He, 21 Ne, and 36 Ar yield concordant surface exposure ages of 78 ± 30 million years. Surface exposure occurred mainly in the present geomorphic setting rather than during primary erosion and transport. Our observations are consistent with mudstone deposition shortly after the Gale impact or possibly in a later event of rapid erosion and deposition. The mudstone remained buried until recent exposure by wind-driven scarp retreat. Sedimentary rocks exposed by this mechanism may thus offer the best potential for organic biomarker preservation against destruction by cosmic radiation.

Abstract

Geochemical data returned from the Mars Science Laboratory’s Curiosity rover over 1296 sols, has revealed a previously unforeseen martian geochemical complexity. Before Curiosity landed in Gale Crater, Martian SNC meteorite studies along with previous orbiter, rover and lander data showed Mars as being a predominantly basaltic planet with little magmatic differentiation. But through using ChemCam density contour plots to collate compositional data obtained by that instrument, we can identify 4 compositional end members in Gale sedimentary and igneous samples.
