  author={Vincent F. Chevrier and François Poulet and J. P. Bibring},
Images of geomorphological features that seem to have been produced by the action of liquid water have been considered evidence for wet surface conditions on early Mars. Moreover, the recent identification of large deposits of phyllosilicates, associated with the ancient Noachian terrains suggests long-timescale weathering of the primary basaltic crust by liquid water. It has been proposed that a greenhouse effect resulting from a carbon-dioxide-rich atmosphere sustained the temperate climate… 

The Case of the Lacking Carbonates and the Emergence of Early Life on Mars

The mineralogical characterization of Mars by different exploration missions, provides a new image of the earliest conditions that prevailed on the planet surface. The detection of extensive deposits

The environment of early Mars and the missing carbonates

Abstract– A model is presented in which the aqueous conditions needed to generate phyllosilicate minerals in the absence of carbonates found in the ancient Noachian crust are maintained by an early

Magmatic precipitation as a possible origin of Noachian clays on Mars

Hydrous clay minerals detected on the surface of Mars have been interpreted as indicators of the hydrologic and climatic evolution of the planet. The iron- and magnesium-rich clays described in

Geochemical Reservoirs and Timing of Sulfur Cycling on Mars

Sulfate-dominated sedimentary deposits are widespread on the surface of Mars, which contrasts with the rarity of carbonate deposits, and indicates surface waters with chemical features drastically

Contemporaneous deposition of phyllosilicates and sulfates: Using Australian acidic saline lake deposits to describe geochemical variability on Mars

Studies of the origin of the Martian sulfate and phyllosilicate deposits have led to the hypothesis that there was a marked, global‐scale change in the Mars environment from circum‐neutral pH aqueous

Geochemistry constrains global hydrology on Early Mars

Sulfur dioxide inhibits calcium carbonate precipitation: Implications for early Mars and Earth

Recent studies have suggested a role for sulfur dioxide (SO2) in maintaining relatively warm surface temperatures on early Mars. Here we show experimentally, that SO2 concentrations orders of



Phyllosilicates on Mars and implications for early martian climate

It is inferred that the two main families of hydrated alteration products detected—phyllosilicates and sulphates—result from different formation processes, which occurred during two distinct climatic episodes: an early Noachian Mars, resulting in the formation of Hydrated silicates, followed by a more acidic environment, in which sulphates formed.

Inhibition of carbonate synthesis in acidic oceans on early Mars

Examination of the feasibility of carbonate synthesis in ancient martian oceans using aqueous equilibrium calculations concludes that extensive interaction between an atmosphere dominated by carbon dioxide and a lasting sulphate- and iron-enriched acidic ocean on early Mars is a plausible explanation for the observed absence of carbonates.

Jarosite as an indicator of water-limited chemical weathering on Mars

It is concluded that the presence of jarosite combined with residual basalt at Meridiani Planum indicates that the alteration process did not proceed to completion, and that following jarosite formation, arid conditions must have prevailed.

Low oxygen levels in earliest Triassic soils

An earliest Triassic methane postapocalyptic greenhouse following the Permian-Triassic (P-T) extinction event was proposed on the basis of evidence of deeply weathered paleosols at high latitudes

Weathering of iron-rich phases in simulated Martian atmospheres

In order to simulate the weathering of primary phases likely to occur on the Martian surface, metallic iron α-Fe, magnetite, and pyrrhotite were aged in CO 2 + H 2 O or CO 2 + H 2 O 2 atmospheres at

Principal features of impact‐generated hydrothermal circulation systems: mineralogical and geochemical evidence

Any hypervelocity impact generates a hydrothermal circulation system in resulting craters. Common characteristics of hydrothermal fluids mobilized within impact structures are considered, based on

In Situ Evidence for an Ancient Aqueous Environment at Meridiani Planum, Mars

The geologic record at Meridiani Planum suggests that conditions were suitable for biological activity for a period of time in martian history.
