Geochemical constraints on the presence of clay minerals in the Burns formation, Meridiani Planum, Mars

  author={C. Cino and E. Dehouck and S. McLennan},
Abstract Burns formation sandstones, deposited by aeolian processes and preserved at Meridiani Planum, Mars, contain abundant sulfate minerals. These sedimentary rocks are thought to be representative of a sulfate-rich geological epoch during late Noachian – early Hesperian time that followed an earlier clay-rich epoch. Twenty Burns formation targets, abraded by the Rock Abrasion Tool (RAT) and for which alpha-particle X-ray spectrometry (APXS) and Mossbauer spectroscopy data are available… Expand

Geochemistry constrains global hydrology on Early Mars
Abstract Ancient hydrology is recorded by sedimentary rocks on Mars. The most voluminous sedimentary rocks that formed during Mars' Hesperian period are sulfate-rich rocks, explored by theExpand
Clay coatings on sands in the western Qaidam Basin, Tibetan Plateau, China: Implications for the Martian clay detection
Abstract The widespread clay minerals on Mars have been detected using orbital data using near-infrared spectroscopy, which is limited by its shallow detection depth, low recognition precision andExpand
Aluminosilicate haloes preserve complex life approximately 800 million years ago
These deposits lack metazoan fossils even though they share fossilization conditions with younger BST deposits that are capable of preserving non-mineralizing metazoans, so metazoan fossils were probably absent from sedimentary environments before approximately 800 Ma. Expand
Modern Iron Ooids of Hydrothermal Origin as a Proxy for Ancient Deposits
An exceptional, unique finding of a still active deposit of submillimetric iron ooids, under formation at the seabed at a depth of 80 m over an area characterized by intense hydrothermal activity off Panarea, a volcanic island north of Sicily (Italy). Expand
Stability and fate of ferrihydrite during episodes of water/rock interactions on early Mars: An experimental approach
The presence on the surface of Mars of ferrihydrite, a nanocrystalline iron oxide species, has long been suspected from spectroscopic observations and is further suggested by recent results from theExpand
Geological Evidence of Planet‐Wide Groundwater System on Mars
Only the deepest basins considered in this study, those with bases deeper than −4000 m in elevation below the Mars datum, intercepted the water‐saturated zone and exhibit evidence of groundwater fluctuations, significantly increases the chance that biosignatures could be buried in the sediment.

New simulants for martian regolith: Controlling iron variability
Abstract Existing martian simulants are predominantly based on the chemistry of the average ‘global’ martian regolith as defined by data on chemical and mineralogical variability detected by orbitingExpand

Elemental Geochemistry of Sedimentary Rocks at Yellowknife Bay, Gale Crater, Mars
The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions during the early history of Mars. Expand
Provenance and diagenesis of the evaporite-bearing Burns formation, Meridiani Planum, Mars
Abstract Impure reworked evaporitic sandstones, preserved on Meridiani Planum, Mars, are mixtures of roughly equal amounts of altered siliciclastic debris, of basaltic provenance (40 ± 10% by mass),Expand
A volcanic environment for bedrock diagenesis at Meridiani Planum on Mars
An alternative model for diagenesis of Meridiani bedrock is proposed that involves deposition of volcanic ash followed by reaction with condensed sulphur dioxide- and water-bearing vapours emitted from fumaroles, which invokes an environment considerably less favourable for biological activity on Mars than previously proposed interpretations.

Mineralogical record of the redox conditions on early Mars
Abstract Sulfates and Fe-oxides identified on the martian surface by orbital and in situ missions indicate that oxidizing conditions have existed on early Mars, at least locally and/or episodically.Expand
Ancient Aqueous Environments at Endeavour Crater, Mars
Rocks on the rim of the Noachian age Endeavour crater are investigated, where orbital spectral reflectance signatures indicate the presence of Fe+3-rich smectites, which would have been more favorable for prebiotic chemistry and microorganisms than those recorded by younger sulfate-rich rocks at Meridiani Planum.
