New observations at Erebus crater (Olympia outcrop) by the Mars Exploration Rover Opportunity between sols 671 and 735 (a sol is a martian day) indicate that a diverse suite of primary and penecontemporaneous sedimentary structures is preserved in sulfate-rich bedrock. Centimeter-scale trough (festoon) cross-lamination is abundant, and is better expressed and thicker than previously described examples. Postdepositional shrinkage cracks in the same outcrop are interpreted to have formed in… Expand

Paleoclimate of Mars as captured by the stratigraphic record in Gale Crater
A kilometers-thick sedimentary sequence in Gale Crater exhibits stratigraphic changes in lithology that are consistent with transitions in aqueous and climatic conditions purported to be global inExpand
Sulfate-Rich Eolian and Wet Interdune Deposits, Erebus Crater, Meridiani Planum, Mars
This study investigates three bedrock exposures at Erebus crater, an ~ 300 m diameter crater approximately 4 km south of Endurance crater on Mars. These outcrops, called Olympia, Payson, and Yavapai,Expand
Deposition, exhumation, and paleoclimate of an ancient lake deposit, Gale crater, Mars
The observations suggest that individual lakes were stable on the ancient surface of Mars for 100 to 10,000 years, a minimum duration when each lake was stable both thermally (as liquid water) and in terms of mass balance (with inputs effectively matching evaporation and loss of water to colder regions).

Diverse Lithologies and Alteration Events on the Rim of Noachian-Aged Endeavour Crater, Meridiani Planum, Mars: In-Situ Compositional Evidence
We report the results of geological studies by the Opportunity Mars rover on the Endeavour Crater rim. Four major units occur in the region (oldest to youngest): the Matijevic, Shoemaker, Grasberg,Expand
Hypotheses for the origin of fine-grained sedimentary rocks at Santa Maria crater, Meridiani Planum
En route to Endeavour crater, the Mars Exploration Rover Opportunity embarked on a short but significant campaign at Santa Maria crater during sols 2450–2551. Santa Maria crater is a relatively youngExpand

Reconstruction of eolian bed forms and paleocurrents from cross‐bedded strata at Victoria Crater, Meridiani Planum, Mars
Outcrop exposures imaged by the Opportunity rover at Victoria Crater, a 750 m diameter crater in Meridiani Planum, are used to delineate sedimentary structures and further develop a dune-interduneExpand
Mars has an extensive, long-lived sedimentary record that is complimentary to the terrestrial record, bearing both first-order similarities and first-order differences. The igneous record is composedExpand


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. Expand

Analyses of outcrops created by the impact craters Endurance, Fram and Eagle reveal the broad lateral continuity of chemical sediments at the Meridiani Planum exploration site on Mars. ApproximatelyExpand
Two Years at Meridiani Planum: Results from the Opportunity Rover
Observations from microscopic to orbital scales indicate that ancient Meridiani once had abundant acidic groundwater, arid and oxidizing surface conditions, and occasional liquid flow on the surface. Expand
Stratigraphy and sedimentology of a dry to wet eolian depositional system, Burns formation, Meridiani Planum, Mars
Outcrop exposures of sedimentary rocks at the Opportunity landing site (Meridiani Planum) form a set of genetically related strata defined here informally as the Burns formation. This formation canExpand

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.

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
Impact origin of sediments at the Opportunity landing site on Mars
A simple alternative explanation involving deposition from a ground-hugging turbulent flow of rock fragments, salts, sulphides, brines and ice produced by meteorite impact is presented, which can account for all of the features observed without invoking shallow seas, lakes or near-surface aquifers.
