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.

Evidence for Water at Meridiani

The Mars Exploration Rover Opportunity has examined sedimentary structures in the Burns formation at Meridiani Planum. The materials in this formation reflect, in part, subaqueous deposition of



Dissolution-collapse breccias and paleokarst resulting from dissolution of evaporite rocks, especially sulfates

The lithological trinity of dolostone, limestone, and sulfates (anhydrite and/or gypsum) is subject to rapid dissolution of the sulfates and leads to the development of dissolution-collapse breccias

Geologic setting and origin of Terra Meridiani hematite deposit on Mars

[1] We have completed a regional analysis of the hematite deposit in Terra Meridiani and conclude that the unit is in the midst of a 600-m-thick stack of friable layered materials superposed on

ABSTRACT This study attempts to ascertain whether the differing provenance sources and plate tectonic settings of deposition of clastic sediments and rocks can be identified by chemical means, thus

Formation of the hematite-bearing unit in Meridiani Planum: Evidence for deposition in standing water

[1] The most plausible models for the origin and evolution of a unique geologic unit in Meridiani Planum, Mars, are low-temperature precipitation of Fe oxides/oxyhydroxides from standing water,

Deposition and early alteration of evaporites

The depositional settings for primary and early diagenetic evaporite deposits generally fall into three categories: marginal (mixed shallow‐subaqueous and subaerial), shallow and deep subaqueous.

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.

Diagenetically Enhanced Bedding in Argillaceous Platform Limestones: Stratified Cementation and Selective Compaction

A field and petrographic study has been made of 34 massive beds in argillaceous limestones of open marine platform facies in the U.K. Lithologies include grainstones, packstones, wackestones and lime
