Sulfur has been detected by X‐ray spectroscopy in martian soils at the Viking, Pathfinder, Opportunity and Spirit landing sites. Sulfates have been identified by OMEGA and CRISM in Valles Marineris and by the spectrometers on the MER rovers at Meridiani and Gusev. The ubiquitous presence of sulfur has been interpreted as a widely distributed sulfate mineralogy. One goal of the Wet Chemistry Laboratory (WCL) on NASA's Phoenix Mars Lander was to determine soluble sulfate in the martian soil. We…

Sulfates hydrating bulk soil in the Martian low and middle latitudes
The evidence for sulfate‐bearing strata, across Late‐Noachian to Amazonian eons, suggests a central role for sulfates in acidity and salinity of Martian paleofluids and the planet's habitability.
Sulfate-bearing deposits at Dalangtan Playa and their implication for the formation and preservation of martian salts
Abstract The sulfate-bearing strata on Mars must have recorded rich information of its aqueous history. However, the hydrated sulfates observed in the surface thin layer by remote sensing, especially
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

Evidence for Calcium Carbonate at the Mars Phoenix Landing Site
TLDR
Results suggest that the soil at the Phoenix landing site must have suffered alteration through the action of liquid water in geologically the recent past, and an alkaline environment was revealed, in contrast to that found by the Mars Exploration Rovers, indicating that many different environments have existed on Mars.

Mineralogy at Meridiani Planum from the Mini-TES Experiment on the Opportunity Rover
TLDR
The Miniature Thermal Emission Spectrometer on Opportunity investigated the mineral abundances and compositions of outcrops, rocks, and soils at Meridiani Planum, finding Bounce rock is dominated by clinopyroxene and is close in inferred mineral composition to the basaltic martian meteorites.

TLDR
It is demonstrated that crystalline hematite deposits are associated with layered sulfates in other areas on Mars, implying that Meridiani-like ground water systems were indeed widespread and representative of an extensive acid sulfate aqueous system.
