Ancient Carbonate Minerals on Mars The historical presence of liquid water on Mars together with a CO 2-rich atmosphere should have resulted in the accumulation of large deposits of carbonate minerals. Yet, evidence for the presence of carbonates on the surface of Mars has been scarce. Using data collected by the Mars Exploration Rover, Spirit, Morris et al. (p. 421, published online 3 June; see the Perspective by Harvey) now present evidence for carbonate-rich outcrops in the Comanche outcrops… 

Geochemistry of Carbonates on Mars: Implications for Climate History and Nature of Aqueous Environments

Ongoing research on martian meteorites and a new set of observations of carbonate minerals provided by an unprecedented series of robotic missions to Mars in the past 15 years help define new

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

Carbonates on Mars

Aqueous environmental history of Mars revealed by mineralogy and geochemistry of outcrop exposures of sedimentary rocks

Recent high-resolution spectral images and in-situ observations have revealed more than 1000 outcrops of diverse aqueous mineral deposits on Mars. Layered deposits of phyllosilicates (and carbonates)

Carbonates and Martian Climate

Morris et al. (3) report the detection of ample carbonates dispersed within the subsurface, thereby strengthening arguments that CO2 played a major role in the early martian climate system.

Carbonates in the Martian meteorite Allan Hills 84001 formed at 18 ± 4 °C in a near-surface aqueous environment

The precipitation temperature of secondary carbonate minerals preserved in the oldest known sample of Mars’ crust is determined, finding that the carbonates in ALH84001 precipitated at a temperature of approximately 18 °C, with water and carbon dioxide derived from the ancient Martian atmosphere.

A Comparative Analysis of Evaporate Sediments on Earth and Mars: Implications for the Climate Change on Mars

The knowledge of Martian salts has gone through substantial changes during the past decades. In the 70th of last century, Viking landers have noticed the existence of salts on Mars. Several salt

Detection of Carbonates in Martian Weathering Profiles

Noachian surfaces on Mars exhibit vertical assemblages of weathering horizons termed as weathering profiles; this indicates that surface water caused alteration of the rocks that required a

Orbital evidence for more widespread carbonate‐bearing rocks on Mars

Carbonates are key minerals for understanding ancient Martian environments because they are indicators of potentially habitable, neutral‐to‐alkaline water and may be an important reservoir for

Evidence for a Noachian-Aged Ephemeral Lake in Gusev Crater, Mars

Gusev crater has long been considered the site of a lake early in Martian history, but the Mars Exploration Rover Spirit found no apparent evidence of lake deposits along its 7 km traverse from 2004



Orbital Identification of Carbonate-Bearing Rocks on Mars

The presence of carbonate as well as accompanying clays suggests that waters were neutral to alkaline at the time of its formation and that acidic weathering, proposed to be characteristic of Hesperian Mars, did not destroy these carbonates and thus did not dominate all aqueous environments.

Alteration Assemblages in Martian Meteorites: Implications for Near-Surface Processes

The SNC (Shergotty-Nakhla-Chassigny) meteorites have recorded interactions between martian crustal fluids and the parent igneous rocks. The resultant secondary minerals — which comprise up to ∼1

A chemical model for evaporites on early Mars: Possible sedimentary tracers of the early climate and implications for exploration

Martian geomorphology seems to indicate extensive hydrological activity during the Noachian era. Liquid water at the surface would require a large greenhouse effect that is widely hypothesized to

A possible high-temperature origin for the carbonates in the martian meteorite ALH84001

It is argued that the most likely explanation for the observed compositions, and for the absence of co-existing hydrous minerals, is that the carbonates were formed by reactions between hot (>650 °C), CO2-rich fluids and the ultramafic host rock during an impact event.

Detection of Silica-Rich Deposits on Mars

Opaline silica deposits found on Mars are interpreted to have formed under hydrothermal conditions and therefore to be strong indicators of a former aqueous environment, important for understanding the past habitability of Mars.

Hydrothermal processes at Gusev Crater: An evaluation of Paso Robles class soils

[1] The Mars Exploration Rover Spirit analyzed multiple occurrences of sulfur-rich, light-toned soils along its traverse within Gusev Crater. These hydrated deposits are not readily apparent in

The age of the carbonates in martian meteorite ALH84001.

The carbonate formation age is contemporaneous with a period in martian history when the surface is thought to have had flowing water, but also was undergoing heavy bombardment by meteorites, therefore, this age does not distinguish between aqueous and impact origins for the carbonates.

Evidence for Calcium Carbonate at the Mars Phoenix Landing Site

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.

Iron mineralogy and aqueous alteration from Husband Hill through Home Plate at Gusev Crater, Mars: Results from the Mössbauer instrument on the Spirit Mars Exploration Rover

[1] Spirit's Mossbauer (MB) instrument determined the Fe mineralogy and oxidation state of 71 rocks and 43 soils during its exploration of the Gusev plains and the Columbia Hills (West Spur, Husband
