Constraints on the formation of carbonates and low‐grade metamorphic phases in the Martian crust as a function of H2O‐CO2 fluids

Low‐grade metamorphic hydrous minerals and carbonates occur in various settings on Mars and in Martian meteorites. We present constraints on the stability of prehnite, zeolites, serpentine, and…

Spectral Properties of Anhydrous Carbonates and Nitrates

The spectral properties of anhydrous carbonates and nitrates are dominated by strong, sharp vibrational bands due to the CO32− and NO3− anions observed as absorption bands in near‐infrared spectra,…

The Case for Ancient Hot Springs in Gusev Crater, Mars

New and existing observations of the Home Plate region with observations from field and laboratory work demonstrate that a volcanic hydrothermal system manifesting both hot spring/geyser and fumarolic activity best explains the opaline silica rocks and proximal S-rich materials, respectively.

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.

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.
