  author={P. Christensen and S. Ruff},
  journal={Journal of Geophysical Research},
[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, precipitation from circulating fluids of hydrothermal origin, or the thermal oxidation of magnetite-rich ash. Analysis of Odyssey Thermal Emission Imaging System (THEMIS) infrared and visible images, together with MGS TES, MOLA, and MOC data, has provided additional insight into the Meridiani region.

Spectral properties of Lake Superior banded iron formation: application to Martian hematite deposits.
Lake Superior Type banded iron formation was investigated as a spectral and possible process analog to Mars, and will provide useful data for determining whether BIFs exist elsewhere on Mars and are, thus, relevant to current and future Mars exploration missions. Expand
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

Paleolakes and impact basins in southern Arabia Terra, including Meridiani Planum: Implications for the formation of hematite deposits on Mars
[1] The hematite deposit in Meridiani Planum was selected for a Mars Exploration Rover (MER) landing site because water could be involved in the formation of hematite, and water is a key ingredientExpand
Global mapping of Martian hematite mineral deposits: Remnants of water‐driven processes on early Mars
