Workshop: Modeling Hydrous Environments on Mars

We would like to draw your attention at a workshop that will be held on June 1-3, 2009 at the Lunar and Planetary Institute, Houston, TX, USA.

Modeling Hydrous Environments on Mars

Forty years of investigations by many spacecraft have provided abundant evidence for the existence of water on Mars. Beyond well-known geomorphological evidence, recent orbiter and lander investigations have revealed chemical and data that point to past aqueous environments; and the number of detected aqueous-alteration related minerals is growing.

The variety of these minerals, and the potential processes which formed them, are broad. Oxides, hydroxides, salts, and phyllosilicates can be produced by processes ranging from evaporation and weathering to hydrothermal alteration caused by volcanic or impact events. These processes may have occurred under various conditions of water flow, water/rock ratios, pH, redox conditions, and temperature. Therefore, secondary minerals could provide insights on the processes that formed them at different times in Mars history.

To uncover those details, the Mars community has attacked the problem with a variety of techniques: numerical modeling, laboratory experiments, spacecraft observations, and analyses of Martian meteorites. Computer modeling has proven to be an invaluable tool in constraining the environmental conditions under which observed minerals and chemical patterns formed. To help integrate those different techniques, this workshop is aimed at bringing together Martian mineralogists, geochemists, and other interested scientists to discuss the mineralogical and chemical evidence for hydrous environments and the potential insights into their nature that numerical modeling, laboratory experiments, theory and spacecraft data analysis can provide. There will be a special focus on modeling techniques and any additional data is needed to improve them, because they are beginning to provide the interpretative framework for recent spacecraft observations.
