  MARTIAN GEOCHEMICAL APPLICATIONS WITH FREZCHEM SUMMARY: NASA'S MISSION IS DRIVEN, IN PART, TO EXPLORE THE UNIVERSE AND SEARCH FOR LIFE. IN THIS PROPOSAL, WE WILL ADDRESS SCIENTIFIC QUESTIONS SUCH AS: CAN HYDROTHERMAL ENVIRONMENTS ACCOUNT FOR MASSIVE SILICA DEPOSITS AND OTHER ALTERATION MINERALOGIES ON MARS? HOW MIGHT HYDROTHERMAL SYSTEMS ON MARS DIFFER FROM THOSE ON EARTH, WHERE ON MARS IMPACT, VOLCANIC, AND OTHER GEO-HYDROTHERMAL SYSTEMS MAY INVOLVE LITTLE METEORIC WATER BUT ABUNDANT DISSOLVED SALTS, LESS GRANITE AND MORE MAFIC/ULTRAMAFIC ROCK, POSSIBLE ABUNDANT CONDENSED CO2 (LIQUID CO2, SOLID CO2, OR CLATHRATE HYDRATE CO2), AND MORE EXTREME TEMPERATURE GRADIENTS INTO CRYOGENIC CONDITIONS? CAN MASSIVE GYPSUM DEPOSITS IN THE NORTH POLAR REGION BE EXPLAINED BY A QUANTITATIVE GEOCHEMICAL MODEL THAT IS A FUNCTION OF TEMPERATURE, PRESSURE, AND CHEMICAL COMPOSITION? WHAT IS THE INFLUENCE OF SO2, H2S, SO3, AND SO4 CHEMISTRIES ON THE MARTIAN SURFACE ENVIRONMENT, CLIMATE, AND MINERALOGY? HOW IMPORTANT ARE ACIDIC IRON MINERALS LIKE JAROSITE, AND ALKALINE MINERALS LIKE ZEOLITES AND PHYLLOSILICATES IN CONTROLLING SURFACE ACIDITY ON MARS? WHAT ROLES DO TEMPERATURE, PRESSURE, AND CHEMICAL COMPOSITION PLAY IN CONTROLLING POTENTIAL HABITATS FOR LIFE ON MARS? RECENT MARS MISSIONS HAVE IMPLICATED HYDROTHERMAL SYSTEMS AND SULFUR CHEMISTRIES AS IMPORTANT GEOCHEMICAL DRIVERS ACROSS A WIDE RANGE OF MARTIAN SITES (E.G., ARABIA TERRA, GUSEV CRATER, JUVENTAE CHASMA, MERIDIANI PLANUM, AND VALLES MARINERIS). ALSO, ALKALINE SOILS (PH = 8-9) WERE FOUND AT THE PHOENIX LANDER SITE. FOR THE PAST DECADE, NASA HAS FUNDED THE DEVELOPMENT OF THE FREZCHEM MODEL. FREZCHEM IS PARAMETERIZED FOR BROAD RANGES OF TEMPERATURE (<-70 TO 25 C), PRESSURE (1-1000 BARS), AND CHEMICAL COMPOSITIONS [NA-K-MG-CA-FE(II)-FE(III)-AL-H-CL-BR-SO4-NO3-OH-HCO3-CO3-CO2-O2-CH4-SI- H2O] THAT INCLUDE 95 SOLID PHASES. HOWEVER, THE FREZCHEM MODEL CURRENTLY LACKS HIGH TEMPERATURE (>25 C), REDUCED-SULFUR CHEMISTRIES, AND SOME ALKALINE MINERAL CHEMISTRIES. IN THIS PROPOSAL, WE WILL (1) EXTEND THE VALIDITY OF FREZCHEM TO 95 C FOR HYDROTHERMAL SYSTEMS, (2) INTEGRATE SO2, H2S, AND SO3 CHEMISTRIES INTO FREZCHEM, AND APPLY THE MODEL FOR (3) HYDROTHERMAL ENVIRONMENTS, (4) STRONG ACID CHEMISTRIES, (5) MASSIVE SILICA DEPOSITIONS, (6) NORTH POLAR GYPSUM DEPOSITIONS, AND (7) ALKALINE MINERAL FORMATIONS ON MARS. THESE APPLICATIONS WILL ALSO EXAMINE THE PROSPOECTS FOR LIFE ON MARS. THESE APPLICATIONS WILL ALSO EXAMINE THE PROSPECTS FOR LIFE ON MARS CONSTRAINED BY A WIDE-RANGE OF CHEMICAL COMPOSITIONS AND TERMPERATURES. A GREAT DEAL OF SPECULATION IN PLANETARY GEOCHEMISTRY IS DUE TO A RELATIVE PAUCITY OF SOLID GEOCHEMICAL DATA FOR EXTRATERRESTRIAL BODIES. UNTIL EXTRATERRESTRIAL SAMPLES ARE ROUTINELY RETURNED TO EARTH, THIS LIMITATION WILL REMAIN. HEREIN LIES THE VALUE OF THEORETICAL MODELS SUCH AS FREZCHEM. THEORETICAL SIMULATIONS BASED ON SOUND CHEMICAL THERMODYNAMIC PRINCIPLES ENABLE US TO CONSTRAIN POTENTIAL MECHANISMS, TO SHARPEN OUR FOCUS ONTO MORE PROBABLE SCENARIOS, AND ULTIMATELY TO SHARPEN OUR UNDERSTANDING OF PLANETARY GEOCHEMISTRY.

  THE FREZCHEM MODEL IS AN EQUILIBRIUM CHEMICAL THERMODYNAMIC MODEL PARAMETERIZED FOR CONCENTRATED ELECTROLYTE SOLUTIONS USING THE PITZER APPROACH FOR THE TEMPERATURE RANGE FROM<-70 TO 25 C AND THE TOTAL PRESSURE RANGE FROM 1 TO 1000 BARS. THE MODEL IS CURRENTLY PARAMETERIZED FOR THE NA-K-MG-CA-FE(II)-FE(III)-AL-H-CL-CLO4-BR-SO4-NO3-OH-HCO3-CO3-CO2-O2-CH4-SI-H2O SYSTEM AND INCLUDES 101 SOLID PHASES INCLUDING ICE, 15 CHLORIDE MINERALS, SIX PERCHLORATE SALTS, 30 SULFATE MINERALS, 15 BICARBONATE/CARBONATE MINERALS, FIVE SOLID-PHASE ACIDS, THREE NITRATE MINERALS, SIX ACID-SALTS, TWO GAS HYDRATES, 13 IRON/ALUMINUM OXIDE/HYDROXIDES, THREE SILICON MINERALS, AND TWO BROMIDE SINKS. PHYSICOCHEMICAL PROPERTIES CALCULATED BY THE MODEL INCLUDE: ACTIVITY COEFFICIENTS AND ACTIVITIES OF SOLUTES AND WATER, OSMOTIC COEFFICIENT, IONIC STRENGTH, DENSITY OF AQUEOUS SOLUTIONS AND ICE, QUANTITY OF WATER, PH, EQUILIBRIUM WITH RESPECT TO SOLID PHASES AND ATMOSPHERIC GASES, TEMPERATURE AND PRESSURE DEPENDENCIES OF CHEMICAL REACTIONS, AND THE EUTECTIC TEMPERATURE OF AQUEOUS SOLUTIONS. ALL OF THESE PROPERTIES ARE IMPORTANT IN QUANTIFYING GEOCHEMICAL EQUILIBRIA. IN ADDITION, SOME PROPERTIES HAVE A DIRECT BEARING ON POTENTIAL LIMITING FACTORS FOR LIFE SUCH AS (1) THE ACTIVITY OF WATER AND THE OSMOTIC COEFFICIENT, WHICH ARE MEASURES OF SALINITY, (2) PH, WHICH IS A MEASURE OF ACIDITY, (3) THE PRESENCE OR ABSENCE OF WATER, (4) TEMPERATURE, AND (5) PRESSURE. THIS MODEL HAS BEEN WIDELY USED TO EXAMINE GEOCHEMICAL PROCESSES ON EARTH, MARS, AND EUROPA. THE MODEL IS UNIQUELY STRUCTURED BECAUSE IT CAN DEAL WITH MULTIPLE CHEMISTRIES AT SUBZERO TEMPERATURES, WHICH ARE HIGHLY RELEVANT FOR MARS. I HAVE MADE THE FORTRAN CODE FOR THIS MODEL FREELY AVAILABLE TO INTERESTED SCIENTISTS. NEVERTHELESS, THE CONTINUAL UPDATING, DISSEMINATION, AND ARCHIVING OF THE MODEL IS CHALLENGING. FURTHERMORE, EARLY VERSIONS OF THE MODEL HAD CONVERGENCE PROBLEMS. TO SOLVE THESE PROBLEMS, WE WERE NASA-MFR FUNDED TO (1) DEVELOP A MORE USER-FRIENDLY FORTRAN CODE, (2) IMPLEMENT AN INTERNET-ACCESSIBLE VERSION OF FREZCHEM, AND (3) DEVELOP AN ARCHIVE FOR VARIOUS MODEL VERSIONS. THIS PROJECT HAS BEEN COMPLETED (PERUSE TTP://FREZCHEM.DRI.EDU), EXCEPT FOR A PROBLEM WITH GAS HYDRATE CHEMISTRY. THE OBJECTIVES OF THIS NEW PROPOSAL ARE TO (1) UPDATE THE INTERNET VERSION FROM 56 TO 101 SOLID PHASES, WHICH WILL INVOLVE ADDING FE(III), AL, SI, CLO4, BR, AND GAS HYDRATE CHEMISTRIES, AND (2) UPDATE MODEL (FORTRAN CODE) ARCHIVES. THIS EFFORT WILL MAKE THE MODEL READILY AND EASILY AVAILABLE, EVEN TO CASUAL USERS, NOW AND IN THE FUTURE. AS A TOOL FOR MARTIAN APPLICATIONS, IT IS IMPORTANT TO KEEP BOTH FORTRAN CODES AND THE INTERNET MODEL UP TO DATE AND AVAILABLE FOR ALL WORLD-WIDE POTENTIAL USERS OF FREZCHEM. TODAY, SUCH A USER-FRIENDLY MODEL WOULD BE ESPECIALLY HELPFUL IN INTERPRETING THE EXCITING NEW DATA FROM THE MARS PHOENIX MISSION, WHERE PERCHLORATE/CARBONATE CHEMISTRIES ARE ESPECIALLY IMPORTANT.
