INTRODUCTION: THE UPPER SURFACE OF MARS IS PREDOMINANTLY BASALTIC IN COMPOSITION WITH LARGE VOLCANIC CONSTRUCTS THAT OCCUR OVER PRESUMABLY STABLE MANTLE HOTSPOTS OR LONG-LIVED VOLCANIC CENTERS. AQUEOUS ALTERATION OF THESE BASALTIC PRECURSORS HAS BEEN PERVASIVE IN THE OLDEST (NOACHIAN) TERRAINS AND LINKED TO WEATHERING HYDROTHERMAL AND DIAGENETIC ALTERATION. CLAY MINERALS (PHYLLOSILICATES) ARE FOUND THOUGH THEIR PROVENANCE IS NOT WELL KNOWN AND CAN INCLUDE FORMATION IN GROUNDWATER AQUIFERS IN HYDROTHERMAL SYSTEMS THAT ARE FOUND AROUND IMPACT CRATERS OVER INTRUSIVE MAGMATIC CENTERS OR DURING COOLING OF THE EARLY MARTIAN CRUST. RECENTLY TWO CONTINUOUSLY-CORED BOREHOLES WERE MADE INTO THE INTERIOR OF THE ISLAND OF HAWAII. WE COLLECTED 780 SPECTRA USING A FIELD PORTABLE SPECTROMETER TO CHARACTERIZE ALTERATION PHASES IN THE LOWER HALF OF THE FIRST HOLE. THE DATA SHOW BOTH NOTABLE CHANGES IN THE PRIMARY MAFIC MINERALOGY AND ALTERATION SUITES THAT INCLUDE A VARIETY OF MG-FE CLAY MINERALS AND ZEOLITES ALL PHASES THAT HAVE BEEN IDENTIFIED AS CRUSTAL ALTERATION PRODUCTS ON MARS. ADDITIONALLY 25 CUT SECTIONS WERE TAKEN TO EXPLORE THE ALTERATION MINERALOGY IN MORE DETAIL INCLUDING IMAGING SPECTROSCOPY USING A PLANETARY PROTOTYPE INSTRUMENT AT JPL. KEY OBJECTIVES: THE MAIN GOALS OF THE PROPOSED WORK ARE TO EXPAND ON THIS PRELIMINARY STUDY WITH A DETAILED EXAMINATION OF THE MINERALOGY OF BOTH CORE HOLES USING BOTH POINT SPECTROSCOPY AND MODERN CORE SPECTRAL IMAGING TOOLS COUPLED WITH GEOCHEMICAL MODELING. IN PARTICULAR EVOLUTION OF THE MODAL MINERALOGY OF MAFIC SUITES WAS NOT A TARGET OF THE 2014 DATA COLLECT BUT OBSERVED SPECTRAL DIFFERENCES CAN POTENTIALLY BE LINKED DIFFERENCES IN ALTERATION PRODUCTS. BASED ON A COMPREHENSIVE EXAMINATION OF BOTH PRIMARY AND ALTERATION MINERALOGY WITH DEPTH SELECTED SAMPLES WILL BE EXAMINED AT HIGHER RESOLUTION USING ADDITIONAL TECHNIQUES TO CONSTRAIN THE ALTERATION HISTORY DURATION TIMING AND TEMPERATURE OF ALTERATION EVENTS AND WHETHER THEY ARE SUB-AERIAL OR SUB-SURFACE WATER-ROCK INTERACTIONS. THE STUDY IS EXPECTED TO PROVIDE CONSTRAINTS ON THE PROVENANCE OF MARTIAN CRUSTAL CLAYS AND ILLUMINATE POTENTIAL ALTERATION PATHWAYS AND THE NATURE OF EARLY MARTIAN ENVIRONMENTS. METHODS/TECHNIQUES: WE WILL COLLECT BOTH POINT AND IMAGING SPECTROMETER DATA FOR THE FULL LENGTH OF BOTH CORE HOLES ~ 3290M. DATA WILL BE ACQUIRED FOR BOTH THE VNIR/SWIR (0.4 TO 2.5 UM) AND LWIR (2-15 UM) SPECTRAL RANGES ALLOWING COMPARISON OF DATA WITH INFORMATION FROM OMEGA CRISM AND TES. DATA WILL BE ANALYZED USING A COMBINATION OF STANDARD ENVI PROCESSING ROUTINES BAND COMBINATIONS AND RATIOS TO HIGHLIGHT DISTINCT MINERAL COMPOSITIONS AND CUSTOM CODE FOR LINEAR AND INTIMATE SPECTRAL MIXTURE MODELING. SELECTED SECTIONS OF CORE WILL BE CUT AND PROCESSED USING HIGH-RESOLUTION TECHNIQUES INCLUDING ELECTRON MICROPROBE AND SEM XRD AND XRF. DETAILED MINERALOGY WILL BE MODELED TO DERIVE FLUID-ROCK RATIOS AND ALTERATION TEMPERATURES USING TOUGHREACT OR THE GEOCHEMISTS WORKBENCH. PERCEIVED IMPACT AND RELEVANCE TO SSW: THE PROPOSED EFFORT ADDRESSES TOPICS WITHIN THE "SURFACES AND INTERIORS" COMPONENT OF SSW INCLUDING VOLCANISM EVOLUTION AND MODIFICATION OF SURFACES AND FLUID INVENTORIES THAT LEAD TO OBSERVED SURFACE GEOCHEMISTRY. THE DATA FROM THE HAWAII ANALOG SITE WILL BE LINKED TO EXISTING RESULTS FROM BOTH ORBITAL AND LANDED MISSIONS AT MARS. CONCURRENT PME REQUEST: WE PLAN TO SUBMIT A CONCURRENT PLANETARY MAJOR EQUIPMENT REQUEST FOR THE PURCHASE OF A NEW VNIR/ SWIR PORTABLE FIELD SPECTROMETER $73 300 FOR UNR. THE EXISTING UNIT WAS ACQUIRED IN 2005 AND IS FAILING DUE TO AGE. THE EQUIPMENT WILL BE USED TO COLLECT NEW DATA FOR THIS PROJECT.
