THE FOCUS OF THE WORK PROPOSED HERE IS TO IDENTIFY AND CHARACTERIZE THE COMPOSITION OF THE LUNAR CRUST IN A MANNER THAT ALLOWS LOCAL AND GLOBAL COMPOSITIONAL PROPERTIES DETECTED AT HIGH SPATIAL RESOLUTION TO CONSTRAIN PROCESSES AND PRODUCTS OF EARLY CRUSTAL EVOLUTION. THE COMPOSITION OF THE DEEP LUNAR CRUST IS EVALUATED THROUGH ANALYSIS OF THE MINERALOGY OF MATERIALS EXPOSED BY BASINS AND LARGE SUPERIMPOSED CRATERS. LOCAL COMPOSITIONAL VARIATIONS ARE EXAMINED IN DETAIL TO IDENTIFY THE PHASES THAT OCCUR TOGETHER DURING CRUSTAL FORMATION. LATERAL VARIATIONS ARE EXAMINED TO EVALUATE HETEROGENEITY OF CRUSTAL PROCESSES. VERTICAL COMPOSITIONAL STRATIGRAPHY OF THE EARLY CRUST IS ASSESSED FROM SYSTEMATIC PATTERNS OBSERVED OVER LARGE REGIONS AND/OR GLOBALLY. BASINS INCLUDED IN THE FIRST PHASE INCLUDE ORIENTALE MOSCOVIENSE AND SOUTH POLE-AITKEN THESE WILL LATER BE EXPANDED TO INCLUDE SEVERAL OTHERS SUCH AS SCHR DINGER CRISIUM APOLLO AND SMYTHII. THESE ARE ALL BASINS THAT APPEAR TO HAVE EXCAVATED DEEPLY INTO THE LUNAR CRUST BASED ON EXISTING GEOPHYSICAL DATA. PRIMARY COMPOSITIONAL ANALYSES WILL BE BASED ON M3 GLOBAL DATA BECAUSE IT PROVIDES COMPOSITIONAL INFORMATION AT THE HIGHEST SPATIAL RESOLUTION (~140 M/PIXEL). THESE WILL BE INTEGRATED WITH DATA FROM LUNAR PROSPECTOR KAGUYA AND LRO. DATA ANALYSIS ACTIVITIES BUILD ON SUCCESSFUL EXPERIENCE WORKING WITH M3 DATA. REFLECTANCE DATA WILL BE PREPARED FROM M3 INDIVIDUAL DATA SWATHS AND RELEVANT MOSAICS WILL BE GENERATED. ANALYSIS TOOLS EMPHASIZE QUANTITATIVE IDENTIFICATION OF DIAGNOSTIC MINERAL ABSORPTIONS AND WILL INCLUDE ASSESSMENT OF SUCH PROPERTIES AS INTEGRATED BAND DEPTH FOR 1 AND 2?M FERROUS ABSORPTIONS BAND CENTER BAND WIDTH NEAR-INFRARED CONTINUUM SLOPE BAND STRENGTH (RELATIVE TO CONTINUUM) FOR SPECIFIC DIAGNOSTIC WAVELENGTHS. WHERE THE DATA ARE OF SUFFICIENT QUALITY MORE ADVANCED TOOLS (E.G. MGM) WILL ALSO BE USED TO EVALUATE COMPOSITION. KEY ASPECTS OF THESE ANALYSES INCLUDE: IDENTIFYING THE MINERALS PRESENT IDENTIFYING THE SPATIAL SCALE OF SPECIFIC LITHOLOGIES AND MAPPING THEIR EXTENT CHARACTERIZING THE COMPOSITION OF KEY MINERALS (E.G. MG#) IDENTIFYING LITHOLOGIES THAT OCCUR TOGETHER OR NEARBY ASSESS THE REGIONAL OCCURRENCE AND RELATION TO THE ASSOCIATED IMPACT EVENT (BASIN) COMPARE REGIONAL AND GLOBAL COMPOSITIONAL RESULTS. THESE ANALYSES WILL PROVIDE DIRECT INFORMATION ABOUT THE COMPOSITION OF THE LOWER CRUST. THIS WILL SUBSTANTIALLY CONSTRAIN THE COMPOSITIONAL STRATIGRAPHY OF THE LUNAR CRUST AND MODELS OF EARLY CRUSTAL EVOLUTION.
