THE QUESTION OF THE BASIC VERTICAL AND HORIZONTAL COMPOSITIONAL STRUCTURE OF THE LUNAR CRUST IS STILL UNRESOLVED BUT CAN BE ADDRESSED WITH NEW REMOTE SENSING DATA. HIGH SPECTRAL RESOLUTION NEAR INFRARED AND MULTISPECTRAL THERMAL INFRARED LUNAR DATA ARE NOW BOTHAVAILABLE NEARLY GLOBALLY AND AT HIGH SPATIAL RESOLUTIONS. THIS PROPOSAL WILL UTILIZE THESE DATASETS AND INTEGRATE NEW LABORATORY EXPERIMENTS IN SIMULATED LUNAR ENVIRONMENT AND STATE OF THE ART RADIATIVE TRANSFER MODELS TO MAP THE MINERALOGY EXPOSED ON THE LUNAR SURFACE AND INFER ITS VERTICAL DISTRIBUTION.WE WILL ADDRESS THE FOLLOWING QUESTIONS: HOW DOES MG NUMBER VARY ACROSS THE LUNAR SURFACE? DOES THE LUNAR CRUST BECOME MORE MAFIC WITH DEPTH? IS LUNAR MANTLE EXPOSED ON THE SURFACE AND WHAT IS ITS MINERALOGY? THERE HAS BEEN SUCCESS DETECTING ANDMAPPING COMPOSITIONALLY EXTREME LITHOLOGIES SUCH AS PURE PLAGIOCLASE PYROXENE FREE OLIVINE OLIVINE FREE PYROXENE ILMENITE AND MGSPINEL USING NEAR INFRARED SPECTROSCOPY AND SILICA RICH LITHOLOGIES AND VARIATIONS IN PLAGIOCLASE COMPOSITION USING THERMAL INFRARED MULTISPECTRAL IMAGING. WHILE THESE ARE IMPORTANT ADVANCES OTHER IMPORTANT LUNAR SCIENCE PROBLEMS REQUIRE DETERMINING THE RELATIVEABUNDANCES OF THE MAJOR MINERALS WHERE THE LITHOLOGIES ARE NOT DOMINATED BY A SINGLE MINERAL AND TO WHICH A PARTICULAR SPECTROSCOPIC TECHNIQUE IS PARTICULARLY SENSITIVE. FORTUNATELY THE STRENGTHS OF NEAR INFRARED SPECTROSCOPY NAMELY DIFFERENTIATING AMONG MAGIC MINERALS AND THERMAL INFRARED MULTISPECTRAL OBSERVATIONS ASSESSING FELDSPAR MAFIC RATIOS ARE COMPLEMENTARY AND TOGETHER CANPROVIDE A CLOSED ACCURATE SOLUTION. THE PROPOSED WORK WILL ACCOMPLISH THE FOLLOWING: REFINE AND VALIDATE A MINERAL ABUNDANCE ESTIMATE METHODOLOGY CAPABLE OF BETTERTHAN 10 PERCENT ABSOLUTE ACCURACY THAT INTEGRATES NIR AND TIR SPECTRAL IMAGING USING RADIATIVE TRANSFER MODELING AND TARGETED LABORATORY TIR MEASUREMENTS OF LUNAR SOILS AND ANALOG MINERALS IN SIMULATED LUNAR ENVIRONMENT DERIVE THE GLOBAL MINERALOGY OF THE MOON AIMED AT MAPPING AND UNDERSTANDING VARIATIONS IN MG NUMBER ASSESS THE STRUCTURE OF THE LUNAR CRUST BY EXAMINING CRATER CENTRALPEAKS THROUGH IMPROVED UNDERSTANDING OF THE FELDSPAR MAFIC RATIO AND MAFIC MINERALOGY PROVIDED BY OUR METHOD INVESTIGATE MAFIC COMPOSITIONAL ANOMALIES THAT COINCIDE WITH LOW PLAGIOCLASE ABUNDANCES AS POTENTIAL EXPOSURES OF LUNAR MANTLE MAKE PUBLICLY AVAILABLE ALL HIGH RESOLUTION MINERAL ABUNDANCE MAP PRODUCTS AND MEASURED LABORATORY SPECTRA. THE PRODUCTS OF THESE COMBINED ANALYSES WILL BE OF GREAT VALUE TO THE LUNAR COMMUNITY AND LAY THE GROUNDWORK FOR FURTHER UNDERSTANDING LUNAR SURFACE COMPOSITIONAND THUS THIS FORMATION AND EVOLUTION OF THE LUNAR CRUST.THE PROPOSED WORK IS RELEVANT TO THE LDAP PROGRAM BECAUSE IT USES PUBLICALLY AVAILABLE DATA FROM THE LRO DIVINER CHANDRYANN 1 M3 AND KAGUYA MI MISSIONS. SPECIFICALLY IT DIRECTLY ADDRESSES THE HIGH PRIORITY AREAS OF LUNAR RESEARCH IDENTIFICATION CHARACTERIZATION OF LUNAR MINERALOGY AS A FUNCTION OF LOCATION AND DEPTH AND CONTRIBUTES TO OTHERS INCLUDING IDENTIFICATION AND/ORCHARACTERIZATION OF POTENTIAL LANDING SITES OF HIGH LUNAR SCIENCE RETURN. BECAUSE THIS PROPOSAL IS RELEVANT TO LDAP IT IS INTRINSICALLY RELEVANT TO NASA PSD.
