THE PROPOSED INVESTIGATION WILL PROVIDE NEW CONSTRAINTS ON THE GEOLOGIC EVOLUTION OF THE LARGEST VOLCANIC PROVINCE ON THE MARTIANSURFACE THROUGH DETAILED MAPPING OF ITS SOUTHERN EXTENT IN DAEDALIA PLANUM. THE STYLES TIMING AND SPATIAL EXTENT OF THARSIS VOLCANISMWILL BE EXAMINED THROUGH A SYSTEMATIC MAPPING INVESTIGATION OF THE LAVA FLOW FIELDS TO THE SOUTH OF ARSIA MONS THAT FORM DAEDALIAPLANUM AND EMBAY THE HIGHLANDS OF TERRA SIRENUM TO THE SOUTH. THIS RESEARCH WILL INCLUDE PRODUCTION OF:A) ONE FORMAL USGS GEOLOGIC MAP PUBLICATION A 1:1M-SCALE GEOLOGIC MAP OF SIX MTM QUADRANGLES (-30137 -30132 -30127 -35137 -35132 AND -35127) IN DAEDALIA PLANUM COVERING THE FRESH CRATER ZUMBA AND ITS EXTENSIVE RAYS THE SURROUNDING LAVA FLOW FIELDS SMOOTH AND RIDGED PLAINS AND THE HIGHLANDS OF TERRA SIRENUM TO THE SOUTH ANDB) AS A DIGITAL SUPPLEMENT TO THE GEOLOGIC MAP A DETAILED LAVA FLOW FIELD MAP PROVIDING REPRESENTATIONS OF FLOW LOBE MARGINS CHARACTERIZATION OF DIFFERENT FLOW TYPES DELINEATION OF CHANNEL AND LEVEE SYSTEMS AND FLOW SURFACE TEXTURES AND STRUCTURES AS WELL ASDOCUMENTATION OF RELATIVE AGE RELATIONSHIPS BETWEEN ADJACENT FLOWS. FLOW FIELD MAPPING WILL BE COMPILED AT 1:100 000 SCALE.GEOLOGIC MAPPING WILL BE BASED PRIMARILY ON THEMIS DAYTIME THERMAL INFRARED (TIR) IMAGES SUPPORTED BY VARIOUS OTHER IMAGINGDATASETS AND THE DETAILED LAVA FLOW FIELD MAPS WILL BE GENERATED USING CTX AND THEMIS VIS COVERAGE. THIS PROJECT WILL UTILIZEGEOGRAPHIC INFORMATION SYSTEMS (GIS) SOFTWARE AND ANALYSIS TOOLS FOR THE PRODUCTION OF BOTH HARD COPY AND DIGITAL MAP PRODUCTS.
