5 ANALYSES OF GROOVED TERRAIN DEVELOPMENT AND TECTONIC RESURFACING ON ICY MOONS RECENT ADVANCES IN FINITE ELEMENT MODELING OF GROOVED TERRAIN ON GANYMEDE HAVE REIGNITED THE DEBATE OVER HOW THESE TECTONIC LANDFORMS DEVELOP AND EVOLVE, AND WHETHER TECTONIC RESURFACING IS A VIABLE GEOLOGIC PROCESS AT WORK ON ICY MOONS. THIS PROJECT SEEKS TO CHARACTERIZE, THROUGH A SUITE OF PHYSICAL ANALOG MODELING EXPERIMENTS, (I) HOW ICY LITHOSPHERES RESPOND TO LOCALIZED EXTENSION, SPECIFICALLY THE THREE-DIMENSIONAL DEVELOPMENT OF PINCH-AND-SWELL TOPOGRAPHY, AS WELL AS (II) TEST THE EFFICACY OF TECTONIC PROCESSES TO RESURFACE A MOON S SURFACE (E.G., DESTROY CRATERS, BRIGHTEN TERRAIN). PROJECT MODEL RESULTS WILL BE COMPARED TO FINITE ELEMENT MODELS TO HELP INFORM AND CROSS-CALIBRATE THESE DIFFERENT MODELING APPROACHES.
