Geologic Mapping of Arsia and Pavonis Montes Mars Geologic Mapping of Arsia and Pavonis Montes, Mars We propose to investigate the volcanic, gradational, and tectonic processes that formed Arsia and Pavonis Montes using established geologic mapping techniques. We will use Mars Express HRSC data and CTX data that is geometrically rectified to MOLA data as a map base. These data will be supplemented by MOC, THEMIS, and (where available) HiRISE data. HRSC has complete coverage of Arsia and Pavonis Montes, enabling mapping across each shield at consistent and high spatial resolution. The objectives of this project include: 1) Determining the areal extent, distribution, and age relationships of different lava flow morphologies on the main flanks, rift aprons, and associated small-vent fields of Arsia and Pavonis Montes to identify and understand changes in effusive style across each volcano; 2) Determining the areal extent and distribution of purported glacial and aeolian deposits on the flanks of each shield and their relationship to the lava flows; 3) Characterizing erosional and tectonic features, such as rift zone graben, flank terraces, and channel networks, present on the flanks, rift aprons, and small-vent fields, to determine their relationships to volcanic materials and processes. The products of this research will be digital geologic maps of Arsia and Pavonis Montes, published in peer-reviewed journals, at a scale of 1:1,000,000. All of the required data are available in the PDS. The results of this research will be a more complete understanding of the processes that have formed and modified the Tharsis Montes, with an emphasis on understanding the late-stage effusive history, and the release and interaction with surface volatiles. These results will provide additional insight into understanding the overall evolution of the Tharsis Volcanic Province on Mars. This research is relevant to NASA Strategic Goal #3.3 to understand the genesis and evolution of Solar System bodies and physical processes active on the terrestrial planets.
