47th Lunar and Planetary Science Conference (2016) sess405.pdf Wednesday, March 23, 2016 [W405] MARS GEOMORPHOLOGY: FLUVIOLACUSTRINE ACTIVITY TO GLOBAL CLIMATE IMPLICATIONS 8:30 a.m. Waterway Ballroom 6 Chairs: John Grant Devon Burr 8:30 a.m. Kite E. S. * Armstrong J. C. Goldblatt C. Gao P. Mayer D. P. Cadence and Cause of Lake-Forming Climates on Mars [#1312] Rare shifts in Mars’ mean obliquity can trigger short-lived lake-forming climates, resolving the tension between lake hydrology and olivine persistence. 8:45 a.m. Grant J. A. * Wilson S. A. The Nature and Extent of Aqueous Deposits Related to the Hale Impact Crater on Mars [#2530] Aqueous flows related to formation of Hale crater extend considerably further than previously recognized and highlight the widespread effects of the impact. 9:00 a.m. Horvath D. G. * Andrews-Hanna J. C. The Influence of Climate and Permeability on the Formation and Geologic Stability of the Gale Crater Lake [#2474] The influence of permeability and climate on the stability and formation of a Gale Crater lake on Mars are investigated using a hydrological model. 9:15 a.m. Goudge T. A. * Milliken R. E. Head J. W. Mustard J. F. Fassett C. I. Sedimentology of the Jezero Crater Western Fan Deposit: 1. Evidence for a Deltaic Origin and Implications for Future Exploration [#1122] The stratigraphic architecture and mineralogy of the Jezero western fan deposit indicate it is a delta, and is highly compelling for future in situ exploration. 9:30 a.m. Davis J. M. * Balme M. Grindrod P. M. Williams R. M. E. Gupta S. Inverted Channels in Arabia Terra, Mars: Remnants of an Ancient Drainage Network [#1982] CTX-scale mapping project of inverted fluvial channels throughout Arabia Terra, Mars, which may bridge the gap between the equator and the northern lowlands. 9:45 a.m. Adeli S. * Hauber E. Kleinhans M. Le Deit L. Platz T. et al. Well-Preserved Amazonian-Aged Fluvial System in the Terra Cimmeria Region, Mars [#2211] We are reporting here the presence of a complex fluvial system of Amazonian age, located in the southern mid-latitude regions of Mars. 10:00 a.m. Burr D. M. * Jacobsen R. E. Lefort A. Thermal Detection of an Extensive Buried Fluvial Unit in the Aeolis Dorsa Region, Medusae Fossae Formation, Mars [#1392] Thermal data indicate that the numerous surficial inverted fluvial deposits in the Aeolis Dorsa are underlain by a more extensive near-surface fluvial unit. 10:15 a.m. Buhler P. B. * Fassett C. I. Head J. W. III Lamb M. P. Timescales of Fluvial Activity and Intermittency in Milna Crater, Mars [#2587] The time to construct the lacustrine sediment fill in Milna is compared to regional hydrology timescales to obtain transport intermittency (0.01–0.1%). 47th Lunar and Planetary Science Conference (2016) sess405.pdf 10:30 a.m. Rogers A. D. * Head J. W. Understanding Late Noachian Surface Environments on Mars Through Analyses of Basin-Filling Bedrock Units [#1924] Geologic observations of Noachian units in Terra Cimmeria are presented and discussed in the context of different climate scenarios for early Mars. 10:45 a.m. Irwin R. P. III * Noachian Geomorphic Surfaces and Implications for the Paleoclimate of Mars [#3015] Intercrater geomorphic surfaces on Mars indicate a Noachian paleoclimate that was more arid than around the Noachian/Hesperian boundary. 11:00 a.m. Fastook J. L. * Head J. W. Late Noachian Icy Highlands Ice Flow Synthesis [#1161] Using an ice sheet model we evaluate features of Late Noachian ice sheets that can leave a lasting impact on the landscape after the ice sheets are removed. 11:15 a.m. Parker T. J. * Anderson R. C. Mars Was Warm and Wet, But Not for Long? Twelve Years of Field Geomorphology at Meridiani Planum [#2689] Several distinct morphologies visited by Opportunity suggest a short-lived transgressive marine environment that was likely a direct result of the LHB. 11:30 a.m. Clifford S. M. * McCubbin F. How Well Does the Present Surface Inventory of Water on Mars Constrain the Past? [#2388] The present near-surface inventory of ice places no constraint on either the past near-surface inventory of H2O or the former presence of a northern ocean. .
