Abstract STUBBLEFIELD, RASHONDA KIAM. Extensional Tectonics at Alba Mons, Mars
Abstract STUBBLEFIELD, RASHONDA KIAM. Extensional Tectonics at Alba Mons, Mars: A Case Study for Local versus Regional Stress Fields. (Under the direction of Dr. Paul K. Byrne). Alba Mons is a large shield volcano on Mars, the development of which appears to be responsible for tectonic landforms oriented radially and circumferentially to the shield. These landforms include those interpreted as extensional structures, such as normal faults and systems of graben. These structures, however, may also be associated with broader, regional stress field emanating from the volcano-tectonic Tharsis Rise, to the south of Alba Mons and centered on the equator. In this study, I report on structural and statistical analyses for normal faults proximal to Alba Mons (in a region spanning 95–120° W and 14–50° N) and test for systematic changes in fault properties with distance from the volcano and from Tharsis. A total of 11,767 faults were mapped for this study, and these faults were all measured for strike, length, and distance from Alba Mons and Tharsis. Additional properties were qualitatively and quantitatively analyzed within a subset of 62 faults, and model ages were obtained for two areas with crater statistics. Distinguishing traits for each structure population include fault properties such as strike, vertical displacement (i.e., throw) distribution profiles, displacement–length (Dmax/L) scaling, and spatial (i.e., cross-cutting) relationships with adjacent faults with different strikes. The only statistically significant correlation in these analyses was between study fault strike with distance from Tharsis. The lack of trends in the data suggest that one or more geological processes is obscuring the expected similarities in properties for these fault systems, such as volcanic resurfacing, mechanical restriction, or fault linkage. -

FROM WET PLANET to RED PLANET Current and Future Exploration Is Shaping Our Understanding of How the Climate of Mars Changed
FROM WET PLANET TO RED PLANET Current and future exploration is shaping our understanding of how the climate of Mars changed. Joel Davis deciphers the planet’s ancient, drying climate 14 DECEMBER 2020 | WWW.GEOLSOC.ORG.UK/GEOSCIENTIST WWW.GEOLSOC.ORG.UK/GEOSCIENTIST | DECEMBER 2020 | 15 FEATURE GEOSCIENTIST t has been an exciting year for Mars exploration. 2020 saw three spacecraft launches to the Red Planet, each by diff erent space agencies—NASA, the Chinese INational Space Administration, and the United Arab Emirates (UAE) Space Agency. NASA’s latest rover, Perseverance, is the fi rst step in a decade-long campaign for the eventual return of samples from Mars, which has the potential to truly transform our understanding of the still scientifi cally elusive Red Planet. On this side of the Atlantic, UK, European and Russian scientists are also getting ready for the launch of the European Space Agency (ESA) and Roscosmos Rosalind Franklin rover mission in 2022. The last 20 years have been a golden era for Mars exploration, with ever increasing amounts of data being returned from a variety of landed and orbital spacecraft. Such data help planetary geologists like me to unravel the complicated yet fascinating history of our celestial neighbour. As planetary geologists, we can apply our understanding of Earth to decipher the geological history of Mars, which is key to guiding future exploration. But why is planetary exploration so focused on Mars in particular? Until recently, the mantra of Mars exploration has been to follow the water, which has played an important role in shaping the surface of Mars. -
The Formation History of Olympus Mons from Paleo-Topography
42nd Lunar and Planetary Science Conference (2011) 2202.pdf THE FORMATION HISTORY OF OLYMPUS MONS FROM PALEO-TOPOGRAPHY. L. M. Jozwiak1,2 R. J. Isherwood2, and J. C. Andrews-Hanna2, 1Dept. of Earth, Atmospheric, and Planetary Sciences, MIT, Cambridge, MA, [email protected], 2Dept. of Geophysics, Colorado School of Mines, Golden, CO, [email protected]. Introduction: The Olympus Mons shield volcano on the northwestern edge of Mars’ Tharsis rise is the largest volcano in the solar system. Its volcanic his- tory is intimately tied with the volcanic and geody- namic history of Tharsis and of Mars as a whole. Pre- vious studies used crater counting to estimate the age of the flanks of Olympus, with typical values of ~200 Myr [1]. However, establishing the formation history for Olympus Mons is complicated by the fact that each volcanic eruption resurfaces the flanks, erasing the previous crater record. Here we place constraints on the bulk formation history of Olympus Mons by recon- structing the paleo-flexural history of the surrounding region. Crater retention ages from lava flows on the flexural trough surrounding the edifice that pre-date the trough are used to constrain the onset of volcanic loading. Crater retention ages from the aureole depos- its are used to constrain the age at which a significant fraction of the edifice was in place. These two ages bracket the main constructional period of Olympus. Paleo-topography of the Olympus Mons flexural trough. The concept of paleo-topography is used in terrestrial geodynamics to reconstruct the vertical mo- tions of the lithosphere [2], but has seen less use in planetary applications [3]. -

Persistent Or Repeated Surface Habitability on Mars During the Late Hesperian - Amazonian
Persistent or repeated surface habitability on Mars during the Late Hesperian - Amazonian Edwin S. Kite1,*, Jonathan Sneed1, David P. Mayer1, Sharon A. Wilson2 1. University of Chicago, Chicago, Illinois, USA (* [email protected]) 2. Smithsonian Institution, Washington, District of Columbia, USA Published in: Geophys. Res. Lett., 44, doi:10.1002/2017GL072660. Key Points: • Alluvial fans on Mars did not form during a short-lived climate anomaly • We use the distribution of observed craters embedded in alluvial fans to place a lower limit on fan formation time of >20 Ma • The lower limit on fan formation time increases to >(100-300) Ma when model estimates of craters completely buried in the fans are included Abstract. Large alluvial fan deposits on Mars record relatively recent habitable surface conditions (≲3.5 Ga, Late Hesperian – Amazonian). We find net sedimentation rate <(4-8) μm/yr in the alluvial-fan deposits, using the frequency of craters that are interbedded with alluvial-fan deposits as a fluvial-process chronometer. Considering only the observed interbedded craters sets a lower bound of >20 Myr on the total time interval spanned by alluvial-fan aggradation, >103-fold longer than previous lower limits. A more realistic approach that corrects for craters fully entombed in the fan deposits raises the lower bound to >(100-300) Myr. Several factors not included in our calculations would further increase the lower bound. The lower bound rules out fan-formation by a brief climate anomaly. Therefore, during the Late Hesperian – Amazonian on Mars, persistent or repeated processes permitted habitable surface conditions. 1. Introduction. Large alluvial fans on Mars record one or more river-supporting climates on ≲3.5 Ga Mars (e.g. -
