Poster Session: Martian Hydrated Minerals and Aqueous Alteration

Thursday, March 16, 2023, 6:30 PM
Town Center Exhibit Hall

Barbre K. S. R.* Elwood Madden M. E. Elwood Madden A. S. Hodges C. A.
Ferrihydrite Transformation Products in Near-Saturated Martian Brines [#1775]
This study discusses ferrihydrite stability and transformation products when mixed with near-saturated brines such as those observed on Mars.
Fries M. D.* Steele A.
A Cold Wet Mars: A Testable Hypothesis for Ancient Mars Ocean Freezing Point Depression via Low Molecular Weight Organics [#2954]
Mars waters ran free / But they should have iced over / Maybe antifreeze.
Riu L.* Ody A. Carter J.
Global Mapping of Hematite at Mars Using Visible OMEGA/MEx Hyperspectral Data [#1417]
We present the first attempt at mapping hematite at Mars using the OMEGA visible data. The overall aim of this study is the production of hematite global maps.
Sun V. Z. Voigt J. R. C.* Stack K. M.
Investigating Hydrated Silica in the Nili Patera Region, Mars [#1654]
We investigate hydrated silica in the Nili Patera region and the surrounding Syrtis Major Planum on Mars to constrain the longevity of aqueous conditions.
Carter J.* Pineau M. Mangold N. Le Deit L.
Late Stage Aqueous Alteration in the Northern Plains of Mars: Hydrated Silica is the Key [#1961]
Aqueous alteration signatures in the northern plains of Mars exhibit hydrated silica that are interpreted as late-stage sedimentary and igneous volcanism.
Pineau M.* Carter J. Chauviré B. Le Deit L. Mangold N.
In-Depth Study of the Silica-Rich Deposits in Western Hellas Basin, Mars [#1982]
This study reassesses the distribution and mineralogy of hydrated silica deposits in the Western Hellas Basin, Mars, and discusses their possible geological origins.
Klidaras A.* Navarre R. Horgan B. Farrand W. Goudge T.
Clay Stratigraphies on Ancient Mars: Building a Global Database [#2135]
We are building a database to record the mineralogy and stratigraphic properties of Noachian weathering profiles,in order to constrain the climate of early Mars.
Bonsall E.* Asimaki Z. Schröder C.
Comparing Diagenetic Aqueous Alteration Processes Observed at Different Mars Landing Sites [#2850]
Geochemical indicators identify rocks high in reactive iron phases and low diagenetic alteration. Such rocks can preserve organic compounds on Mars.
Singh A. P.* Chauhan M. Agrawal S.
Classification of Carbonates of Mars Using Machine Learning [#2303]
This study shows the potential of machine-learning-based algorithms for the classification of carbonates on Mars using CRISM.
Loche M.* Fabre S. Cousin A. Treiman A. Lanza N. et al.
The Fate of Manganese: Fractionation of Mn and Fe During the Kinetic Alteration Process [#2842]
In this work, we shows with a simultaneous dissolution and oxidation kinetic model that Mn/Fe fractionation occurs, and that Mn-oxide are challenging to form.
Aaron L. M.*
Modeling the Formation of Sulfates in the Noachian Crust of Mars [#2934]
Sulfate recipe / Martian stew, acidic broth? / Or non-acidic?
Kodikara G. R. L.* McHenry L. J. Grundl T. J. van der Meer F. D. Harris M. T.
Models, Modeling, Scientific Reasoning, and Terrestrial Perspective on Formation of Zeolites on Early Mars [#1140]
We examined the use of multiple hypotheses and different scientific reasoning to address why zeolites are not commonly observed in paleolake basins on Mars.
Knight A. L.* VanBommel S. J. Gellert R. Berger J. A. Catalano J. G. et al.
Analysis of Trace Element Concentrations by the Mars Exploration Rover Alpha Particle X-Ray Spectrometers: Implications for Diagenetic Fluids at Meridiani Planum and Gusev Crater [#2004]
We present trace-element (e.g., Ga and Ge) quantifications from the creation of composite MER APXS spectra based on geological characteristics.
