Session Introduction

2:20 PM

Duncan M. S.* Weller M. B.

Martian Mantle Melting: A Geochemical and Geodynamic Perspective [#2994]
Mantle melting needs / Geochem plus geophysics / Mars: an example.

2:30 PM

Aithala S. P.* Hirschmann M. M. Buss M.

Iron Redox Systematics of Martian Magmas [#1862]
We investigate the relationship between iron redox and oxygen fugacity in martian magmas to quantitatively model igneous mass transfer on Mars.

2:40 PM

Wu P.* Dayton K. Gazel E.

Quantitative Analysis of Melt Inclusions in Extraterrestrial Samples Using Nano-Scale X-Ray Computed Tomography [#2436]
This study demonstrates the capabilities of applying X-ray nano-CT on the study of melt inclusions hosted in extraterrestrial materials.

2:50 PM

Ramsey S.* Ostwald A. Udry A. Day J. M. D.

Parental Melt Composition of the Northwest Africa 13669 Nakhlite from Pyroxene and Olivine-Hosted Melt Inclusions [#1030]
A melt inclusion / In a crystal mush / Reequilibrates.

3:00 PM

Panel Q&A

3:20 PM

Jakosky B. M.*

Outgassing of Volatiles on Mars: Volcanism Through Time or Early Catastrophic Release? [#1013]
Measurements of volatiles in the atmosphere and in Mars meteorites answer this question. Volcanism can’t, pushing the major outgassing to the earliest history.

3:30 PM

Kleine T.* Steller T. Burkhardt C. Nimmo F.

An Inner Solar System Origin of Volatile Elements in Mars [#2409]
Nucleosynthetic Zn isotope anomalies reveal that Mars accreted volatile elements from its main inner solar system building blocks.

3:40 PM

Mukhopadhyay S.* Peron S. C.

Formation and Evolution of Mars Based on Differences in Its Interior and Atmospheric Volatiles [#2961]
Mars interior acquired chondritic volatiles followed by acquisition of solar gas in the atmosphere.

3:50 PM

Zimmermann N.* Safari M. Nekvasil H.

Trace Elements in Martian Fines: Contributions by Magmatic Gases [#2826]
We degassed a volatile (S,Cl,Br) and trace element doped P-Ca-Ti rich martian basalt to investigate the nature of vapor-deposited phases produced.

4:00 PM

Panel Q&A

4:20 PM

McSween H. Y.* Head J. W.

Ground-Truth Tests of Mars Magmatic Evolution Through Time [#1022]
Are temporal patterns in Mars magma compositions inferred from orbital remote-sensing consistent with ground-truth data from rover analyses and meteorites?

4:30 PM

Ostwald A. M.* Udry A. Day J. M. D. Gross J. Griffin S.

Complexly Zoned Crystals in the Nakhlite and Chassignite Meteorites and Implications for Petrogenesis [#1123]
Crystals in magma / Chronicle change during growth / In hidden patterns.

4:40 PM

Schmidt M. E.* Allwood A. Brown A. Christian J. Crumpler L. et al.

Sid: The Most Fractionated Martian Magma to Date and Its Crustal Evolution [#1368]
PIXL and SHERLOC indicate Jezero floor outcrop is porphyritic with zoned feldspars and very low Mg#, consistent with extensive fractionation of basaltic parent.

4:50 PM

Liu Y.* Allwood A. C. Treiman A. H. Schmidt M. E. Asimow P. D. et al.

The Nature of Igneous Olivine Cumulate Rocks in Jezero Crater, Mars [#1311]
Mineralogy and texture of olivine cumulate in Jezero crater, implication to regional unit.

5:00 PM

Panel Q&A
