  2. Syrtis Major

  3. 20 km

  4. Physical properties After Heisinger and Head (2004)

  5. A From Kiefer (2004) A' After Heisinger and Head (2004)

  6. From Bibring et al., 2005

  7. After Mustard et al. (LPSC 36, 2005), Hamilton et al., (2003) and Hoefen et al., (2003)

  8. Interpretation: •Syrtis Major is a differentiated ultramafic volcanic complex- basaltic (gabbroic) or even more felsic units overlying abundant pyroxene- and olivine- rich lithologies (e.g, Skaergaard, Bushveld, Theo's Flow, etc.). *Give me an hour, I’ll convince Phil C. Why care?: • It’s in good global context and it’s border with Mg-rich opx and olivine-bearing, layered rocks in Nili Fossae defines global environmental change. But Wait, There’s More.....

  9. The Nili Fossae Noachian Section -Higher up, numerous conformable strata, most NOT dust covered but high Albedo. -low crater density supports the highly degraded “look” of the land. -Beautifully exposed ancient fluvial channels Interpretation: -An ancient fluvial environment with significant (but varying) degrees of denudation.

  22. The bonus- a possible absolute age? The Nakhlites FACT: Nakhlites unique among martian meteorites; CPX cumulates with "disequilibrium" Fa-rich (25-35% Fo) olivine. FACT: Seven specimens, all identical in crystallization age (1.3 ba) and ejection age (11 ma) . Both shared with Fo-rich Chassignites.

  23. Northeast Syrtis Major Got it All. • Well-exposed stratigraphy (history), including: -Hesperian volcanics, with hints of fluvial overprints. -The Hesperian / Noachian boundary. -layered Noachian terrain with high habitability potential -Can walk the section Downhill • Conservatively fits MSL goals and guidelines. -”Safe” flat, equatorial, low altitude, low dust landing site . -Good rover access to all stratigraphic levels . -The full range of materials MSL can exploit explore, most low albedo / low TI. -no ice or water now. • ADDED BONUS: A potential absolute age tie.

  24. The John Grant Slide ™ THANK YOU --To the organizers of the workshop for making it accessible to “outsiders”. --To the data providers, making outstanding image products available, and easier to access every day.
