47th Lunar and Planetary Science Conference

The meeting highlights:  Postdoc, Fara Lindsay gave an oral presentation about the Martian meteorite NWA 7034 (“Black Beauty”), a water rich "Martian (basaltic breccia)"whose spectrum matches spectral measurements of the Martian dark plains. The 40Ar/39Ar results have sampled multiple thermal events. The presentation generated several thought-provoking comments on how the meteorite came together on the Martian surface.

Graduate student Jake Setera’s presented a poster describing a new twist on Ar-Thermochronology developed here at Rutgers that attracted several researchers, both 40Ar/39Ar practitioners and new potential collaborators. His work has many possible applications to meteoritic samples such as NWA 7034.

Annette Hilton (REU student from The College of Wooster), an American Museum of Natural History undergraduate intern working with Dr. Juliane Gross, gave an oral presentation on the origin and classification meteorite NWA 10401 that created quite a buzz. Several unsolicited comments (including one from Apollo astronaut Harrison (Jack) Schmitt- the only geologist who walked on the Moon) stated that the presentation was one of the best student presentations at this years LPSC meeting.
