Tollenaar V.* Zekollari H. Kittel C. Farinotti D. Lhermitte S. et al.

The Future of Antarctic Meteorites [#6382]
Antarctic meteorites are threatened by climate warming. Data-driven analyses indicate that meteorite losses exceed recovery rates by a factor of 5. The results motivate an intensification of recovery missions, prioritizing prone low-elevation areas.

1:45 PM

Karner J. M.* Schutt J. S. Harvey R. P. Rougeux B.

Meteorite Concentration Settings and Search Techniques at Davis Nunataks — Mt. Ward, Antarctica [#6441]
The Davis Nunataks- Mt. Ward icefields in Antarctica have yielded over 3400 meteorites; here's where and how we find them.

2:00 PM

Gattacceca J.* Kuzina D. Pyataev A. Sadaka C. Braucher R. et al.

A Magnetic Clock to Estimate the Terrestrial Ages of Meteorites? [#6258]
Based on a dataset of of 150 meteorites from the Atacama Desert, we will discuss the possibility that magnetic properties can be used to estimate the terrestrial ages of ordinary chondrites.

2:15 PM

Mijjum M.* Tremblay M. M. Andrews B. J. McCoy T. J. Corrigan C. M. et al.

Effects of Subsample Heterogeneity and Diffusion Kinetics on the Cosmic Ray Exposure Ages of Enstatite (E) Chondrites [#6228]
We use micro-computed X-ray tomography and cosmogenic noble gas measurements to examine the effects of subsample heterogeneity on cosmic ray exposure ages. We also perform diffusion experiments to evaluate noble gas retention in E chondrites.

2:30 PM

Nishiizumi K.* Caffee M. W.

Solar Cosmic Ray Exposure of Shergottites: Yamato 002192 and 002712 [#6436]
Solar-cosmic-ray (SCR)-produced nuclide, 26Al in two Yamato shergottites as well as other shergottites were measured. The abundance of SCR produced nuclide provides orbital information of martian meteorites.

2:45 PM

Sadaka C.* Gattacceca J. Dumas F. Braucher R. Gounelle M. et al.

The Dense and Old Catalina Meteorite Collection, Atacama Desert, Chile [#6171]
We describe the outcome of several search campaigns in the Catalina DCA, in the Atacama Desert, Chile. We present a statistical analysis involving 1591 meteorites, in terms of classification, mass, pairing, meteorite density and terrestrial ages.

3:00 PM

Pinto G. A.* Tavernier A. Gattacceca J. Corgne A. Luais B. et al.

Local Climatic Conditions and Preservation of Chondrites in the Main Dense Collection Areas of the Atacama Desert [#6013]
Meteorites are primarily found in zones denominated dense collection areas. We performed a climatic characterization of the most productive dense collection areas in the Atacama Desert and their influence on ordinary chondrite preservation.

3:15 PM

Sanders T. J.* McMahon S. ten Kate I. L.

Towards a Quantitative Analysis of Exogenous Organics on the Early Earth [#6279]
We report on a literature review aimed at identifying gaps in our current knowledge that challenge the quantitative analysis of organics contributed to the early Earth by extraterrestrial impactors.

3:30 PM

Van den Neucker A.* Helbert J. Barraud O. D'Amore M. Verma N. et al.

The Spectral Characterization of the Ribbeck Aubrite as Mercury Analog [#6412]
MERTIS of the BepiColombo mission has as goal to characterize Mercury's surface mineralogy. To prepare for the upcoming remote sensing measurements, the aubrite meteorite Ribbeck was selected and studied for its microscopical and spectral properties.

3:45 PM

Schmitz B.* Heck P. R.

Classification of Meteorites from the Mid-Ordovician Sea Floor [#6283]
A systematic search during three decades for meteorites that fell on the Ordovician sea floor has now identified more than 140 specimens, 1–21 cm large. With one exception the meteorites are all ordinary chondrites and most likely L chondrites.

4:00 PM

Aboulahris M.* Chennaoui Aoudjehane H. Rochette P. Gattacceca J. Jull A. T. et al.

Palaeoclimate of the Sahara and Its Relation to Meteorites [#6393]
The Sahara has experienced alternating phases of hyperaridity and humid phases linked to changes in major atmospheric currents. we will discuss the relationship between the paleoclimate of the Sahara and the terrestrial age of meteorites.
