Dr. Philipp Heck, the Robert A. Pritzker Associate Curator for Meteoritics and Polar Studies and head of the Robert A. Pritzker Center, published a paper on atom-probe tomography of nanodiamonds from The Field Museum’s Allende meteorite in the journal Meteoritics & Planetary Science. This is the first application of the novel technique of Atom-Probe Tomography (APT) in the field of cosmochemistry.
Watch Meteorite Collections Manager Jim Holstein talk about what meteorites are at the Field Museum's popular science outreach show The BrainScoop. The Field Museum holds one of the largest and most important meteorite collections worldwide and the largest at a private research institution.
The meteorite, named Northwest Africa 7325, was found in Southern Morocco in early 2012 and likely comes from an asteroid in the space between Mars and Jupiter. The rock has puzzled scientists, leading one to speculate that it comes from the planet Mercury; however most researchers find this claim weak due to lack of evidence. This rock is an ungrouped achondrite and comes from a planetary body that has not been sampled before. Its study will enhance our picture of the diversity of planets in our solar system, and help better understand the formation of the planets, including Earth.
The Robert A. Pritzker Center for Meteoritics and Polar Studies welcomes Dr. Surya Snata Rout as its new Postdoctoral Research Scientist. Surya received his MS from the Indian Institute of Technology in Kharagpur, West Bengal, (studying the geochemical evolution of iron meteorites), and his Ph.D. from University of Münster in Germany. At Münster he investigated the mineralogy and chemistry of the rare R Chondrites meteorites, as well as space weathering on the planet Mercury.
