Field Museum researchers co-author a paper on a previously unknown type of meteorite that was found fossilized in a 470 million year old seabed.
A Field Museum research loan of iron meteorites that were made available to a group of researches in Germany led to the most accurate chronology to date of planetary core formation.
The group’s study finds that planetary cores formed very fast in geological terms, in about 1 million years after the first solids condensed in the solar system. For the first time the study finds also that cores of the parent bodies of different iron meteorites formed at different times. This was previously unknown and unresolvable because the analytical methods were not precise enough.
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.
