Credit: Jean Lachat/University of Chicago Nicolas Dauphas, the Louis Block Professor in Geophysical Sciences, holds a chondrite meteorite that contains a puzzling mismatch in isotopic composition with Earth’s crust. The mismatch puzzles scientists because they long believed that Earth formed from planetary objects similar to meteorites. Dauphas and his colleagues present research this week in Nature that explains how this mismatch could have come about.
Chondrite meteorites contain a puzzling mismatch in isotopic composition with Earth’s crust. The mismatch puzzles scientists because they long believed that Earth formed from planetary objects similar to meteorites. For the past 10 years, scientists have been trying to understand why...
