Origin of moderately volatile elements in Earth inferred from mass-dependent Ge isotope variations among chondrites
Elias Wölfer, Elias Wölfer, Christoph Burkhardt +2
The bulk silicate Earth (BSE) is depleted in moderately volatile elements, indicating Earth formed from a mixture of volatile-rich and -poor materials. To better constrain the orig…
Comparison of the earliest NC and CC planetesimals: Evidence from ungrouped iron meteorites
Fridolin Spitzer, Christoph Burkhardt, Thomas S. Kruijer +1
Isotope anomalies in meteorites reveal a fundamental dichotomy between non-carbonaceous- (NC) and carbonaceous-type (CC) planetary bodies. Until now, this dichotomy is established…
Did the terrestrial planets of the Solar System form by pebble accretion?
Alessandro Morbidelli, Thorsten Kleine, Francis Nimmo
The dominant accretion process leading to the formation of the terrestrial planets of the Solar System is a subject of intense scientific debate. Two radically different scenarios…
Mechanisms and timing of carbonaceous chondrite delivery to the Earth
Francis Nimmo, Thorsten Kleine, Alessandro Morbidelli +1
The nucleosynthetic isotope signatures of meteorites and the bulk silicate Earth (BSE) indicate that Earth consists of a mixture of "carbonaceous" (CC) and "non-carbonaceous" (NC)…
