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…
