Origin of moderately volatile elements in Earth inferred from mass-dependent Ge isotope variations among chondrites
Elias Wölfer, Christoph Burkhardt, Francis Nimmo +1
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…
The Ni isotopic composition of Ryugu reveals a common accretion region for carbonaceous chondrites
Fridolin Spitzer, Thorsten Kleine, Christoph Burkhardt +88
The isotopic compositions of samples returned from Cb-type asteroid Ryugu and Ivuna-type (CI) chondrites are distinct from other carbonaceous chondrites, which has led to the sugge…
Condensate evolution in the solar nebula inferred from combined Cr, Ti, and O isotope analyses of amoeboid olivine aggregates
Christian A. Jansen, Christoph Burkhardt, Yves Marrocchi +3
Refractory inclusions in chondritic meteorites, namely amoeboid olivine aggregates (AOAs) and Ca-Al-rich inclusions (CAIs), are among the first solids to have formed in the solar s…
Distribution of s-, r-, and p-process nuclides in the early Solar System inferred from Sr isotope anomalies in meteorites
Jonas M. Schneider, Christoph Burkhardt, Thorsten Kleine
Nucleosynthetic isotope anomalies in meteorites allow distinguishing between the non-carbonaceous (NC) and carbonaceous (CC) meteorite reservoirs and show that correlated isotope a…
Origin of isotopic diversity among carbonaceous chondrites
Jan L. Hellmann, Jonas M. Schneider, Elias Wölfer +5
Carbonaceous chondrites are some of the most primitive meteorites and derive from planetesimals that formed a few million years after the beginning of the solar system. Here, using…
