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…

Planetary Genealogy

Christoph Burkhardt

The detection of exoplanets and accretion disks around newborn stars has spawned new ideas and models of how our Solar System formed and evolved. Meteorites as probes of geologic d…

Terrestrial planet formation from lost inner solar system material

Christoph Burkhardt, Fridolin Spitzer, Alessandro Morbidelli +4

Two fundamentally different processes of rocky planet formation exist, but it is unclear which one built the terrestrial planets of the solar system. Either they formed by collisio…

Earth's accretion inferred from iron isotopic anomalies of supernova nuclear statistical equilibrium origin

Timo Hopp, Nicolas Dauphas, Fridolin Spitzer +2

Nucleosynthetic Fe isotopic anomalies in meteorites may be used to reconstruct the early dynamical evolution of the solar system and to identify the origin and nature of the materi…

Nucleosynthetic Pt isotope anomalies and the Hf-W chronology of core formation in inner and outer solar system planetesimals

Fridolin Spitzer, Christoph Burkhardt, Francis Nimmo +1

The 182Hf-182W chronology of iron meteorites provides crucial information on the timescales of accretion and differentiation of some of the oldest planetesimals of the Solar System…

Collisional mixing between inner and outer solar system planetesimals inferred from the Nedagolla iron meteorite

Fridolin Spitzer, Christoph Burkhardt, Jonas Pape +1

The ungrouped iron meteorite Nedagolla is the first meteorite with bulk Mo, Ru, and Ni isotopic compositions that are intermediate between those of the non-carbonaceous (NC) and ca…

Early evolution of the solar accretion disk inferred from Cr-Ti-O isotopes in individual chondrules

Jonas M. Schneider, Christoph Burkhardt, Yves Marrocchi +2

Isotopic anomalies in chondrules hold important clues about the dynamics of mixing and transport processes in the solar accretion disk. These anomalies have been interpreted to ind…

Isotopic evolution of the inner Solar System inferred from molybdenum isotopes in meteorites

Fridolin Spitzer, Christoph Burkhardt, Gerrit Budde +3

The fundamentally different isotopic compositions of non-carbonaceous (NC) and carbonaceous (CC) meteorites reveal the presence of two distinct reservoirs in the solar protoplaneta…

Elemental and isotopic variability in solar system materials by mixing and processing of primordial disk reservoirs

Christoph Burkhardt, Nicolas Dauphas, Ulrik Hans +2

Isotope anomalies among planetary bodies provide key constraints on planetary genetics and the Solar System's dynamical evolution. However, to unlock the full potential of these an…

Mixing and transport of dust in the early solar nebula as inferred from titanium isotope variations among chondrules

Simone Gerber, Christoph Burkhardt, Gerrit Budde +2

Chondrules formed by the melting of dust aggregates in the solar protoplanetary disk and as such provide unique insights into how solid material was transported and mixed within th…

Planetary and meteoritic Mg/Si and d30Si variations inherited from solar nebula chemistry

Nicolas Dauphas, Franck Poitrasson, Christoph Burkhardt +2

The bulk chemical compositions of planets are uncertain, even for major elements such as Mg and Si. This is due to the fact that the samples available for study all originate from…
