Physicochemical Controls on the Compositions of the Earth and Planets
Paolo A. Sossi, Remco C. Hin, Thorsten Kleine +2
Despite the fact that the terrestrial planets formed from the protoplanetary disk, their compositions show marked departures from that of solar nebula condensates. Metallic cores f…
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…
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)…
