Identification of the giant impactor Theia in lunar rocks

D Herwartz, A Pack, B Friedrichs, A Bischoff - Science, 2014 - science.org

The nature of Earth's building blocks as revealed by calcium isotopes

MC Valdes, M Moreira, J Foriel, F Moynier - Earth and Planetary Science …, 2014 - Elsevier
Calcium is the fifth most abundant element in the Earth and in chondrites and is a pure
lithophile element which does not partition into planetary cores. Therefore, the calcium …

Evidence for multiple magma ocean outgassing and atmospheric loss episodes from mantle noble gases

JM Tucker, S Mukhopadhyay - Earth and Planetary Science Letters, 2014 - Elsevier
The energy associated with giant impacts is large enough to generate global magma
oceans during Earth's accretion. However, geochemical evidence requiring a terrestrial …
