Further characterisation of the 91500 zircon crystal
This paper reports the results from a second characterisation of the 91500 zircon, including data from electron probe microanalysis, laser ablation inductively coupled plasma-mass spectrometryExpand
Oxygen three-isotope fractionation lines in terrestrial silicate minerals: An inter-laboratory comparison of hydrothermal quartz and eclogitic garnet
Geochemical—and perhaps biochemical—processes may yield tell-tale proxies in rocks and minerals on the Earth or other planetary bodies, in the form of distinctive slopes of linear fractionationExpand
Pinpointing the Source of a Lunar Meteorite: Implications for the Evolution of the Moon
The isotope systematics of the meteorite record four lunar impact events at 3909 ± 13 million years ago, ∼2800 Ma, ∼200 Ma, and <0.34 Ma, which can be linked to the collision with Earth sometime after 9.7 ± 1.3 thousand years ago. Expand
Widespread magma oceans on asteroidal bodies in the early Solar System
It is shown that magma oceans were present on all the differentiated Solar System bodies so far sampled, and the modification of such bodies before incorporation into larger objects can explain some anomalous planetary features, such as Earth's high Mg/Si ratio. Expand
Crustal partial melting on Vesta: Evidence from highly metamorphosed eucrites
We have performed a mineralogical and geochemical study of eight metamorphosed basaltic eucrites. These are classified into granulitic eucrites and type 4–7 eucrites on the basis of their texturesExpand
Oxygen isotopic constraints on the origin and parent bodies of eucrites, diogenites, and howardites
Abstract A few eucrites have anomalous oxygen isotopic compositions. To help understand their origin and identify additional samples, we have analyzed the oxygen isotopic compositions of 18 eucritesExpand
The Stannern trend eucrites: Contamination of main group eucritic magmas by crustal partial melts
We report on the petrology of a new eucrite belonging to the Stannern trend and discuss the origin of this trend. The eucrite Northwest Africa 4523 (NWA 4523) is an equilibrated eucrite consisting ofExpand
Tissint Martian Meteorite: A Fresh Look at the Interior, Surface, and Atmosphere of Mars
Tissint (Morocco) is the fifth martian meteorite collected after it was witnessed falling to Earth and shows that it is a depleted picritic shergottite similar to EETA79001A, suggesting that it was ejected from Mars during the same event. Expand
Oxygen isotopic evidence for accretion of Earth’s water before a high-energy Moon-forming giant impact
It is shown that the bulk of Earth’s water was delivered before the high-energy collision that led to the formation of the Moon and not later, as often proposed. Expand
Petrography and geochemistry of the chassignite Northwest Africa 2737 (NWA 2737)
We report on the petrology and geochemistry of the Northwest Africa 2737 (NWA 2737) meteorite that was recovered from the Morrocan Sahara in 2000. It is the second member of the chassignite subclassExpand
