Oxygen isotopic evidence for vigorous mixing during the Moon-forming giant impact
Earth and the Moon are shown here to have indistinguishable oxygen isotope ratios, with a
difference in Δ′ 17O of− 1±5 parts per million (2 standard error). On the basis of these data …

Ruthenium isotopic evidence for an inner Solar System origin of the late veneer
The excess of highly siderophile elements in the Earth's mantle is thought to reflect the
addition of primitive meteoritic material after core formation ceased,,,. This 'late veneer'either …

Oxygen isotope identity of the Earth and Moon with implications for the formation of the Moon and source of volatiles
The Moon formed 4.5 Ga ago through a collision between proto-Earth and a planetesimal
known as Theia. The compositional similarity of Earth and Moon puts tight limits on the …

Water reservoirs in small planetary bodies: meteorites, asteroids, and comets
Asteroids and comets are the remnants of the swarm of planetesimals from which the
planets ultimately formed, and they retain records of processes that operated prior to and …

Ancient helium and tungsten isotopic signatures preserved in mantle domains least modified by crustal recycling
Rare high-3He/4He signatures in ocean island basalts (OIB) erupted at volcanic hotspots
derive from deep-seated domains preserved in Earth's interior. Only high-3He/4He OIB …

Lithophile and siderophile element systematics of Earth's mantle at the Archean–Proterozoic boundary: Evidence from 2.4 Ga komatiites
New Os isotope and highly siderophile element (HSE) abundance data, in combination with
lithophile trace element and Sm–Nd, Lu–Hf, and Hf–W isotope data, are reported for …

The NC-CC isotope dichotomy: Implications for the chemical and isotopic evolution of the early Solar System
Understanding the formation of our planetary system requires identification of the materials
from which it originated and the accretion processes that produced the planets. The …

Oxygen isotopic evidence for accretion of Earth's water before a high-energy Moon-forming giant impact
The Earth-Moon system likely formed as a result of a collision between two large planetary
objects. Debate about their relative masses, the impact energy involved, and the extent of …
