An unexpected source of Earth's water The abundances of Earth's chemical elements and their isotopic ratios can indicate which materials formed Earth. Enstatite chondrite (EC) meteorites provide a good isotopic match for many elements but are expected to contain no water because they formed in the hot inner Solar System. This would require Earth's water to be from a different source, such as comets. Piani et al. measured hydrogen contents and deuterium/hydrogen ratios (D/H) in 13 EC meteorites… 

A pristine record of outer Solar System materials from asteroid Ryugu’s returned sample

Volatile and organic-rich C-type asteroids may have been one of the main sources of Earth’s water. Our best insight into their chemistry is currently provided by carbonaceous chondritic meteorites,

Numerous chondritic impactors and oxidized magma ocean set Earth’s volatile depletion

It is shown that the BSE depletion pattern can be reproduced from continuous accretion of chondritic bodies by the partitioning of C into the core and H storage in the magma ocean in the main accretion stage and atmospheric erosion of N in the lateAccretion stage.

The Origin of Earth's Mantle Nitrogen: Primordial or Early Biogeochemical Cycling?

Earth's mantle nitrogen (N) content is comparable to that found in its N‐rich atmosphere. Mantle N has been proposed to be primordial or sourced by later subduction, yet its origin has not been

Enstatite chondrites are a small clan of meteorites, only ~ 1% out of all meteorite collection. However, they are the most reduced meteorites and have almost identical isotopic compositions to those

Tungsten Isotopic Constraints on the Nature of Earth's Accreting Materials

Tungsten isotope is a powerful tracer for the Earth's accreting materials because of the distinct W isotope compositions of the non‐carbonaceous meteorites and carbonaceous meteorites. To better

Constraints on Chondrule Generation, Disk Dynamics, and Asteroid Accretion from the Compositions of Carbonaceous Meteorites

The elemental and isotopic compositions of meteorites are expected to reflect several key processes that occurred in the early solar system, including the migration of gas and dust throughout the

Hydrothermal Activities on C-Complex Asteroids Induced by Radioactivity

C-complex asteroids, rich in carbonaceous materials, are potential sources of Earth’s volatile inventories. They are spectrally dark resembling primitive carbonaceous meteorites, and thus, C-complex

Evidence for primordial water in Earth’s deep mantle

Data for Baffin Island and Icelandic lavas are presented, which suggest that the deep mantle has a low D/H ratio (δD more negative than –218 per mil), which indicates the existence of a component within Earth’s interior that inherited its D/h ratio directly from the protosolar nebula.

The isotopic nature of the Earth’s accreting material through time

It is shown that elements with distinct affinities for metal can be used to decipher the isotopic nature of the Earth’s accreting material through time, and indicates that the giant impactor that formed the Moon probably had an isotopic composition similar to that of theEarth, hence relaxing the constraints on models of lunar formation.

Molybdenum isotopic evidence for the late accretion of outer Solar System material to Earth

Earth grew through collisions with Moon-sized to Mars-sized planetary embryos from the inner Solar System, but it also accreted material from greater heliocentric distances1,2, including carbonaceous

The Provenances of Asteroids, and Their Contributions to the Volatile Inventories of the Terrestrial Planets

Hydrogen isotopic analysis of primitive meteorites implicates asteroids as early sources of Earth’s water and argues against an influx of water ice from the outer solar system, which has been invoked to explain the nonsolar oxygen isotopic composition of the inner solar system.

Ruthenium isotopic evidence for an inner Solar System origin of the late veneer

It is shown that all chondrites, including carbonaceous chondrite-like asteroids or comets, have Ru isotopic compositions distinct from that of the Earth’s mantle, implying that the late veneer was not the primary source of volatiles and water on the Earth.

Terrestrial exposure of a fresh Martian meteorite causes rapid changes in hydrogen isotopes and water concentrations

The findings reveal the rapidity with which terrestrial weathering affects nominally anhydrous phases in extraterrestrial materials, which illustrates the necessity of sampling the interiors of even relatively fresh meteorite falls and underlines the importance of sample return missions.

The concentration and distribution of water in the Earth has influenced its evolution throughout its history. Even at the trace levels contained in the planet’s deep interior (mantle and core), water

Low hydrogen contents in the cores of terrestrial planets

A simple water budget suggests that 90% of the water initially present in planetary building blocks was lost during planetary accretion and the retained water segregated preferentially into planetary mantles.
