We review the oxygen isotopic compositions of chondrite components (refractory inclusions,
chondrules, and matrix) and their inter-and intra-crystalline oxygen isotopic distributions …

Hydrogen is one of the possible alloying elements in the Earth's core, but its siderophile
(iron-loving) nature is debated. Here we experimentally examined the partitioning of …

We review the geochemical observations of water, D/HD/H and volatile element
abundances of the inner Solar System bodies, Mercury, Venus, the Moon, and Mars. We …

Crystallization in Earth's deep magma ocean could have caused trace element fractionation
in the lower mantle that might be inherited to the isotopic compositions of the present-day …

Oxygen isotopic composition of our solar system is believed to have resulted from mixing of
two isotopically distinct nebular reservoirs, 16O-rich and 17, 18O-rich relative to Earth. The …

Meteorite studies suggest that each solar system object has a unique oxygen isotopic
composition. Chondrites, the most primitive of meteorites, have been believed to be derived …

The objective of this study was to elucidate the transfer of nutrient elements in orchid
symbiotic protocorms at the cellular level by imaging of stable isotope tracers. We address …

Primitive chondritic meteorites contain material (presolar grains), at the level of a few parts
per million, that predates the formation of our Solar System. Astronomical observations and …

The high D/H of the Martian atmosphere (∼ 5–6× terrestrial) is considered strong evidence
for the loss of Martian water to space. The timing and magnitude of the loss of water from …

This paper describes the development of a technique using NanoSIMS to make precise and
accurate determination of the hydrogen isotopic composition and the hydroxyl content of …
