The lithium isotope system is increasingly being applied to a variety of Earth science studies,
as the burgeoning literature attests; over 180 papers have been published in the last twelve …

Isotopic variations usually follow mass-dependent fractionation, meaning that the relative
variations in isotopic ratios scale with the difference in mass of the isotopes involved (eg …

The delivery of water to the inner Solar System, including Earth, is still a debated topic. A
preferential role for hydrated asteroids in this process is supported by isotopic …

All planetary materials sampled thus far vary in their relative abundance of the major isotope
of oxygen, 16O, such that it has not been possible to define a primordial solar system …

High‐precision bulk aluminum‐magnesium isotope measurements of calcium‐aluminum‐
rich inclusions (CAI s) from CV carbonaceous chondrites in several laboratories define a …

Meteorites, which are remnants of solar system formation, provide a direct glimpse into the
dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our …

We report on the mineralogy, petrography, and in situ measured oxygen-and magnesium-
isotope compositions of eight porphyritic chondrules (seven FeO-poor and one FeO-rich) …

The abundant phyllosilicate and carbonate minerals characterizing most of the returned
particles from asteroid Ryugu suggest a history of extensive aqueous alteration on its parent …

Chondrites consist of three major components: refractory inclusions (Ca, Al‐rich inclusions
[CAI s] and amoeboid olivine aggregates), chondrules, and matrix. Here, I summarize recent …

New measurements of mass-dependent calcium isotope effects in meteorites, lunar and
terrestrial samples show that Earth, Moon, Mars, and differentiated asteroids (eg, 4-Vesta …
