Magnesium isotope geochemistry

FZ Teng - Reviews in Mineralogy and Geochemistry, 2017 - pubs.geoscienceworld.org
Magnesium (Mg) has an atomic number of 12 and belongs to the alkaline earth element
(Group II) of the Periodic Table. The pure Mg is a silvery white metal and has a melting point …

The great isotopic dichotomy of the early Solar System

TS Kruijer, T Kleine, LE Borg - Nature Astronomy, 2020 - nature.com
The isotopic composition of meteorites and terrestrial planets holds important clues about
the earliest history of the Solar System and the processes of planet formation. Recent work …

The effect of Jupiter's formation on the distribution of refractory elements and inclusions in meteorites

SJ Desch, A Kalyaan… - The Astrophysical Journal …, 2018 - iopscience.iop.org
We present a comprehensive evolutionary model of the Sun's protoplanetary disk,
constructed to resolve the" CAI storage problem" of meteoritics. We predict the abundances …

A unified chronology of dust formation in the early solar system

M Piralla, J Villeneuve, N Schnuriger, DV Bekaert… - Icarus, 2023 - Elsevier
The chronology of dust formation in the early solar system remains controversial.
Chondrules are the most abundant high-temperature objects formed during the evolution of …

Magnesium isotopic composition of the Earth and chondrites

FZ Teng, WY Li, S Ke, B Marty, N Dauphas… - … et Cosmochimica Acta, 2010 - Elsevier
To constrain further the Mg isotopic composition of the Earth and chondrites, and investigate
the behavior of Mg isotopes during planetary formation and magmatic processes, we report …

Mass fractionation laws, mass-independent effects, and isotopic anomalies

N Dauphas, EA Schauble - Annual Review of Earth and …, 2016 - annualreviews.org
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 pH of Enceladus' ocean

CR Glein, JA Baross, JH Waite Jr - Geochimica et Cosmochimica Acta, 2015 - Elsevier
Saturn's moon, Enceladus, is a geologically active waterworld. The prevailing paradigm is
that there is a subsurface ocean that erupts to the surface, which leads to the formation of a …

The age of the Solar System redefined by the oldest Pb–Pb age of a meteoritic inclusion

A Bouvier, M Wadhwa - Nature geoscience, 2010 - nature.com
The age of the Solar System can be defined as the time of formation of the first solid grains in
the nebular disc surrounding the proto-Sun. This age is estimated by dating calcium …

U–Pb chronology of the Solar System's oldest solids with variable 238U/235U

Y Amelin, A Kaltenbach, T Iizuka, CH Stirling… - Earth and Planetary …, 2010 - Elsevier
Accurate determination of the absolute ages of the oldest Solar System objects—chondrules
and Ca–Al-rich inclusions (CAIs), requires knowledge of their 238U/235U ratios. This ratio …

Evidence for magnesium isotope heterogeneity in the solar protoplanetary disk

KK Larsen, A Trinquier, C Paton… - The Astrophysical …, 2011 - iopscience.iop.org
With a half-life of 0.73 Myr, the 26 Al-to-26 Mg decay system is the most widely used short-
