Onset of plate tectonics by the Eoarchean
One of the most contentious areas of Earth Science today is when, or whether or not modern-
style plate tectonics was in operation in the Archean Eon. In this review we present evidence …

Identification of chondritic krypton and xenon in Yellowstone gases and the timing of terrestrial volatile accretion
Identifying the origin of noble gases in Earth's mantle can provide crucial constraints on the
source and timing of volatile (C, N, H2O, noble gases, etc.) delivery to Earth. It remains …

Nebular atmosphere to magma ocean: a model for volatile capture during Earth accretion
The origin and abundance of mantle volatiles present major questions for Earth's evolution.
Here we quantify volatile capture from an atmosphere derived from the solar nebula during …

Eoarchean contrasting ultra-high-pressure to low-pressure metamorphisms (< 250 to> 1000 C/GPa) explained by tectonic plate convergence in deep time
Abstract Greenland's Itsaq Gneiss Complex (IGC) shows Eoarchean (> 3600 Ma) 250–400°

Primordial helium‐3 exchange between Earth's core and mantle
Volatiles from the solar nebula are known to be present in Earth's deep mantle. The core
also may contain solar nebula‐derived volatiles, but in unknown amounts. Here we use …

The effect of diffusion on lithium isotope ratios in icelandic basalts
In recent years, diffusion has gained increasing recognition as an important process for
explaining the lithium (Li) isotope ratios (δ 7 Li) of magmatic systems. However, the role of …
