Review of temporal trend in Archean granitoid chemistry-implications for Eoarchean (3.7–3.9 Ga) transition in geodynamic regime of crust formation
In this study, we review changes in Archean granitoid chemistry using stacked probability
density estimation and statistical change-point analyses. A significant change in Archean …

Correlating mantle cooling with tectonic transitions on early Earth
The dominant tectonic mode operating on early Earth (before ca. 2.5 Ga) remains elusive,
with an increasing body of evidence suggesting that non-plate tectonic modes were likely …

A giant impact origin for the first subduction on Earth
Hadean zircons provide a potential record of Earth's earliest subduction 4.3 billion years
ago. It remains enigmatic how subduction could be initiated so soon after the presumably …

Formation of silicic crust on early Earth and young planetary bodies in an Iceland-like setting
Four billion years ago, Earth's surface was covered with a thick basaltic crust and, similar to
other rocky planets and the Moon, parts of this basaltic crust underwent partial melting to …
