[HTML][HTML] Stirred not shaken; critical evaluation of a proposed Archean meteorite impact in West Greenland
Large meteorite impacts have a profound effect on the Earth's geosphere, atmosphere,
hydrosphere and biosphere. It is widely accepted that the early Earth was subject to intense …

Lu–Hf, Sm–Nd, and U–Pb isotopic coupling and decoupling in apatite
Apatite is a useful geochronological tool due to its common occurrence and incorporation of
a variety of radioactive parent isotopes during crystallisation. However, an understanding of …

Archean sodic metagranitoids from the Southern São Francisco Craton: Review, petrogenesis, and tectonic implications
Gray gneiss complexes comprise most of the Archean crust in the Southern São Francisco
Craton and its surroundings, and their metagranitoid components can be distinguished …

Dating mylonitic overprinting of ancient rocks
Deformation in shear zones is difficult to date because mylonites can preserve partially reset
pre-existing isotopic signatures. However, mylonites can be key structural elements in …

Isotopic modelling of Archean crustal evolution from comagmatic zircon–apatite pairs
The composition of Earth's early crust is challenging to assess as only a fragmented record
remains. As a consequence, deciphering the composition of early crust as a means to …
