Geodynamic transition at 2.7 Ga in Earths largest craton
The first ca. 2.2 billion years of Earth history saw significant change; from a water-world dominated by an anoxic atmosphere and tonalitic continents, to the exposed... -

Construction of the Yilgarn Craton over 1.5 billion years
The Yilgarn Craton of Western Australia represents one of the largest pieces of Precambrian crust on Earth, and a key repository of information on the Meso-Neoarchean period.... -

Convergent margin metallogenesis constrains onset of subduction on Earth
Convergent margins are a hallmark feature of modern style plate tectonics. One expression of their operation is metallogenesis, which therefore may yield important insights into... -

Origin of Archean Pb isotope variability through open-system Paleoarchean...
Lead isotopic data implies that Th and U were fractionated from one another in Earth's early history, however, the origin of this fractionation is poorly understood. We report... -

Hf-Nd isotopes of Archean komatiites A Hadean component in the Neoarchean mantle
Komatiites are extinct volcanic rocks that formed by partial melting of 20-50% of their mantle source – a unique feature that allows us to understand the composition of the... -

Crustal evolution of the south-east Superior Craton and insights into...
Archean crustal evolution, and its tectonic paradigm, can be directly linked to the evolution of the mantle, the hydrosphere-atmosphere, oxygenation of the Earth, and the... -

Low δ18O volcanism in the Neoarchean Fortescue Group, Pilbara Craton
Archean greenstone belts are a vital window into the tectonostratigraphic processes that operated in the early Earth and the geodynamics that drove them. However, the majority...
