Boron isotope variations in tourmaline from hydrothermal ore deposits: a review of controlling factors and insights for mineralizing systems
Tourmaline group minerals are typically the predominant host of boron in hydrothermal
mineral deposits. Boron is a fluid-mobile element whose isotopic composition reflects many …

[HTML][HTML] Archaean plate tectonics in the North Atlantic craton of West Greenland revealed by well-exposed horizontal crustal tectonics, island arcs and tonalite …
AA Garde, BF Windley, TF Kokfelt… - Frontiers in Earth Science, 2020 - frontiersin.org
The 700 km-long North Atlantic Craton (NAC) in West Greenland is arguably the best
exposed and most continuous section of Eo-to Neoarchaean crust on Earth. This allows a …

[HTML][HTML] Archaean continental crust formed from mafic cumulates
Large swaths of juvenile crust with tonalite-trondhjemite-granodiorite (TTG) composition
were added to the continental crust from about 3.5 billion years ago. Although TTG …

Dominance of felsic continental crust on Earth after 3 billion years ago is recorded by vanadium isotopes
The transition from mafic to felsic upper continental crust (UCC) is crucial to habitability of
Earth, and may be related to the onset of plate tectonics. Thus, defining when this crustal …

The nature of subduction system in the Neoarchean: Magmatic records from the northern Yangtze Craton, South China
The Neoarchean is an important era during which plate tectonics began to operate widely
on Earth. The style of plate tectonics in the Neoarchean should be different but poorly …

Tectonics of the Isua Supracrustal Belt 1: P‐T‐X‐d constraints of a poly‐metamorphic terrane
Abstract The Eoarchean Isua supracrustal belt (ISB) has been interpreted as one of the
earliest records of subduction processes, leading to the conclusion that a plate tectonic …

[HTML][HTML] Eoarchean subduction-like magmatism recorded in 3750 Ma mafic–ultramafic rocks of the Ukaliq supracrustal belt (Québec)
Our understanding of the nature of crustal formation in the Eoarchean is limited by the
scarcity and poor preservation of the oldest rocks and variable and imperfect preservation of …
