The Cadomian Orogen: Neoproterozoic to Early Cambrian crustal growth and orogenic zoning along the periphery of the West African Craton—Constraints from U-Pb zircon ages and Hf isotopes (Schwarzburg Antiform, Germany)
TLDR
In this paper, the Cadomian Orogen is inferred as a continental magmatic arc during the Neoproterozoic developed on a stretched Eoarchean to Hadean crust.About:

Continental arc volcanism as the principal driver of icehouse-greenhouse variability
N. Ryan McKenzie,N. Ryan McKenzie,N. Ryan McKenzie,Brian K. Horton,Shannon E. Loomis,Daniel F. Stockli,Noah J. Planavsky,Cin-Ty A. Lee +7 more
TL;DR: A compilation of ~120,000 detrital zircon uranium-lead ages from global sedimentary deposits as a proxy to track the spatial distribution of continental magmatic arc systems from the Cryogenian period to the present demonstrates a direct relationship between global arc activity and major climate shifts.

Collision vs. subduction-related magmatism: two contrasting ways of granite formation and implications for crustal growth
Jean-François Moyen,Oscar Laurent,Oscar Laurent,Cyril Chelle-Michou,Simon Couzinié,Olivier Vanderhaeghe,Armin Zeh,Arnaud Villaros,Véronique Gardien +8 more
TL;DR: In this paper, the authors examined the granitic suites in a late-collision environment, the Variscan French Massif Central (FMC), and compared them with the suites found in an oceanic arc.

The Brasiliano collage in South America: a review
TL;DR: A recent analysis of geochronological data from the basement of the South American platform indicates that the Brasiliano orogenic collage took place in four distinct pulses: a) Early Cryogenian (ca. 800 - 740Ma); b) Late Cryogenians-Early Ediacaran (c. 660 - 610 Ma); c) Early-Middle Ediacaris ( c. 590 - 560 Ma); and d) Late Cambrian (520 - 500 Ma) as mentioned in this paper.

Post-collisional magmatism: Crustal growth not identified by zircon Hf–O isotopes
Simon Couzinié,Oscar Laurent,Oscar Laurent,Jean-François Moyen,Armin Zeh,Armin Zeh,Pierre Bouilhol,Arnaud Villaros +7 more
TL;DR: This article showed that post-collisional mafic magmas and their derivatives represent a non-negligible contribution to crustal growth, despite having zircons with "crust-like" Hf-O isotope signatures.

Gondwanan basement terranes of the Variscan–Appalachian orogen: Baltican, Saharan and West African hafnium isotopic fingerprints in Avalonia, Iberia and the Armorican Terranes
Bonnie J. Henderson,William J. Collins,J. B. Murphy,Gabriel Gutiérrez-Alonso,Gabriel Gutiérrez-Alonso,Martin Hand +5 more
TL;DR: In this paper, a detrital zircon U-Pb-Hf dataset from Neoproterozoic-Silurian sedimentary sequences in NW Iberia and Avalonia, in conjunction with the comprehensive existing datasets from potential source cratons, is presented.

Approximation of terrestrial lead isotope evolution by a two-stage model
J.S. Stacey,Jan Kramers +1 more
TL;DR: In this paper, a two-stage model for terrestrial lead isotope evolution is proposed, which permits the age of the earth to be that of the meteorite system and also yields good model ages for samples of all ages.

Plesovice zircon : A new natural reference material for U-Pb and Hf isotopic microanalysis

TL;DR: The Plesovice zircon as discussed by the authors has a concordant U-Pb age with a weighted mean Pb-206/U-238 date of 337.13 +/- 0.37 Ma (ID-TIMS, 95% confidence limits, including tracer calibration uncertainty).

The Lu–Hf and Sm–Nd isotopic composition of CHUR: Constraints from unequilibrated chondrites and implications for the bulk composition of terrestrial planets
TL;DR: In this paper, the Lutetium-Hafnium radiogenic isotopic system is used as a chronometer and tracer of planetary evolution, and the Lu-Hf system parameters need to be more tightly constrained, in particular the LuHf isotopic composition of the chondritic uniform reservoir and, by extension, the bulk silicate Earth.
Journal ArticleDOI
Calibration of the lutetium-hafnium clock.
TL;DR: The existence of strongly unradiogenic hafnium in Early Archean and Hadean zircons implies that enriched crustal reservoirs existed on Earth by 4.3 billion years ago and persisted for 200 million years or more, and current models of early terrestrial differentiation need revision.

Evidence from detrital zircons for the existence of continental crust and oceans on the Earth 4.4 Gyr ago.
TL;DR: The discovery of a detrital zircon with an age as old as 4,404 ± 8 Myr is reported, about 130 million years older than any previously identified on Earth and represents the earliest evidence for continental crust and oceans on the Earth.
