Analysis of recent geological and geochronological data from the basement of the South
American platform indicates that the Brasiliano orogenic collage took place in four distinct …

Abstract The Iapetus Ocean was the first ancient ocean to be identified following the
development of plate tectonics; its history has been fundamental in relating orogenesis and …

Abstract After its Ediacaran-Early Cambrian assembly, Gondwana was flanked by a system
of peripheral orogens, Terra Australis, Avalonian-Cadomian and newly defined North Indo …

Earth's continental crust is dominantly made of buoyant, felsic igneous material (granitoids),
that was ultimately extracted from the mantle as a result of Earth's differentiation. Since felsic …

Variations in continental volcanic arc emissions have the potential to control atmospheric
carbon dioxide (CO2) levels and climate change on multimillion-year time scales. Here we …

The combination of U–Pb, Lu–Hf and O isotopic analyses in global zircon databases has
recently been used to constrain continental crustal growth and evolution. To identify crust …

We present a statistical approach to data mining and quantitatively evaluating detrital age
spectra for sedimentary provenance analyses and palaeogeographic reconstructions …

Abstract Iberia, Avalonia and the “Armorican” terranes form key constituents of the Variscan–
Appalachian orogen, but their Neoproterozoic origins along the northern Gondwanan …

The late stages of the Variscan orogeny are characterized by middle to lower crustal melting
and intrusion of voluminous granitoids throughout the belt, which makes it akin to “hot” …

In tectonic maps of Variscan Europe, allochthonous pieces of Cadomian basement clearly
stand out with their predominant metabasic to ultrabasic elements, the so-called exotic …
