Open AccessMagmatic record of India-Asia collision
New geochronological and geochemical data on magmatic activity from the India-Asia collision zone enables recognition of a distinct magmatic flare-up event that we ascribe to slab breakoff. This tie-point in t...

Open AccessCorrection: Corrigendum: Magmatic record of India-Asia collision
New geochronological and geochemical data on magmatic activity from the India-Asia collision zone enables recognition of a distinct magmatic flare-up event that we ascribe to slab breakoff. This tie-point in t...

Open AccessA non-zircon Hf isotope record in Archean black shales from the Pilbara craton confirms changing crustal dynamics ca. 3 Ga ago
Plate tectonics and associated subduction are unique to the Earth. Studies of Archean rocks show significant changes in composition and structural style around 3.0 to 2.5 Ga that are related to changing tecton...

Open AccessCrustal growth and reworking: A case study from the Erguna Massif, eastern Central Asian Orogenic Belt
Despite being the largest accretionary orogen on Earth, the record of crustal growth and reworking of individual microcontinental massifs within the Central Asian Orogenic Belt (CAOB) remain poorly constrained...

Thermochemical lithosphere differentiation and the origin of cratonic mantle
Cratons record the early history of continental lithosphere formation, yet how they became the most enduring part of the lithosphere on Earth remains unknown1. Here we propose a mechanism for the formation of lar...

Open AccessCrustal rejuvenation stabilised Earth’s first cratons
The formation of stable, evolved (silica-rich) crust was essential in constructing Earth’s first cratons, the ancient nuclei of continents. Eoarchaean (4000–3600 million years ago, Ma) evolved crust occurs on ...

Open AccessThermal state and evolving geodynamic regimes of the Meso- to Neoarchean North China Craton
Constraining thickness and geothermal gradient of Archean continental crust are crucial to understanding geodynamic regimes of the early Earth. Archean crust-sourced tonalitic–trondhjemitic–granodioritic gneis...

Open AccessMariana-type ophiolites constrain the establishment of modern plate tectonic regime during Gondwana assembly
Initiation of Mariana-type oceanic subduction zones requires rheologically strong oceanic lithosphere, which developed through secular cooling of Earth’s mantle. Here, we report a 518 Ma Mariana-type subductio...

Open AccessOxidation of Archean upper mantle caused by crustal recycling
The redox evolution of Archean upper mantle impacted mantle melting and the nature of chemical equilibrium between mantle, ocean and atmosphere of the early Earth. Yet, the origin of these variations in redox ...

Open AccessInterplay between oceanic subduction and continental collision in building continental crust
Generation of continental crust in collision zones reflect the interplay between oceanic subduction and continental collision. The Gangdese continental crust in southern Tibet developed during subduction of th...

Open AccessA resource for automated search and collation of geochemical datasets from journal supplements
This article presents a resource for automated search, extraction and collation of geochemical and geochronological data from the Figshare repository using web scra** code. To answer fundamental questions ab...
