A form of mobile lithosphere with mantle recycling was already operating on the Early Earth around 4.4 to 3.3 billion years ago, according to the application of machine learning to differentiate the source lithologies of zircons from Jack Hills Austr

Gangdese arc magmatism, Tibet, was initially dominated by fractional crystallization of mantle derived magmas, followed by the remelting of these rocks during collision. These two stages lead to the stratification of the juvenile continental crust

Neoproterozoic breakup of Rodinia resulted in the formation of several oceanic realms between dispersing cratons, which were later consumed during the assembly of Gondwana. In its western portion, the interior orogenic belts of Gondwana formed during

The basalt V-Ti redox proxy indicates that both of the Archean ambient and modified mantle exhibit a ~1.0 log unit increase in their evolution for most cratons, possibly derived by widespread crustal recycling.

Abstract Paleogeographic reconstruction of Precambrian terranes reworked by Phanerozoic orogens (e.g., the Tibetan Plateau) results in complex lithotectonic relations due to intracrustal reworking by tectonothermal events. Detrital zircon rare earth

This paper placed the identified Mariana type ophiolite within a global tectonic re-organization at ca. 530-520 Ma. Similar ophiolites, together with other geological and chemical proxies, newly constrained the timing of establishment of modern plate

Why Earth’s crust only started becoming widely preserved in the Eoarchaean, 500 Ma after planetary accretion, is poorly understood. Here, the authors document a shift to juvenile magmatic sources in the early Eoarchaean, linking crustal preservatio

Constraining the thermal state of the lithosphere is crucial to understanding geodynamic regime in early Earth. Here the authors reconstruct ~2.9–2.5 Ga thermal structure of continental lithosphere of the North China Craton using TTG and propose a

AbstractThe Ortosuu and Uchkuduk regions of the Tianshan orogen contain a volumetrically small series of basaltic rocks erupted primarily during the late Mesozoic-Paleogene. Petrology, chemical composition, and P-T geotherm data from xenoliths within
