Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton

open access: yesGeophysical Research Letters
Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction.

Petrochemical and petrophysical characterization of the lower crust and the Moho beneath the West African Craton, based on Xenoliths from Kimberlites [PDF]

open access: yes
Additional evidence to the composition of the lower crust and uppermost mantle was presented in the form of xenolith data. Xenoliths from the 2.7-Ga West African Craton indicate that the Moho beneath this shield is a chemically and physically gradational

Opportunities for targeted, small‐scale law reform in marine and coastal restoration

open access: yesRestoration Ecology, Volume 34, Issue S1, May 2026.
Across the globe, law reform is being considered as a mechanism to support, guide, and encourage the upscaling of ecological restoration. While high‐profile examples like the European Nature Restoration Law show the value of large‐scale law reform, this scale of law reform will not be feasible or politically tractable everywhere.

A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

Fossil Subduction Zone Beneath the Eastern Yangtze Craton: Evidence From Seismic Reflections in the Upper Mantle

open access: yesGeophysical Research Letters
The Yangtze Craton in South China is generally regarded as an Archean‐Paleoproterozoic continental nucleus with a coherent basement that collided with the Cathaysia Block in the Early Neoproterozoic.

Archean foreland basin tectonics in the Witwatersrand, South Africa [PDF]

open access: yes
The Witwatersrand Basin of South Africa is the best-known of Archean sedimentary basins and contains some of the largest gold reserves in the world. Sediments in the basin include a lower flysch-type sequence and an upper molassic facies, both of which ...

Tectonic evolution of the Archaean high-grade terrain of South India [PDF]

open access: yes
The southern Indian shield consists of three major tectonic provinces viz., (1) Dharwar Craton, (2) Eastern Ghat Mobile Belt, and (3) Pandyan Mobile Belt. An understanding of their mutual relations is crucial for formulating crustal evolution models. The

Geochemical characteristics of charnockite and high grade gneisses from Southern Peninsular Shield and their significance in crustal evolution [PDF]

open access: yes
Presented here are the results of detailed investigations encompassing externsive structural mapping in the charnockite-high grade gneiss terrain of North Arcot district and the type area in Pallavaram in Tamil Nadu supported by petrography, mineral ...
