Integrated Multi‐Physics Characterisation of the Northern Kiruna Mining District With Machine‐Learning‐Assisted Interpretation

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT Integrated earth modelling aims to combine all available geoscientific information to derive one common earth model. However, combining multiple parameters in a meaningful way remains challenging. In this study, we aim to improve mineral exploration workflows through the integration of new magnetotelluric data with other geophysical and ...

Chemical Significance and Chronology of Mesoproterozoic clastic rocks in Huainan Area

Chemical Engineering Transactions, 2018
After the 1.8Ga cracking event, the North China Craton entered the development stage of paraplatform, its southern margin, the Huainan area is in lack of accurate age data, so its stratigraphic sedimentation time limit has been controversial.

Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

Hydrogen‐Enhanced Grain Boundary Conductivity Explains High‐Conductivity Anomalies in Trans‐Lithospheric Shear Zones

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Magnetotelluric (MT) surveys reveal high electrical conductivity anomalies along major trans‐lithospheric shear zones. Given that trans‐lithospheric shear zones are proposed conduits for deep‐Earth volatiles, we employ molecular dynamics simulations to quantify H+ diffusivity and electrical conductivity at olivine grain boundaries.

Mesozoic–Cenozoic Thermochronology of the Tarim–Southern Tianshan System, NW China

Geological Journal, Volume 61, Issue 8, Page 2258-2278, August 2026.
Tectonothermal history of the Tarim–Southern Tianshan system compared with the major tectonic events at far‐field plate margins. ABSTRACT The Tarim Basin, an oil‐bearing basin in northwest China, is tectonically and sedimentologically linked to the Southern Tianshan Orogenic Belt.

Tracing Continental Basalt Sources and Mantle Processes Using Fe Stable Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Iron (Fe) isotopes have emerged as powerful tracers of mantle source heterogeneity and melting processes, yet the mechanisms producing heavy Fe isotope signatures (high δ57Fe values) in intraplate basalts remain debated. Competing interpretations include partial melting of recycled pyroxenite domains versus carbonate‐induced oxidation of a ...

Vanadium Isotopic Compositions of the High‐3He/4He Baffin Island Lavas

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The isotopic composition of vanadium (V) in hotspot lavas provides new insight into the source of deep mantle heterogeneities. We measured V isotopic compositions in Paleogene Baffin Island lavas, which erupted above the Iceland plume head, to constrain the mantle plume source. These lavas have V isotopic compositions that are lighter (−0.96 ±

Formation and evolution of the Archean continental crust of China: A review

China Geology, 2018
: The mainland of China is composed of the North China Craton, the South China Craton, the Tarim Craton and other young orogenic belts. Amongst the three cratons, the North China Craton has been studied most and noted for its widely-distributed Archean ...
