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 ...

On the topographic effects by Stokes’ formula
Journal of Geodetic Science, 2014 Traditional gravimetric geoid determination relieson Stokes’ formula with removal and restoration of thetopographic effects. It is shown that this solution is in errorof the order of the quasigeoid-to-geoid difference, which ismainly due to incomplete ...

Geophysical update of the diameter of the Zhamanshin impact structure, Kazakhstan
Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2284-2302, September 2026.Abstract The rim of the 0.9‐Ma‐old Zhamanshin impact crater in Kazakhstan is considered to be almost completely exposed via a series of hills surrounding a central flat area, indicating an apparent diameter of 14 km. This would make Zhamanshin the second largest impact crater of the Quaternary period. However, the overall geometry of these hills is not

Large (∼80 km) Shield Volcanoes on the Moon Possibly Fed by Shallow Magma Reservoirs
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Large shield volcanoes are among the most prominent volcanic structures on terrestrial bodies. The Moon, while volcanically very active in the past and hosting various volcanic features, seems to lack such large shield volcanoes. Here, we report the identification of two lunar volcanic domes (Prinz‐Harbinger and Theophilus) with diameters ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract We present array‐scale (∼500 × 500 km) anisotropic shear‐velocity models from two Pacific ocean‐bottom seismometer (OBS) arrays of the OBS Research in the Convecting Asthenosphere (ORCA) experiment: Young ORCA (∼43 Ma) and Old ORCA (∼90 Ma). Rayleigh‐wave phase velocities spanning 5–150 s are combined with Love‐wave phase velocities from 5 to ...

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Lava tubes are subsurface volcanic conduits formed during effusive basaltic eruptions and are considered key targets for planetary exploration. Orbital remote sensing on the Moon and Mars has identified numerous collapse pits interpreted as possible surface expressions of underlying lava tube systems. However, the limited resolution of current

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract The cause of the observed mare basalt asymmetry between the lunar nearside and farside remains a long‐lasting conundrum. In this study, we characterized the petrology and geochemistry of the Chang'e‐6 low‐Ti basalts from the lunar farside, performed petrological modeling of major elements and conducted Monte Carlo simulation of trace elements,

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.Abstract Despite the prevalence of rock glaciers in mountain environments, their ice volumes are poorly constrained. Rock glaciers persist in settings unable to support glaciers. They act as climate resilient water stores and refugia for cold‐adapted species while also posing a hazard to alpine communities. Imaging the entire internal structure of rock

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.Abstract We investigate the structure and tectonic environment in the crust and upper mantle beneath the North China Craton (NCC) by conducting a full‐waveform inversion of teleseismic P and its coda waves from densely distributed broadband seismic stations. A high‐resolution model involving P‐ and S‐wave velocities as well as density is constructed by
