Geophysical Investigation of a Thermal Field in Abu Dhabi, United Arab Emirates

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In the Abu Dhabi Emirate, near Madinat Zayed and Liwa, studies have identified high geothermal gradients and high‐heat‐flow areas. Assessing the geothermal potential in this region requires a detailed mapping of subsurface geological formations and their thermal properties.

Sr-Nd Systematics and REE distribution in the type magnesite deposits in Lower Riphean of South Urals province

Литосфера, 2016
The geochemistry and REE of magnesite and host carbonate rocks of two Lower Riphean deposits of the South Urals province (Satka and Ismakaevo ore fields) confirm the metasomatic nature of the magnesite.

Probability and Recurrence of Maximum Magnitude Based on Stochastic Modeling of Internal Fault Geometry

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The recognition that relay zones along faults can act as barriers to earthquake propagation implies that rupture size may not be random and earthquakes are constrained by fault geometry. Resolution and observational biases can, however, complicate the integration of actual fault zone geometries into deterministic modeling strategies, thereby ...

Petrogenesis and Tectonic Implication of the Newly Identified Rhyacian and Orosirian Orthogneisses in the Northwestern Part of the Gyeonggi Massif (Soyeonpyeongdo and Ganghwado Areas), South Korea: Constrained From Whole‐Rock Geochemistry and Zircon U‐Pb‐Hf Isotopic Compositions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Gyeonggi Massif is one of the major Precambrian basements in the Korean Peninsula where Paleoproterozoic orthogneiss and paragneiss were widely exposed. In this study, newly identified Rhyacian to Orosirian meta‐igneous rocks from the northwestern Gyeonggi Massif (Soyeonpyeongdo and Ganghwado areas) were investigated to elucidate their ...

The Mobility of Major and Trace Elements in EOC Minerals on Parent Chondrite Bodies

Geosciences
The combined EPMA and SIMS study of the geochemical features of olivine, low-Ca pyroxene and plagioclase in equilibrated ordinary chondrites (EOCs) has revealed the effect of thermal metamorphism on trace element concentrations in EOC silicate minerals ...

Investigating Layered Cratonic Lithosphere in the Fennoscandian Shield

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Cold, thick, and chemically depleted lithosphere with high seismic velocity and low attenuation characterizes continental cratons. However, discrepancies between xenolith‐based thermal constraints and those inferred from surface‐wave seismic models, together with the widespread observation of mid‐lithosphere discontinuities, challenge the ...

Pattern Formation in Rocks

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract This commentary concerns a two‐part paper by Regenauer‐Lieb et al. (2026a, 2026b) on pattern formation in deforming porous rocks. The theory developed in part I (https://doi.org/10.1029/2025GC012710) uses the general idea of Turing's reaction‐diffusion model of morphogenesis based on interactions between two types of diffusible chemical ...
