Geochemistry, Geophysics, Geosystems, 2021 The Earth's upper mantle is isotopically heterogeneous over large lengthscales, but the lower limit of these heterogeneities is not well quantified. Grain scale trace elemental variability has been observed in mantle peridotites, which suggests that ...

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal

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.

Geologica Carpathica, 2017 Xenoliths of garnet-biotite-kyanite schist from the Qori metamorphic complex (southern part of the Sanandaj-Sirjan zone, northeast Neyriz, Zagros orogen in Iran) in the 173.0±1.6 Ma Chah-Bazargan leuco-quartz diorite intrusion were studied.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.Abstract Vulcanian eruptions are classically associated with the launch of ballistic ejecta and particularly with the production of breadcrust bombs. Morpho‐textural analysis of these ejecta provides critical insight into the poorly constrained processes controlling the complex dynamics of Vulcanian activity.

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 ...

Tectonics, Volume 45, Issue 9, September 2026.Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...
