Using synthetic models to understand the detecting ability of ground‐penetrating radar for water‐conducting structures in the bedrock of formerly glaciated site

Near Surface Geophysics, Volume 24, Issue 5, Page 669-692, October 2026.
Abstract Utilizing synthetic models for the interpretation of ground‐penetrating radar (GPR) profiles can aid in the detection of hydrogeological structures by identifying their signatures. In this study, finite difference (FD) forward modelling was used to understand the detection ability of 50 MHz GPR for (1) the quaternary deposit–bedrock contact ...

Geochemistry, Petrogenesis and Tectonic Signification of the I-Type Granitoids in Ladde-Gore (Northern Domain, North Cameroon)

International Journal of Geoinformatics and Geological Science
The Ladde-Gore region is located in the northern domain of the Pan-African chain in Cameroon. The present work deals with the petrography and geochemistry of the granitoids of the Ladde-Gore region. The granitoids in the study area consist of amphibole granite, amphibole-biotite granite, amphibole-biotite-muscovite granite, and granodiorite.

Sensitization of OSL Signals in Quartz and Provenance Implications: Insights From Multi‐Spectroscopic Analysis of Quartz From Multiple Geological Settings

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Quartz optically stimulated luminescence (OSL) sensitivity and electron spin resonance (ESR) signals have been empirically proposed as indicators of sediment provenance. OSL sensitivity is defined as luminescence produced per unit dose (Gray: Gy) per unit mass (mg).

The Malanjkhand copper (+ molybdenum) deposit, India: mineralization from a low-temperature ore-fluid of granitoid affiliation

, 1997
Copper and subordinate molybdenum mineralization at Malanjkhand occurs within a fracture-controlled quartz-reef enclosed in a pink granitoid body surrounded by grey-granitoids constituting the regional matrix.

Petrogenesis and tectonic implications of I-type and A-type granitoids in the Dachadaban area, North Qilian Orogenic Belt

Frontiers in Geochemistry
The North Qilian Orogenic Belt is a key region for understanding the evolution of the Paleo-Asian Ocean and continental accretion. The Dachadaban area preserves a complete ophiolite suite and coeval granitoid intrusions. Zircon and apatite U–Pb geochronology, whole-rock geochemistry, and Sr–Nd isotopic analyses were conducted on ...

Tracing Orogenic Evolution From Multi‐Detrital Mineral Records: U‐Pb Geochronology and Trace‐Element Constraints From Glacial Diamictites

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

Unraveling the Evolution of Silicic Volcanism in a Distributed Volcanic Field: Insights From Harrat Khaybar, Western Saudi Arabia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.
