A Reassessment of Petrochemistry of ~1.2 Ga Tonalitic Rocks of the Northern Tugela Terrane, Natal Metamorphic Belt, South Africa: Further Constraints on the Evolution of This Belt

Geological Journal, EarlyView.
Our petrochemical studies on ~1.2 Ga granitoids of the Natal Metamorphic Belt, South Africa, do not suggest any property similar to Phanerozoic‐style subduction‐related granitoids. Plot of Kotongweni Tonalite in Y versus Sr diagram (after Moyen 2011), note that most samples have Sr/Y < 50.

Aeromagnetic survey of los Humeros Caldera, México

Geofísica Internacional, 1978
Un levantamiento aeromagnético regional sobre la caldera de Los Humeros, Puebla, México, rindió una anomalía de tipo bipolar sobre la región central de la caldera. Esta anomalía se interpretó como causada por un prisma intrusivo fuertemente magnetizado a

The Estimation of Magnetite Prospective Resources Based on Aeromagnetic Data: A Case Study of Qihe Area, Shandong Province, China

Remote Sensing, 2021
In the Qihe area, the magnetic anomalies caused by deep and concealed magnetite are weak and compared with ground surveys, airborne surveys further weaken the signals. Moreover, the magnetite in the Qihe area belongs to a contact-metasomatic deposit, and

The Aurora Vent Field at the Transition From Magmatic Accretion to Tectonic Extension on Gakkel Ridge: Constraints From Microseismicity and Aeromagnetic Observations

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The Aurora hydrothermal vent field (AVF) is the first confirmed active vent system on the Arctic Ocean seafloor, located at the western end of the ultraslow spreading Gakkel Ridge. It marks a distinctive endmember among ridge‐axis hydrothermal systems, where volcanic construction and ultramafic influence co‐exist.

A Global Lithospheric Magnetic Field Model Derived From Multi‐Satellite Gradient Observations and Regional Aeromagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Using gradient data from the Macau Science Satellite‐1 (MSS‐1), CHAMP, Swarm‐A, and Swarm‐C satellites, together with aeromagnetic model data from China, we built the China‐specific Global Gradient Lithospheric Magnetic Model (CGGLM). The new model reaches spherical harmonic degree 140 and uses the Iteratively Re‐weighted Least‐Squares method ...
