The Role of Orogenic Collapse on Tectonic Inheritance of Passive Continental Margins

Tectonics, Volume 44, Issue 1, January 2025.
Abstract The break‐up and drift of continents is governed by the reactivation of structures in the lithosphere that occur in preference to formation of new structures during rifting. Numerical analyses indicate that mantle heterogeneities should be a first‐order control on tectonic inheritance; however, the importance of mantle relative to crustal ...

A Self-Supervised Method of Suppressing Interference Affected by the Varied Ambient Magnetic Field in Magnetic Anomaly Detection

Remote Sensing
Airborne magnetic anomaly detection is an important passive remote sensing technique. However, since the magnetic field caused by the aircraft interferes with the detection accuracy, this part of interference should be eliminated by an aeromagnetic ...

Broadband seismic data acquisition and processing of iron oxide deposits in Blötberget, Sweden

Geophysical Prospecting, Volume 73, Issue 1, Page 80-95, January 2025.
Abstract In June 2022, an innovative seismic survey was conducted in Blötberget, central Sweden, to evaluate the effectiveness of employing both a broadband seismic source and broadband receivers for mineral exploration in a challenging hardrock setting. The Blötberget mine hosts high‐quality iron oxides, predominantly magnetite and hematite, sometimes

Ground Magnetic Mapping of Basement Structures of Maar Lake Tizong and Its Surroundings (Mandji/Wakwa, Adamawa, Cameroon)

International Journal of Geophysics, Volume 2025, Issue 1, 2025.
The Ngaoundéré area, marked by a complex geodynamic context, is characterized by ancient and recent tectonic activities, as well as intraplate volcanism linked to the Cameroon volcanic line (CVL). Ground magnetic mapping is an effective geophysical tool for detecting hidden faults or fractures and magnetic intrusions.

Processing of unmanned underwater vehicle vector magnetometer data

Geophysical Prospecting, Volume 72, Issue 8, Page 2902-2918, October 2024.
Abstract Marine magnetometry very close to the targeted sources, even in very deep waters, is today a reality with the advent of autonomous underwater vehicles. We argue that a successful approach is to fully integrate the magnetometer onboard the autonomous underwater vehicle and to deal with its static magnetic noise, that is induced and permanent ...

Seismic Reflection Profiling Reveals New Accretionary Structure in the Solonker Zone of the Central Asian Orogenic Belt

Geophysical Research Letters, Volume 51, Issue 16, 28 August 2024.
Abstract The Central Asian Orogenic Belt (CAOB) was formed by the aggregation and collage of numerous Paleozoic subduction‐accretion assemblages and Precambrian microcontinental blocks. However, the tectonic nature of the southeastern CAOB remains controversial, which complicates the reconstruction of the Paleo‐Asian Ocean.

Comparison between crustal density and velocity variations in southern California [PDF]

, 2001
We predict gravity from a three-dimensional V_p model of the upper crust and compare it to the observed isostatic residual gravity field. In general this comparison shows that the isostatic residual gravity field reflects the density variations in the ...
