Seismic Insight on Basement Structure of the Extinct Mid‐Oceanic Ridge in Canada Basin, Arctic Ocean

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The most accepted theory for the formation of the Canada Basin is that it was created during 66° rotation of Arctic Alaska around the Euler pole located near the Mackenzie Delta sometime during the Mesozoic. Gravity and magnetic anomaly data are consistent with an extinct mid‐oceanic ridge (MOR) in the central basin.

Revised Pacific-Antarctic plate motions and geophysics of the Menard Fracture Zone [PDF]

, 2008
A reconnaissance survey of multibeam bathymetry and magnetic anomaly data of the Menard Fracture Zone allows for significant refinement of plate motion history of the South Pacific over the last 44 million years.

Provenance Reassessment of Eocene Turbidites, New Caledonia: Inferences for Obduction Models

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Provenance of pre‐obduction Eocene turbidites from New Caledonia is used to better constrain their geodynamic context and inform debate on subduction polarity. Chemical compositions of detrital clinopyroxenes in arenites are compared against potential sources.

Formation， evolution， and distribution law of Mesozoic-Paleozoic buried hills in Jiyang Depression

Youqi dizhi yu caishoulu
Buried hill is an essential field of oil-gas exploration in Jiyang Depression. Deepening the formation mechanisms and establishing a predictable classification scheme of buried hills are the key to the exploration of hidden buried hills.

Origin of the King's Trough Complex (North Atlantic): Interplay Between a Transient Plate Boundary and the Early Azores Mantle Plume

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The King's Trough cuts into an area of thickened oceanic crust associated with the 45°N melting anomaly at the Mid‐Atlantic Ridge. Here we present a comprehensive geochemical data set and new 40Ar/39Ar age and bathymetric data from magmatic rocks from the King's Trough and the smaller Peake and Freen Deeps to the east and from the Gnitsevich ...

Geology of the San Colombano hill, a Quaternary isolated tectonic relief in the Po Plain of Lombardy (Northern Italy)

Journal of Maps, 2018
The 1:10,000 geological map of the San Colombano hill covers 60 km2 in the Po Plain, south of Milan. The new and the historical surface geological data-sets are managed by a GeoDB aiming to contribute to re-interpret the Quaternary evolution at the Po ...

Range‐Parallel Extension of the Andes in the 2020 Mw 5.7 Humahuaca Earthquake

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Normal‐faulting earthquakes in mountain ranges provide important constraints on the dynamics of mountain building. To date, well‐documented examples of range‐parallel extension come primarily from the Tibetan Plateau, limiting our ability to test different models for its cause.
