Unveiling Northern Antarctica's Marine‐Covered Continent‐Ocean Boundary and Characteristics Using Density and Magnetization Vector Structures

open access: yesGeophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The Antarctic continental margin, a critical transition zone between thin continental and incipient oceanic crust, preserves vital records of lithospheric extension and rupture, crucial for reconstructing Antarctica's ancient configuration. Extensive ice cover and extreme environments restrict the obtainable geological and ground‐based data ...

Geomagnetic Dipole Strength During the Cretaceous Normal Superchron Recorded by Baked Sediments From Hainan (SE Asia)

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract The Cretaceous Normal Superchron constitutes an enigmatic ∼37‐Myr interval of stable polarity in the history of the Earth's magnetic field. The strength of the geomagnetic dipole moment during this interval is controversial, with absolute paleointensity determinations on crystallized volcanic rocks, volcanic glasses, and silicate crystals ...

1.38 Ga Four‐Layer Tuff Marker Horizon in North China black Shales as a Chronostratigraphic Boundary for the Pre‐Ediacaran Geological Timescale

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Boundaries in the Phanerozoic chronostratigraphic scale are mainly precisely defined and dated, and many correspond to environmental catastrophes induced by the emplacement of LIPs. The pre‐Ediacaran geological timescale is currently subdivided by approximate absolute ages.
