Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

New contributions to the Early Pliocene geomagnetic field strength: Case study of southern Caucasus volcanics [PDF]
Geofísica Internacional, 2000 We carried out a Thellier paleointensity study on a ~ 3.8 My Pliocene lava flow succession from Georgia (southern Caucasus). Previous paleomagnetic studies on this succession revealed that eight consecutive lava flows record a reverse polarity direction ...

Geochemistry, Geophysics, Geosystems, 2014 Eruptive timing in mid‐ocean ridge systems is relatively poorly constrained, despite being an important variable in our understanding of many mid‐ocean ridge processes, including volcanic construction; magma recharge, flux, and storage; and the stability

Timing of volcanism along the northern East Pacific Rise based on paleointensity experiments on basaltic glasses [PDF]
, 2004 Samples from two adjacent and contrasting ridge segments along the East Pacific Rise were measured for their magnetic paleointensity in order to further explore the possibilities of dating very young volcanic samples using secular variations in the Earth'

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We present a new method for paleomagnetic investigations, polarized neutron imaging, a non‐destructive magnetic imaging technique benefiting from the high penetration depth and spin of the neutron allowing spatial characterization of the magnetic field within a sample.

Paleomagnetism. Solar nebula magnetic fields recorded in the Semarkona meteorite. [PDF]
, 2014 Magnetic fields are proposed to have played a critical role in some of the most enigmatic processes of planetary formation by mediating the rapid accretion of disk material onto the central star and the formation of the first solids.

Application of the pseudo-Thellier technique to a paleomagnetic record from lake El Trébol (Patagonia, Argentina) [PDF]
Geofísica Internacional, 2008 The pseudo-Thellier technique was applied to obtain relative paleointensity determinations using a sediment core from Lake El Trébol (Patagonia, Argentina).

, 2019 Metallic microstructures in slowly-cooled iron-rich meteorites reflect the thermal and magnetic histories of their parent planetesimals. Of particular interest is the cloudy zone, a nanoscale intergrowth of Ni-rich islands within a Ni-poor matrix that ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...
