Crustal Flow‐Driven Plateau Growth and Expansion Front in NE Tibet: Insights From High‐Resolution Attenuation Tomography With High‐Density ChinArray Lg Data

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Connecting the Atlantic Meridional Overturning Circulation to the Southern Ocean Following the Closure of Equatorial Seaways During the Cenozoic

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Global ocean circulation regulates climate and has undergone significant changes over the Cenozoic. Today, the Atlantic Meridional Overturning Circulation (AMOC) is driven by North Atlantic Deep Water (NADW) formation and Southern Ocean upwelling.

Mo Isotopic Records Imply Persistent Ocean Oxygenation in the Deep Southwest Pacific During the Early Cenozoic Warming Period

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract During the early Cenozoic greenhouse period, counterintuitive contractions in tropical Pacific oxygen‐deficient zones have been linked to enhanced deep‐ocean ventilation, yet direct geological evidence remains limited. Here we present molybdenum (Mo) isotopic records from International Ocean Discovery Program Site U1509.
