Decadal‐Scale In Situ Scanning of a Stalagmite From Southwest China Reveals Blake Geomagnetic Excursion Structure

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We present a decadal‐scale paleomagnetic analysis of a stalagmite collected from Shuixi Cave, southwest China, spanning 89−123 ka. Our findings include: (a) Magnetite is the dominant magnetic mineral, and paleomagnetic directions can be obtained via demagnetization; (b) Magnetic scanning at 0.1‐mm resolution captures key magnetic features ...

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

open access: yesGeophysical 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.
