Linking Cenozoic Magmatism in the North‐Central Tibetan Plateau With Plateau Growth

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.
Abstract Accurate reconstruction of paleo‐crustal and lithospheric thicknesses is crucial for understanding the deep geodynamic processes driving the uplift and growth of the Tibetan Plateau (TP) and their association with Cenozoic magmatism. We reconstruct the Cenozoic crustal thickness evolution of the north‐central TP using a machine learning model ...

A New Approach to Imaging Deep Crustal Structures: Implications for the Crustal Architecture of Southeast Australia's Passive Margin

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 4, April 2025.
Abstract In the passive margin of southeast Australia, a mosaic of tectonic structures of the Otway Basin records the protracted Cretaceous to Eocene break‐up evolution of Australia and Antarctica. Here, we use an innovative approach that combines Euler deconvolution and DBSCAN clustering of global magnetic data and drill‐hole‐constrained ...

The interrelationship among exercise intensity, endothelial function, and ghrelin in healthy humans

open access: yesPhysiological Reports, Volume 13, Issue 7, April 2025.
Abstract Ghrelin circulates in acylated (AG) and deacylated (DAG) isoforms and both may impact endothelial function (EF). Although acute exercise has been shown to modulate ghrelin levels and EF, data on the impact of exercise intensity on these parameters are scarce.

Resolving Mantle Composition Suggests a Warmer East Antarctic Mantle

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.
Abstract Antarctica's geothermal heat flow and its glacial isostatic adjustment response are critical to understand ice sheet stability. These demand a knowledge of the temperature of the Antarctic lithosphere, but challenges remain in resolving mantle thermomechanical properties.
