Uranium Addition and Loss in Serpentinites: The Potential Role of Iron Oxides

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Fluid‐mobile uranium serves as a tracer for water‐rock alteration in serpentinized mantle rocks, which constitute an important uranium reservoir. However, the mechanism for uranium addition, where uranium is hosted, and the stability of the uranium enriched material during subduction is not settled.

Quantitative Provenance Analysis of the Yangtze and Yellow River Sediments Through Detrital Zircon U‐Pb Geochronology Using an XGBoost Machine Learning Algorithm

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Over the past two decades, a large number of zircon U‐Pb ages from the Yangtze and Yellow River Basins have been published, yet distinguishing the sources of sediment between these regions remains challenging. Issues related to sampling, analytical methods, and biases complicate the interpretation of detrital zircon geochronology.

Structural Data and Thermometry Indicate That the Tso Morari UHP Nappe (Indian Himalaya) Was Emplaced as a Large‐Scale, Structurally Coherent Sheet

Tectonics, Volume 44, Issue 9, September 2025.
Abstract Ultrahigh‐pressure (UHP) nappes provide important opportunities to investigate the processes that exhume rocks from upper mantle depths. Here, we investigate the UHP Tso Morari nappe (TMN) in the Indian Himalaya to test competing models for the construction of UHP nappes via detachment of single, structurally coherent sheets, accretion of ...

Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen

Tectonics, Volume 44, Issue 9, September 2025.
Abstract The Himalayan‐Tibetan orogen formed via the ongoing collision of India and Asia. Its colossal elevations stem from buoyant crustal roots that doubled in thickness during continental collision, widely believed to result from Indian crust under‐thrusting its Asian counterpart and Asian crustal thickening. However, a single crustal layer of up to
