The Magnetic Fingerprint of Pulsed Granite Magma Emplacement and Alteration: Slaufrudalur Pluton, Iceland

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Magma reservoirs typically form through the incremental emplacement of smaller magma pulses over extended timescales. Pulsed reservoir growth significantly impacts a magma body's temperature evolution, chemical differentiation potential, and the probability, scale, and timing of volcanic eruptions.

Multi‐Stage Crustal Thickening, Surface Uplift, and Collision in the Western Himalaya‐Karakoram‐Tibet Orogen Revealed by Chemical Mohometry

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract The Himalaya‐Karakoram‐Tibet (HKT) orogen provides an unrivaled opportunity to study the dynamic linkages between deep and surface processes during collisional orogenesis. However, these efforts are hindered by conflicting interpretations on the number and timing of collisional events, and the timing of crustal thickening and associated ...

The Role of Continental Alkaline Magmatism in Mantle Carbon Outflux Constrained by a Machine Learning Analysis of Zircon

Geophysical Research Letters
Continental alkaline magmatism has been suggested to play a significant role in releasing deep mantle carbon into the atmosphere, which can greatly impact the global climate.

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.

Disentangling Partial Melting and Crustal Recycling Signatures in Ocean Island Basalts With Multivariate Statistics

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Ocean island basalts (OIB) provide valuable constraints on mass exchange between the mantle and crust. When appropriate compositional data transformations are applied, multivariate analyses of OIB compositions can be used to infer mantle source heterogeneity and elucidate its driving processes.

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.
