Exploring the 3D Gravity Inversion Problem Using a Compact Hybrid Transformer‐Based Deep Learning Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract The three‐dimensional (3D) gravity inversion problem is the process of delineating the volumetric mass distributions from the surface gravity anomalies. Recently, many innovative Convolutional Neural Network (CNN) based algorithms have found some success in reduction of computation costs and delineation of sharper boundaries of causative ...

Input Selection in Conventional Supervised Machine Learning in Geophysical‐Geological Mapping Applications: Improving Analytical Transparency and Model Parsimony

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract When conventional supervised machine learning (ML), including decision trees, support vector machines (SVMs), and k‐nearest neighbors (KNN), is applied to geological problems involving complex data sets, it is necessary to select a subset of raw or pre‐processed data types that will be used as input to the ML model.

Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective contributions remain unconstrained.

Velocity estimation in GPR data based on diffraction analysis: Methodology and application to Antarctic firn

Near Surface Geophysics, Volume 24, Issue 2, Page 170-186, April 2026.
Abstract This study presents a methodological framework for estimating electromagnetic wave velocities in ground‐penetrating radar (GPR) data based exclusively on the analysis of diffractions. The approach integrates diffraction separation using the plane wave destruction algorithm and subsequent velocity refinement through the residual diffraction ...

Grounding‐Zone Wedge Formation and Effects on Ice‐Stream Retreat and Stability

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Ice streams deposit sediment at their grounding lines, where ice reaches flotation. Grounding Zone Wedge (GZW) deposits indicate stillstands in past grounding‐line retreat, and are thought to stabilize grounding lines by reducing local water depth, restricting ice flow. However, the mechanisms of GZW growth are uncertain, as are the effects of
