Unstructured Grid Based Joint Inversion of DC Resistivity and Gravity Data: Adaptive FCM Assisted Model Coupling and Quantitative Similarity Analysis

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Many geophysical studies have highlighted the limitations of relying on a single geophysical data set to understand subsurface conditions. Often, individual inversions yield inconsistent geologic models. To address this issue, this study integrates direct current (DC) resistivity and gravity data within a joint inversion (JI) framework.

An Improved Chemical Extraction Procedure for the Sr Isotope Analysis of Liquid Agrifood Samples Applied to Authenticating the Origin of Maple Syrups in Quebec (Canada)

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 16, 30 August 2025.
ABSTRACT Rationale We describe a new simplified sample preparation technique, based on dual chromatography for the analysis of 87Sr/86Sr in liquid agri‐food samples. We applied this approach for authenticating the origin of maple syrup products in Quebec, characterizing the 87Sr/86Sr of soil profiles from geologically distinct maple groves, including ...

Receiver Function Imaging of the Mantle Transition Zone Beneath the East Sayan Mountains and Adjacent Area in Central Asia: Implications for Lithospheric Drip and Intraplate Cenozoic Volcanism

open access: yesGeophysical Research Letters, Volume 52, Issue 15, 16 August 2025.
Abstract To provide constraints on the formation mechanisms of intracontinental volcanisms and intriguing lithospheric thickness variations in the East Sayan Mountains and surrounding areas, we stack P‐to‐s receiver functions to image the 410‐km and 660‐km discontinuities.

Duration and Geochemical Evolution of Triassic and Jurassic Magmatism Along the Eastern North American Margin

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 8, August 2025.
Abstract Our understanding of the impact of melt generation and the interplay between magmatism and mechanical stretching during progressive rifting leading to seafloor spreading remains rudimentary. The Eastern North American Margin (ENAM) provides an excellent location to study the influence of rift magmatism on continental break‐up considering the ...
