Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

On the topographic effects by Stokes’ formula

open access: yesJournal of Geodetic Science, 2014
Traditional gravimetric geoid determination relieson Stokes’ formula with removal and restoration of thetopographic effects. It is shown that this solution is in errorof the order of the quasigeoid-to-geoid difference, which ismainly due to incomplete ...

Anatomy of Rift‐Segmenting Transfer Zones: New Insights From the 3D Integrated Interpretation of the Southeastern Sector of the Basque‐Cantabrian Basin and the Pamplona Fault (Pyrenees, N Spain)

open access: yesBasin Research, Volume 38, Issue 1, January–February 2026.
An updated view of the southern part of the Cantabrian‐Pyrenean junction through a 3D geological model shows the first conclusive evidence for the ~65 km‐wide diffuse Pamplona transfer zone linking the Basque‐Cantabrian and Mauleon segments of the Pyrenean rift. This transfer zone also affected the style of deformation and configuration of the Pyrenean

Application of High‐Precision Microgravity Detection Technology in the Exploration of Ultradeep Gas Reservoirs in the Middle Part of the Southern Margin of Junggar Basin

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
This study is aimed at identifying the ultradeep gas reservoir structure and gas‐rich areas in the middle section of the southern margin of the Junggar Basin. Based on high‐precision microgravity data collected from the complex terrain areas of Huxi and Tudong in the middle section of the southern margin of the Junggar Basin, residual gravity anomalies

Formation of Caloris Basin's Positive Mass Anomaly by Thermal Contraction During Its Postimpact Evolution

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Caloris basin preserves a record of Mercury's volcanic and tectonic activity, including the long‐wavelength warping of its surface in the north‐south direction. As Mercury's largest mascon basin, identifying Caloris' configuration prior to volcanic infilling is a key step in determining the series of events that led to its current state. Here,

A Novel Iterative Stable Algorithm for Global Moho Modeling in the Spherical Harmonic Domain

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The Mohorovičić discontinuity (Moho) marks the boundary between Earth's crust and the underlying mantle, serving as a critical interface for understanding Earth's structure, composition, and geodynamic processes. This study introduces a novel iterative and stable algorithm for global Moho depth inversion.

New Bouguer Anomaly Map for the Territory of the Slovenia

open access: yesRemote Sensing, 2021
The existing Bouguer anomaly map, which covers the territory of the Republic of Slovenia is a few decades old. Since then, quite a few new gravimetric measurements (data) for the territory of Slovenia as well as high quality digital terrain models that ...
