Towards a workflow to evaluate geological layering uncertainty on CO2 injection simulation

Applied Computing and Geosciences, 2023
We propose a workflow for updating 3D geological meshed models to test different layering scenarios and to assess their impact on the simulation of CO2 injection.

A Fluvio‐Lacustrine Environment Preserved in the Jezero Crater Inlet Channel, Neretva Vallis, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Martian fluvial valleys provide evidence for the surface flow of liquid water, making them a key target for rover‐based investigations of ancient habitability. The Mars 2020 Perseverance rover spent ∼85 sols exploring the Bright Angel formation, exposed across the floor of Neretva Vallis: the western inlet channel of Jezero crater.

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)

Basin 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

LiDAR mapping of the sedimentary rocks surrounding a salt diapir: a powerful tool to assist landslide identification and structural/depositional sequence analysis (Maestu diapir, N Spain)

Journal of Maps
A new 1:25.000 geological map is presented for a 26 × 22 km quadrangle containing the Maestu salt diapir and its sedimentary country rocks. A new mapping approach was followed to depict the distribution of interpreted late Cretaceous-Paleogene ...

Diagenesis in salt dome roof strata: barite - calcite assemblage in Jebel Madar, Oman [PDF]

, 2017
Halokinesis causes a dynamic structural evolution with the development of faults and fractures, which can act as either preferential fluid pathways or barriers. Reconstructing reactive fluid flow in salt dome settings remains a challenge.

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Tourmaline records the hydrothermal events related to Zn-Pb mineralization around the Murguía diapir (Basque Cantabrian Basin, N Spain)

Geologica Acta, 2019
The chemical composition of tourmaline has been used as a host environment register as well as a potential exploration tool for mineral deposits. In this study, the textural and chemical composition of tourmalines associated with Zn-Pb mineralizations ...

The Gravity Signature of a Large Quaternary Depocentre off Southeastern Canada [PDF]

, 1992
New bathymetry, gravity and Pliocene - Quaternary sediment isopach maps have been compiled and gridded for the Scotian margin. A large positive gravity anomaly exists over the Laurentian Fan, which is the major Pliocene - Quaternary depocentre on the ...

Geophysical Insights Into 3D Crustal Architecture of Jurassic Magmatic Intrusions in the Moroccan Atlas

Earth and Space Science, Volume 12, Issue 12, December 2025.
Abstract Magmatic intrusions in rifted continental margins play a critical role in shaping structural evolution, yet their geometry and emplacement mechanisms remain poorly constrained in salt‐influenced terrains. The Moroccan Central High Atlas, a segment of the Atlas fold‐and‐thrust belt, hosts extensive Middle Jurassic to Early Cretaceous intrusions

Contrastive Analysis of Deep-Water Sedimentary Architectures in Central West African Passive Margin Basins During Late-Stage Continental Drift

Journal of Marine Science and Engineering
The Lower Congo Basin (LCB) and the Niger Delta Basin (NDB), two end-member deep-water systems along the West African passive margin, exhibit contrasting sedimentary architectures despite shared geodynamic settings.
