Traveltime Tomography to Unravel the Chalk Group Structures at the Gassum CCS Site, Denmark

open access: yesGeophysical Prospecting, Volume 74, Issue 3, March 2026.
ABSTRACT In carbon capture and storage (CCS) projects, it is important to investigate the seal properties, which often include the shallower part of the investigated area. Reflection seismic data in most of the Danish Basin appear less strong and coherent in the top 500 m, and hence reflectivity alone cannot be used to study the integrity of these ...

Potential for stratiform base-metal sulphides in SW England [PDF]

open access: yes, 2004
The British Geological Survey (BGS) has recently re-evaluated the potential for stratiform base-metal sulphide mineralisation in Devon and east Cornwall (Rollin et al., 2001) (Figure 1). On the basis of their stratigraphy and tectonic setting the Lower

Geophysical investigation of landslides : a review [PDF]

open access: yes, 2007
International audienceIn the last two decades, shallow geophysics has considerably evolved with the emergence of 2D spatial imaging, then 3D spatial imaging and now 4D time and space imaging.

Holocene climate oscillations, seismotectonic events and human–environmental interactions reconstructed from the Giannades palaeolake on Corfu (Eastern Mediterranean, Greece)

open access: yesJournal of Quaternary Science, Volume 41, Issue 2, Page 316-332, February 2026.
ABSTRACT The Mediterranean is particularly sensitive to rapid climate changes (RCCs) during the Holocene. An increasing number of natural climate archives revealed that socio‐economic developments were influenced by such RCCs since the Palaeolithic. However, multi‐millennial and high‐resolution archives are still rare and often located in mountainous ...

Survey and Sequence Strategies for Full‐3D Electrical Resistivity Tomography in Archaeological Sites: A Case Study on a Domus of the Roman Town of Augusta Bagiennorum (NW Italy)

open access: yesArchaeological Prospection, Volume 33, Issue 1, Page 87-107, January/March 2026.
ABSTRACT Preliminary geophysical investigations are a cost‐effective and efficient way to screen archaeological sites and locate buried structures. Ground‐penetrating radar (GPR) is one of the most widely used methods for archaeological prospection, but in some sites, it cannot be employed effectively due to the presence of clay or other electrically ...

Surface wave analysis for building near surface velocity models: established approaches and new perspectives [PDF]

open access: yes, 2010
Today, surface-wave analysis is widely adopted for building near-surface S-wave velocity models. The surface-wave method is under continuous and rapid evolution, also thanks to the lively scientific debate among different disciplines, and interest in the

Upper Cretaceous Seismic Stratigraphy and Magma‐Enhanced Petroleum System of the Offshore Indus Basin

open access: yesBasin Research, Volume 38, Issue 1, January–February 2026.
Seismic data reveals Cretaceous stratigraphy and hydrocarbon potential beneath volcanic rocks in Offshore Indus Basin, where magmatic intrusions enhanced source rock maturation and hydrocarbon generation by 8%–18% during favourable timing coinciding with Deccan volcanism.

Imaging of a fluid injection process using geophysical data - A didactic example [PDF]

open access: yes, 2020
In many subsurface industrial applications, fluids are injected into or withdrawn from a geologic formation. It is of practical interest to quantify precisely where, when, and by how much the injected fluid alters the state of the subsurface.
