An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, Volume 68, Issue 4, Page 804-810, August 2026.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...

Comparative Gas‐Brine Relative Permeability of H2, N2, and CO2 Under Subsurface Storage Conditions

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Gas‐brine relative permeability controls subsurface gas storage, including underground hydrogen and CO2 storage. Here, we measure steady‐state gas‐brine relative permeabilities for H2, N2, and CO2 in a sandstone core at 0.1–6 MPa under identical conditions.

Effects of Pore Fluid Properties on Dynamic Slip in Sandstone‐Derived Fault Gouges From the Groningen Gas Reservoir

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...

Exsolution, Evolution, and Hysteresis of CO2 Nanobubbles in Water‐Saturated Sandstone

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Understanding CO2 nanobubble formation in water‐saturated sandstone is critical for understanding fluid behavior in CO2 storage systems. Here, CO2 exsolution from an aqueous phase in a sandstone was investigated using small‐angle neutron scattering at 50°C during cyclic depressurization from 12 to 0.7 MPa.

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, Volume 61, Issue 7, Page 1976-2001, July 2026.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Assessing unfrozen water content using capacitance sensors in frozen soils: A new physics‐based conversion curve

Vadose Zone Journal, Volume 25, Issue 4, July/August 2026.
Abstract One of the most widely used techniques to measure the unfrozen water content of cryotic soils is to monitor their apparent dielectric permittivity. Paired with an empirical calibration equation or a dielectric mixing model, this measurement, εeff$\varepsilon _{\text{eff}}$, gives an estimate of unfrozen water content in soils.

Geophysical Investigation of Geothermal Potential in Southern Thailand: Insights From GGMplus Gravity

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Southern Thailand hosts numerous low‐ to medium‐enthalpy geothermal manifestations in a non‐volcanic setting. This study investigates the geothermal potential of the region through the integration of satellite‐derived gravity data and geological observations.

The Geologic History of the Chehalis Forearc Basin, Washington State, USA

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The Chehalis basin is located between the Cascade arc and the Coast Range in southwest Washington State. It consists of sedimentary and volcanic rocks deposited throughout the Cenozoic and is underlain by the Siletzia terrane, a thick, large igneous province accreted in the Eocene.

Multiphysics Monitoring of Capillary, Electrical, and Elastic Responses During Drainage and Imbibition at Reservoir Conditions

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Capillary pressure‐saturation relationships are crucial for geo‐energy recovery, and increasingly, for environmental applications. However, for reservoir‐relevant pressure and temperature conditions, only limited data sets are available from special core analysis in laboratory (SCAL) studies.
