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.

An Ecological Perspective on Dolomite Formation in Great Salt Lake, Utah

Frontiers in Earth Science, 2020
Protodolomite was detected in sediments from Great Salt Lake (GSL), Utah, United States, that have no history of elevated temperature or pressure, conditions that are thought to promote dolomitization of sedimentary carbonates. Protodolomite was abundant

Cambrian small shelly fossils from North Greenland (eastern Laurentia; Series 2, Stage 4) with regional and global correlations

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Cambrian Series 2 represents a key interval for documenting the evolution and diversification of early biomineralized skeletal animals. In this interval, small shelly fossils (SSF) provide an essential archive for regional biostratigraphy and intercontinental correlation.

Correlative X‐Ray and Neutron Tomography of Microbial Biosignatures: Perspectives for Mars Sample Return

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.

Structural Evolution of a Polyphase Salt‐Tectonic System From Syn‐Rift Extension to Syn‐Orogenic Deformation in the Middle Atlas (Oum Er Rbia Region, Morocco)

Tectonics, Volume 45, Issue 7, July 2026.
Abstract Salt tectonics has received little attention in the Middle Atlas, despite the widespread occurrence of Triassic evaporites and their potential to exert first‐order control on basin architecture and deformation. This study presents the first integrated analysis of polyphase salt tectonics in the Middle Atlas, focusing on the Oum Er‐Rbia sector,

The Global Contribution of Individual Submarine Groundwater Discharge Components to the Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Saline submarine groundwater discharge (SSGD) contributes to ocean chemistry through water‐rock interactions as seawater circulates in coastal aquifers. Its components, driven by different mechanisms, exhibit varying residence times and degrees of chemical alteration, so constraining solute fluxes requires quantifying each component.

The Impact of Diagenesis and Dolomitization on the Reservoir Potential of Middle Jurassic Samana Suk Formation from Khanpur Dam Section Hazara Basin, Khyber Pakhtunkhwa Pakistan [PDF]

International Journal of Economic and Environment Geology, 2017
Detailed study of the Samana Suk Formation has been carried out from the Khanpur Dam Section. Two lithological units have been identified in the studied section, limestone and dolomite (60% and 40% respectively).

Quantification of the Eocene–Oligocene transition in the Zagros Foreland Basin: Palaeogeographic control on sequence architecture and tectonic signal preservation

The Depositional Record, Volume 12, Issue 3, June 2026.
New bio‐sequence framework for the Eocene–Oligocene transition in Zagros. Geochemical data validate basin depth control on SB1 vs. SB2 boundaries. SEM‐EDS analyses confirm subaerial exposure versus continuous deposition. Sensitivity analysis quantifies sub‐10% uncertainty in stratigraphic interpretations. Resolves the Pyrenean orogeny's variable impact

Transient Porosity During Fluid‐Mineral Interaction. Part 1: In Situ 4D Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Fluid‐induced mineral replacement reactions play a key role in controlling porosity generation and permeability evolution in geologic systems. However, the dynamic feedback between pore structure development and fluid transport remains poorly quantified. This study investigates the spatiotemporal evolution of reaction‐induced pore space in the

Transient Porosity During Fluid‐Mineral Interaction, Part 2: Reconstruction Using Generative AI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Quantifying fluid–rock interactions within the lithosphere is vital for both geological processes and applications such as CO2 ${\text{CO}}_{2}$ storage and geothermal energy development. Mineral replacement reactions generate transient pore networks that enhance fluid flow, yet many pores become isolated once reactions are completed, reducing
