Rupture Cascade Initiated by Wastewater Disposal: Nucleation and Domino Effect of Canada's Largest Induced Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.

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]

open access: yesInternational 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).

Silicification and dolomitization of anhydrite nodules in argillaceous terrestrial deposits: an example of meteoric-dominated diagenesis from the Triassic of central Spain [PDF]

open access: yes, 2002
Cauliflower-shaped nodules are widespread in a single red mudstone bed in the Buntsandstein (Triassic) facies of the Iberian Range. They consist mostly of quartz, dolomite and calcite, but other minerals, such as barite, kaolinite and iron ...

Hydrothermal dolomitization of basinal deposits controlled by a synsedimentary fault system in Triassic extensional setting, Hungary [PDF]

open access: yes, 2016
Dolomitization of relatively thick carbonate successions occurs via an effective fluid circulation mechanism, since the replacement process requires a large amount of Mg-rich fluid interacting with the CaCO3 precursor.

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

open access: yesGeoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

On the peritidal cycles and their diagenetic evolution in the Lower Jurassic carbonates of the Calcare Massiccio Formation (Central Apennines) [PDF]

open access: yes, 2015
This paper shows the environmental changes and high-frequency cyclicity recorded by Lower Jurassic shallow- water carbonates known as the Calcare Massiccio Formation which crop out in the central Apennines of Italy.

Unusual biota and palynofacies of a Lower Devonian intermontane basin saline lake–playa mudflat ecosystem

open access: yesPapers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Strathpeffer–Struie Lower Devonian LORS (Lower Old Red Sandstone) deposits of the Northern Highlands of Scotland contain the decidedly unusual ‘foetid beds’. These are interpreted as being deposited in a highly saline sulphate lake and associated playa mudflat, which developed in an intermontane basin in the Caledonian Mountains of ...

Dolomitization of Triassic microbial mat deposits (Hungary): Origin of microcrystalline dolomite [PDF]

open access: yes, 2015
Dolomite most commonly forms via replacement of precursor carbonate minerals. For this reason, diagnosing primarily precipitated organogenic dolomite in microbial mat deposits from the rock record is not straightforward, even though the deposits exhibit ...

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
