Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

Sedimentology, EarlyView.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Evaluation of porosity, permeability, and reservoir quality of the Asmari Formation using sedimentary facies and diagenesis data in the Ahvaz oil field [PDF]

Journal of Stratigraphy and Sedimentology Researches
The Asmari Formation, the Oligo–Miocene in age, has been deposited in the Dezful Embayment and other parts of the Zagros Basin. In the Ahvaz oil field, this formation is mostly composed of limestones, dolomites, marls, and sandstones.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Re-evaluation of the Triassic sequence in the subsurface of the Little Plain Basin Hungary: A case study from the Győrszemere-2 well [PDF]

, 2014
The Little Plain Basin is one of the largest units in the Pannonian Basin System. Its continuation in Slovakia is called the Danube Basin. The Little Plain Basin is one of the most underexplored areas in Hungary.

Multidisciplinary approach to revisit the state of activity of a deep‐seated gravitational slope deformation in the frame of the Quaternary geomorphological evolution of the Central Apennines (Italy)

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Abstract Evaluating the state of activity of Deep‐Seated Gravitational Slope Deformation (DSGSD) is a challenge that requires multidisciplinary analytical approaches. This research focuses on the slope‐scale gravitational process, framing the role of the Quaternary morphodynamics of a river valley where multiple DSGSDs coexist, to reconstruct the ...

A novel population of composite mounds: their initiation, growth and demise. San Emiliano Formation, Cantabrian Mountains, Spain [PDF]

, 2018
Purpose: Mounds from the Pennsylvanian aged San Emiliano Formation (Cantabrian Mountains, Spain) are commonly well exposed. These mounds range from 2 to 50 m in height and are observed to be primary geological features.

The Messinian Salinity Crisis Between Italy and Albania: The Peri‐Adriatic Depression and Southern Adriatic Basin Records

Basin Research, Volume 38, Issue 2, March/April 2026.
Basin‐scale correlation of Messinian salinity crisis (MSC) deposits across the Apennine–Albanide foreland basin system integrating outcrop and subsurface data. ABSTRACT We reconstructed the geological evolution of the Albanides during the Messinian salinity crisis (MSC), based on the integration of outcrop and subsurface data from both onshore (peri ...
