Dolomitization of the Lower Part of the Sargelu Formation, Northeastern Iraq

Tikrit Journal of Pure Science
The prominent characteristic of the lower part of the Sargelu Formation of the Middle Jurassic is the occurrence of destructive dolomitization. This dolomitized unit, cropped out in the high folded and Imbricated zones in Northern Iraq, is situated in ...

Ferroan Dolomitization by Seawater Interaction with Mafic Igneous Dikes and Carbonate Host Rock at the Latemar Platform, Dolomites, Italy: Numerical Modeling of Spatial, Temporal, and Temperature Data

Geofluids, 2017
Numerous publications address the petrogenesis of the partially dolomitized Latemar carbonate platform, Italy. A common factor is interpretation of geochemical data in terms of heating via regional igneous activity that provided kinetically favorable ...

Dolomitization mechanism of Pila Spi formation (middle- late eocene) in the high folded zone, Northern Iraq

Kuwait Journal of Science, 2023
Petrographic analysis and geochemistry of the Pila Spi Formation (Middle-late Eocene) were investigated from two outcrop sections (Gali-Zakho and Shaqlawa), within the High Folded Zone, northern Iraq.

Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

The Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...

The endo-upwelling concept : from geothermal convection to reef construction [PDF]

, 1993
Les analyses d'eaux interstitielles faites dans les atolls de Mururoa et de Tikehau (Tuamotu) montrent qu'elles sont riches en sels nutritifs dissous. Le marqueur conservatif salinité indique une origine océanique profonde (eau antarticque intermédiaire)

The Permian–Triassic transition in Türkiye: New insights and 3D outcrop models for accessible, reproducible and sustainable fieldwork

The Depositional Record, Volume 12, Issue 2, April 2026.
We studied the Permian–Triassic successions of south‐western Türkiye at five locations, synthesised sedimentological and palaeontological data, putting it into a consistent stratigraphic framework and incorporating 3D digital outcrop models. Abstract The Permian–Triassic transition is characterised by major environmental changes and the largest known ...

Mg isotope fractionation during microbial dolomite formation in the Khor Al‐Adaid sabkha, Qatar

The Depositional Record, Volume 12, Issue 2, April 2026.
Modern sabkha sediments from southern Qatar show ca. 1‰ Ca isotope fractionation between pore water, organic matter and dolomite, supporting microbial mediation. In contrast, minimal Mg isotope fractionation and inorganic‐like dolomite δ26Mg indicate that microbial influence is indirect, expressed through subtle pore water shifts driven by Mg ...

Characteristics of Lacustrine Diamictite and Analysis of Diagenetic Reservoir Facies in the Neogene Lower Youshashan Formation in the Dafengshan Tectonic Belt in the Qaidam Basin

Energy Science &Engineering, Volume 14, Issue 4, Page 1976-1989, April 2026.
Based on field outcrop data, core descriptions, comprehensive thin section data (plain, cast, and fluorescent), scanning electron microscopy, whole rock analysis via X‐ray diffraction, physical property tests, element logging, core recording, and oil pilot tests, we propose utilizing a mature and practical three component classification method for ...

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.
