Constraints on carbonate diagenetic fluid properties by microzone in situ analysis of carbon and oxygen isotopes: a case study of Cambrian-Ordovician, Tarim Basin

Shiyou shiyan dizhi, 2023
As an important technological measure to uncover complex sedimentary-diagenetic process, microzone in situ geochemical analysis has drawn more and more attention along with improving analytical and test levels.

Genesis of self-organized zebra textures in burial dolomites : displacive veins, induced stress, and dolomitization [PDF]

, 2006
The dolomite veins making up rhythmites common in burial dolomites are not cement infillings of supposed cavities, as in the prevailing view, but are instead displacive veins, veins that pushed aside the host dolostone as they grew.

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 ...

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 ...

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.

Two‐Stage Dolomite Formation in Carbonate Platforms Revealed by Carbonate Clumped Isotope Thermometry

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The “dolomite problem” refers to the scarcity of dolomite in Cenozoic marine environments compared with its abundance in earlier strata. This discrepancy has been attributed to changes in marine environments or to insufficient thermal maturity required for dolomite formation.

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?

The Depositional Record, Volume 12, Issue 1, February 2026.
This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.

Interpretation of the origin of massive replacive dolomite within atolls and submerged carbonate platforms : strontium isotopic signature ODP hole 866A, resolution Guyot, mid-Pacific mountains [PDF]

, 1996
Endo-upwelling is a geothermally driven convective process operating within the upper part of the volcanic foundation and overlying carbonate pile, in atolls and guyots.

Carbonate sedimentology: An evolved discipline

The Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.
