Sedimentology, EarlyView.ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Characterization of stromatolitic biosignatures after secondary dolomitization
, 2021 The earliest signatures of life preserved in Earth’s rock record are found within fossilized organosedimentary structures called stromatolites. Many of these geologically ancient structures are dolomitized, but the effects of this diagenetic process on ...

Dolomitization of the Lower Part of the Sargelu Formation, Northeastern Iraq
Tikrit Journal of Pure ScienceThe 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 ...

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 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

Multiphase partial dolomitization of Carnian reef limestone
, 2014 Partially dolomitized carbonate successions provide a good opportunity to understand the commonly multistage process of dolomitization. Petrographic methods, fluid inclusion microthermometry and stable isotope measurements were applied to reconstruct the

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

Partial dolomitization of foreslope and toe-of-slope facies of a Carnian carbonate platform, Transdanubian Range, Hungary [PDF]
, 2014 Partial and pervasive dolomitization of foreslope and toe-of-slope deposits of an early Carnian carbonate platform was investigated to understand the process and mechanism of dolomitization.
