Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Hydropeaking Catalyzes Redox Reactions in Impacted Aquifers: A First Field Evidence

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Hydropeaking indicates the sudden and frequent fluctuation of river stage caused by the operation of hydropower plants. This river alteration affects numerous physical, chemical, biological, and ecohydrological processes in surface water bodies.

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.
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

Geochemical and Isotopic Evidence of Groundwater Salinization Processes in El Dabaa Area, Northwestern Coast, Egypt

Geosciences, 2018
El Dabaa city is located along the northwestern coast ridge zone of Egypt, where the groundwater is the major water source for drinking, domestic, and agricultural purposes. The groundwater salinity increased over the last decades, therefore, geochemical

Delineation of Flow Components in a Tropical Region With Carbonate Rocks of Southeastern Mexico

Hydrological Processes, Volume 40, Issue 9, September 2026.
Hydrochemistry and statistical methods help to delimit the flow components in carbonate rocks with marine intrusion. ABSTRACT This study analyses groundwater flow systems in a tropical karst aquifer of the Yucatán Peninsula, Mexico, where population growth and tourism are concerns due to increasing urbanisation.

Short‐term soil responses and site conditions to inverted mounding on peatland linear features in Alberta, Canada

Restoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction Seismic lines represent one of the most extensive and persistent anthropogenic disturbances in boreal peatlands, limiting forest regeneration and altering key ecosystem functions. Inverted mounding is increasingly applied to elevate planting microsites above shallow water tables, yet evidence on short‐ to medium‐term biophysical ...
