Advances in understanding natural groundwater quality controls in coastal aquifers [PDF]

, 2005
Groundwater quality in coastal aquifers is largely influenced by the interaction between the sea and the bordering aquifer systems. This interaction can result in freshening of saline aquifers or salinization of fresh water bodies.

Sedimentary dolomite in Western Australia and the dolomite problem: Genesis of channel and playa uranium deposits

Sedimentology, Volume 71, Issue 7, Page 2248-2289, December 2024.
ABSTRACT Quaternary to Recent sedimentary dolomite in groundwater calcrete and saltmarsh sediments of Lake Way and Lake Maitland, Western Australia, provide new information about the formation of low‐temperature dolomite. Dolomite can form through numerous pathways depending on the depositional and diagenetic environment.

Phreatic overgrowths on speleothems (POS) from the Mallorca caves: Morphology, mineralogy, and crystal fabric classification

Earth Surface Processes and Landforms, Volume 49, Issue 13, Page 4289-4309, October 2024.
An important number of POS (tracers of past seawater levels) sampled from the coastal caves of Mallorca (Spain) have been studied. A systematization has been done according to their morphology, crystal fabric and mineralogy and to their position above or below the current sea level.

CONTRIBUTION TO THE GENESIS OF THERMAL WATER OF THE NORTH-EAST PERIMETER OF THE ZENICA-SARAJEVO BASIN, BOSNIA AND HERZEGOVINA

Rudarsko-geološko-naftni Zbornik, 2017
The phenomena of thermal waters in the northeastern periphery of the Zenica-Sarajevo basin is caused by the geological structure, structural-tectonic and hydrogeological characteristics of the terrain.

Hybrid off-river augmentation system as an alternative raw water resource: the hydrogeochemistry of abandoned mining ponds [PDF]

, 2016
The use of water from abandoned mining ponds under a hybrid off-river augmentation system (HORAS) has been initiated as an alternative water resource for raw water. However, it raises the questions over the safety of the use of such waters. In this study,

Antecedent Hydrologic Conditions Reflected in Stream Lithium Isotope Ratios During Storms

Geophysical Research Letters, Volume 51, Issue 17, 16 September 2024.
Abstract Antecedent hydrological conditions are recorded through the evolution of dissolved lithium isotope signatures (δ7 ${\delta }^{7}$Li) by juxtaposing two storm events in an upland watershed subject to a Mediterranean climate. Discharge and δ7 ${\delta }^{7}$Li are negatively correlated in both events, but mean δ7 ${\delta }^{7}$Li ratios and ...

Faulting patterns in the Lower Yarmouk Gorge potentially influence groundwater flow paths [PDF]

, 2019
Recent studies investigating groundwater parameters, e.g., heads, chemical composition, and heat transfer, argued that groundwater flow paths in the Lower Yarmouk Gorge (LYG) area are controlled by geological features such as faults or dikes.
