The Kongquehe Sag, located in the western Lop Nur, has abundant pore subsurface brine. In order to study source and origin, we tested analyzed hydrochemical composition stable isotopes of findings reveal that brine exhibits a moderate low degree mineralization, with values ranging from 50.50 g/L 91.14 g/L. isotope compositions unconfined confined waters are different, mean δD being −8.00‰ −51.75‰ δ18O 10.08‰ −6.01‰. These indicative an intense evaporative environment prevalent Sag area. Furthermore, 87Sr/86Sr ratios vary between 0.710642 0.710837, δ34S range 9.2 10.7. data suggest long-term evolution sulfur substances, predominantly through dissolution sedimentation processes, minimal influence redox reactions. garnered this research not only offer novel perspective insights gained into characteristics signatures brines area but also enriches theoretical framework concerning origin brines, potentially informing future exploration strategies.

Study region: Tabu Basin is located on a typical-deserted steppe in Inner Mongolia, China and plays significant role maintaining ecological stability of northern China. focus: Among rivers worldwide, 51–60 % cease to flow for at least one day annually, especially arid semiarid areas. Understanding interactions between intermittent (IRs) groundwater (GW) crucial protecting water resources sustaining balance. A comprehensive framework was developed analyze these interactions. New hydrological insights the Unlike previous studies, this study considered seasonal differences hydrochemical isotopic compositions IR GW, as well intensive influence evaporation. Multitemporal datasets were employed IR–GW interaction across spatial, temporal, profiling scales. Hydrochemical evidence analysis indicated input meltwater with depleted signatures GW recharge IR.

This study investigates the Batha endorheic basin in Chad, situated east of Lake Chad arid to semi-arid Sahelian zone. region has not yet undergone comprehensive geological and hydrogeological studies. More broadly, transition zone between climates been minimally explored. research aims evaluate resources dynamics this multi-layered system using a combined geology-hydrogeology-hydrochemistry-isotopes approach. The multilayer includes sedimentary layers (Quaternary, Pliocene, Eocene) over crystalline basement. A piezometric investigation shows general SE–NW groundwater, indicating an interconnection all layers. Hydrochemical analyses identifies four main facies (calcium-bicarbonate, sodium-bicarbonate, sulphate-sodium, mixed), primarily controlled by water–rock interaction with secondary influences from base-exchange evaporation. Saturation indices indicate that these waters are close equilibrium calcite-Mg phases, gaylussite gypsum. Stable isotopes (oxygen-18 deuterium) categorize groundwater into three groups: ancient water, recent older meteoric water mixtures affected evaporation, more heavily impacted Tritium contents reveal current rainwater, modern sub-modern water. These results ionic isotopic differentiations cannot be strictly linked specific layers, confirming interconnected nature system. observed heterogeneity is mainly influenced lithological climatic variations. study, though still limited, enhances significantly understanding basin’s functioning supports rational exploitation its vital for area’s development. Future investigations complete present highlighted.
