The objective of this work is to study the chemistry groundwater in messaad plateau which located 300km south capital Algiers. results obtained showed that waters are very strongly mineralized overall, with a predominance calcium sulphate facies and chloride facies. high degree mineralization South South-East part area near Oued Messaad. Principal Component Analysis (PCA) has shown increase mai...

Abstract. At laboratory timescales, rock salt samples with different composition and microstructure show variance in steady-state creep rates, but it is not known if how this manifested at low strain rates corresponding deviatoric stresses. Here, we aim to quantify from the analysis of multilayer folds that developed over geological timescale Ocnele Mari mine Romania. The formation composed 90 ...

Abstract The Qaidam basin in W China is an immense hyperarid intramontane with flat vast playas and salt lakes on the Qinghai-Tibet Plateau. central about 2800–2900 m a.s.l. elevation enclosed by mountain ranges reaching > 5800 Qilian Mountains 6200 eastern Kunlun Mountains. extensive of are covered gypsum or halite very subordinate additional solids. In this contribution we report chemical ...

Soda lakes of the East African Rift Valley are hyperalkaline, hypersaline extremely enriched in Na+, K+, Cl?, CO32?, HCO3?, and SiO2. In this paper, we investigate chemical evolution these production sediments by salt precipitation via evaporation. Water samples from tributary springs three (Magadi, Nasikie Engida Natron) have been experimentally studied in-situ X-ray diffraction during evapora...

Currently, fluid inclusions in halite have been frequently studied for the purpose of paleoclimate reconstruction. For example, to determine air temperature Middle Miocene (Badenian), we examine single-phase primary bottom halites (chevron and full-faceted) near-surface (cumulate) collected from salt-bearing deposits Carpathian region. Our analyses showed that temperatures near-bottom brines va...
