Travertine deposits are a kind of continental carbonates that form in specific chemical, physical and biological conditions. Garab travertines in southeast of Mashhad are studied based on field, geochemistry (elemental and stable isotope analysis) and hydro-geochemistry analysis. Field and petrographic characterization led to recognize of crystalline crust, raft, foam, shrub, laminated, black m...

This study aims to evaluate the hydro-chemical characteristics of Ouargla, Algeria basin groundwaters harvested from Mio Pliocene aquifer. The covered 70 samples; physical parameters, potential hydrogen (pH), and electrical conductivity EC ?S.cm?1 were determined in situ, using a multiparameter; laboratory analysis included dry residuals DR (mg/L), calcium Ca2+ magnesium Mg2+ sodium Na+ potassi...

Groundwater contamination by fluoride (F) can result from the natural dissolution of minerals from subterranean strata. These inorganic contaminant in drinking water is known to cause serious health problems when the maximum contaminant levels (MCL) exceed 1.5 mg/L. The aim of this study was to correlate the high fluoride content in the groundwater of the region to the geochemistry of the water...

Based on the data of geological drill holes, roadway drifting, transient electromagnetic exploration, mine water inrushes, hydro-geochemistry and water levels on each side of the Haotang Normal Fault, this paper studies the waterbearing capacity and water conductivity of the fault in the Pingdingshan Tian’an Mining Company Limited No. 7 Coal Mine. The results indicate that the Haotang Fault is ...

The use of the Hierarchical Cluster Analysis (HCA) in conjunction with a multi-sample graphical technique offers robust indicator geochemical evolution ground water. HCA applied to identify processes controlling water geochemistry shallow aquifer system outer plains Jammu and Kashmir State. has good agreement hydro chemical facies reflect process pattern flow geological formation it explains di...

Agricultural production may cause groundwater pollution. This study investigated the characteristics of shallow pollution in a typical black land agricultural area Northeastern China and geochemical behavior major pollutants. A total 27 23 samples were collected for measuring on-site parameters components 2000 2014, respectively. The improved integrated approach was used to assess contamination...

Groundwater is often the main or only source of fresh water supply in arid to semi-arid rural areas owing decreasing rainfall patterns, reduced availability surface and socioeconomic activities. It important understand hydro-geochemical processes influencing groundwater quality for improved management sustainability resources improve livelihoods. To process hydro-geochemistry Soutpansberg regio...
