Mineralogical composition of mining wastes deposited in voluminous tailing impoundments around the world is the key factor that controls retention and release of pollutants. Here we report geochemical and mineralogical investigation of one tailing impoundment from Slovakia. Ore deposit Rudňany was exploited from the end of 19th century and at 1963 the ore started to be extracted by flotation process (barite, siderite and sulfides). Waste after flotation was deposited into one tailing impoundment, which carries app...

Ulukisla (Nigde/Turkey) evaporites that compose the study area are situated in Ulukisla Basin at the east of Nigde, South of Central Anatolia. The aim of the study is to investigate the geological, mineralogical and geochemical properties of the gypsum and anhydrites in Ulukisla Evaporites and to determine usage area of the evaporites as an industrial material. For this scope, 50 anhydrite and gypsum samples were collected systematically from the Ulukisla evaporites in 900 m thick area. By XRD (X - Ray Diffraction...

Barite occurrences east of Istanbul (NW Turkey) are compared major mineralogical and geochemical properties, and identified depositional origins. Sile barite occurrence, which is near Blacksea, north east of Istanbul, is alternated with Triassic sandstone. Petrographic observations reveal that barite grains are found out in the sand stones. Chemical analyses are conducted on eighteen samples via AAS (Atomic Absorption Spectroscopy) equipment for detection of Cu, Zn, Pb, Sr, Cd and Ni concentrations. Because of a v...

The groundwater quality survey can be made by using monitoring and analysis tools that are able to manipulate time-series large datasets showing a spatial reference. Data correlation with the spatial distribution of the hydrogeological structures is compulsory. Within the urban environment the problem show a larger complexity because of the infrastructure interaction. Within the collaboration framework between several Spanish and Romanian institutions a management, analysis, and modeling hydrogeological platform f...

Glauberite mineralization from Cayirhan, Ankara (Central Anatolia) has been investigated and identified the major mineralogical, petrographical and geochemical properties. Glauberite occurrence, a sodium calcium sulfate mineral (Na2Ca(SO4)2) by evaporation, is underneath the gypsum mineralization which accumulated at the contact zone between Pliocene aged Ucyatak and Softa formations. The mineralization is related to clay and mudstone, and accompanies with thenardite, gypsum, anhydrite, mirabilite and blodite. Maj...
