Geology and genesis of the sedimenthosted barite deposits in the Lasbela and Khuzdar districts of Balochistan, Pakistan have been studied and described.

The barium deposits in Ankang and Xunyang counties, Shaanxi Province, China, occur in the northernmost part of the worldclass barium metallogenic belt in south Qinling. The deposits are hosted by the Lower Silurian carbonaceous siliceous rocks, with a unique combination of barite and witherite.

barite metallogenesis may be applied to other types of mineral deposits formed in continentalmargin settings (for example, gold, phosphorite). Stratiform Barite Deposits of Nevada Regional Geology Stratiform barite deposits in Nevada are concordant within siliceous sedimentary strata .

The recognition of the Tom as an example of sedimenthosted, submarine exhalative mineralization, and the recent discovery of further occurrences of similar mineralization at the same stratigraphic horizon within the Selwyn Basin, raises the possibility that the eastern Yukon could become a very important PbZnbarite mining camp.

Sedimentary exhalative deposits (SedEx deposits) are ore deposits which are interpreted to have been formed by release of orebearing hydrothermal fluids into a water reservoir (usually the ocean), resulting in the precipitation of stratiform ore.. SedEx deposits are the most important source of lead, zinc and barite, a major contributor of silver, copper, gold, bismuth and tungsten

2009 Red Dog produced a record 582,500 mt Zn and 131,500 mt Pb. Main orebody expected to be exhausted by mid 2011. Expecting formal approval for Aqqaluk deposit which would maintain production at current levels until 2031.

Geological, microthermometric, and isotopic data provided in this paper are focused on defining the genesis of the stratabound barite deposits of Múzquiz, Coahuila, Mexico. 2. Geology. The structural and paleogeographic features of northeastern Mexico during the Mesozoic were determined by three major geological events.

chemical difference between the two types of barite deposits. It was hoped that by studying the trace element and isotopic composition of the barites that some light would be shed on the genesis of the barite deposits. Only purified barites were analyzed so that the results would reflect only'' dif

In 1996, a memorandum of understanding was signed by representatives of the Geological Survey and Kennecott Greens Creek Mining Company to initiate a cooperative applied research project focused on the Greens Creek massive sulfide deposit in southeastern Alaska. The goals of the project were consistent with the mandate of the Geological Survey Mineral Resources Program to maintain a ...

The occurrence of barite seams interstratified with quaftzite of the Ghattihosahalli schist belt was first reported by Radhakrishna Sreenivasaiya (1974). Subsequently, besides exploration to assess the size and quality of the deposit by the State Department of Mines and Geology (Annaiya Srinivasaiah 1976), the barite

Abstract Barite deposits of the Lasbela District, Balochistan, hosted in the Ferozabad Group (FG) of Jurassic are relatively pure and have BaO value ranging from to % with minor amounts of Sr, Fe and Ca. The measured average density of the studied samples ( g/cm3) is compatible with the API13A specification. The quantity of watersoluble alkaline earth metals found is very low ...

"Feldspar" is the name of a large group of rockforming silicate minerals that make up over 50% of Earth''s crust. [1] They are found in igneous, metamorphic, and sedimentary rocks in all parts of the world. Feldspar minerals have very similar structures, chemical compositions, and physical properties.
