Before 1953 almost no barite deposits were known in Pakistan. Discovery of such deposits relatively close to oil fields in northern Pakistan in 1953 led to increased barite production from 1957 to 1961 and to doubling of production in 1962, firmly establishing new industry for the country. During 1962 and 1963, most of the known barite deposits in …
Barite Hill is a stratiform gold-silver deposit associated with base metal sulfides and barite in greenschist facies rocks.

The δ 18 O values range between 3.7 and 15.3‰, with significant variation between the different deposit types. Barite from the carbonate-hosted deposits at Lavrion has high δ 18 O values between 10.5 and 15.3‰, where lower δ 18 O values correlate with higher δ 34 S values. Barite from Serifos has δ 18 O values between 8.8 and 12.8‰.

The Dahebian barite deposit is located on the southeastern margin of the Yangtze Craton, South China, which is bounded to the north and southeast by the North China Craton and the South China fold belt, respectively (Fig. 1).During the late Sinian (Neoproterozoic) to the early Cambrian, the studied area was generally a passive …
North Africa in 1994; 2,400 tons of barite in Middle and Far East in the same year and 355 tons barite in South Africa. Kaiser et al. (1987) described barite deposits in veins mostly metamorphosed in rocks of the Piedmont belt, ia U.S.A. Barite veins occur widely in the United States of America and other parts of the world.
The Lodève Basin, located 50 km northwestern of Montpellier in the south of the French Massif Central, is a 180 km 2 cuvette-shaped half graben (Fig. 1 A). The half-graben geometry of the basin is linked to a gravitational collapse along the Hercynian mountain chain from Late Carboniferous to Late Permian (Echtler and Malavieille, …
Barite that is used as an aggregate in a "heavy" cement is crushed and screened to a uniform size. Most barite is ground to a small, uniform size before it is used as a filler or …
The Fengjia barite–fluorite deposit is one of the typ-ical deposits in the barite–fluorite belt of southeast Sichuan, and barite–fluorite ore is hosted mainly in the Fenxiang and Honghuayuan Formations (Fig. 4). The NW-trending fault controls the NW-extension of the barite–fluorite ore veins and their spatial distribu-tion (Fig. 3).

The barite deposits that emerge as veins and lodes within or along the contact zones of recrystallized limestone and dolomite units of Cambrian Degirmentas Formation are of epigenetic character. Depositional styles, mineral paragenesis, host rock alteration styles, and high SrO contents of the barites suggest a hydrothermal origin for …

In the western portion of the State of Goias, Central Brazil, base-met al deposits typical of volcanic-plutonic arcs occur. Up- to-date studies suggest that porphyry Cu-Au, (volcanogenic ?) hydrothermal exhalative Cu-Au and stratiform, submarine exhalative Au-Ag-Ba are present. Although restricted, the present state of knowledge on …

Barite is found within host rock or co-occurs with barite-associated calcite within veins or large fractures. The host rock in which barite is found belongs to the Lekhwair (predominantly) and Kharaib formations. Typically, barite is present at the rim of the vein, whereas barite-associated calcite fills the inner space of the fractures (Fig. 3A).
For example, barite occurs at Lake Fletcher as narrow veins in rocks of the Meguma Group (Fig. 1, Felderhof 1978), as a trace constituent in dolostone at the Gays River Zn-Pb deposit (Kontak 1992), replacing sideritized Carboniferous limestone at the past-producing Walton deposit (Boyle 1972) and in Horton Group siltstone at the stillproductive ...
