متن کاملBedded Barite in the Geologic Record
Barite occurs throughout tlie gcologic ~.ecortl as massive beds, laminations, rosettes, and nodules. The niost importan( scientific and econo~iiic occurrences of barite are stratabound and stratifor~n massive betis from the Early Arcliean and tlie Early to Middle Paleozoic. Paleozoic beddecl barites are by far thc most volu~netricellp significant deposits in tlie geologic record. Additional occ...
متن کاملGeochemical characteristics of barite occurrences in the Palaeozoic complex of South-eastern Bosnia and their relationship to the barite deposits of the Mid-Bosnian Schist Mountains
In Palaeozoic rocks of South-eastern Bosnia (SEB) there are numerous, but very small vein and replacement barite ore deposits containing up to 10% Pb-Zn-Fe-Cu sulphides. Their geochemical characteristics are compared with large barite monosulphide (Hg-tetrahedrite) ore deposits in Mid-Bosnian Schist Mountains (MBSM). The 87Sr/86Sr isotope ratios in the barites of both areas are very similar, (0...
متن کاملControl of Barite Morphology by Double-Hydrophilic Block Copolymers
Barite particles with a rich variety of well-defined morphologies have been synthesized by using double-hydrophilic block copolymers (which consist of a hydrophilic solvating block and a hydrophilic binding block) as crystal growth modifiers to direct the controlled precipitation of barium sulfate from aqueous solution. The influences of variation in functional group and molecular structure of ...
متن کاملEstimation of bioavailability of metals from drilling mud barite.
Drilling mud and associated drill cuttings are the largest volume wastes associated with drilling of oil and gas wells and often are discharged to the ocean from offshore drilling platforms. Barite (BaSO4) often is added as a weighting agent to drilling muds to counteract pressure in the geologic formations being drilled, preventing a blowout. Some commercial drilling mud barites contain elevat...
