Barite (Barium)
Barite (barium sulfate, BaSO4) is vital to the oil and gas industry because it is a key constituent of the mud used to drill oil and gas wells. Elemental barium is an additive in optical glass, ceramic glazes, and other products. |

Sulfur isotope analyses of mineral deposits: sulfide minerals in epithermal veins of the Lowland mining district, Montana, USA and anhydrite associated with the Black Angel zinc-lead-silver deposit, Greenland
Sulfur isotope determinations (34S/32S ratios) for sulfur-bearing minerals collected from epithermal veins in this area and from metasedimentary rocks that host the Black Angel zinc-lead-silver deposit. Samples were collected by cooperators as parts of larger ore genesis studies. Data are provided in CSV format. |
