The barites that precipitated below the sediment–water interface have higher δ34S values, suggesting that the fluids were relatively reduced with molar dissolved barium in excess of dissolved sulfate. Those samples were exposed at the seafloor by uplift along faults and are composed predominantly of massive, brecciated, and vein barite. ...

Barites can occur as gangue minerals in various mineral veins, in limestones, sandstones and like deposits [11]. Barite is chemically inert and insoluble in water or oil. About 80% of barite in the world is used as a weighting material in drilling fluids in oil and gas exploration to suppress high formation pressures and prevent blow out [12].

The δ34S composition of the barites averages 20.6 ± 2‰ V-CDT and is indicative for a seawater origin of sulfur. Sulfate was sourced either from evaporite minerals (e.g., gypsum) present in the Early Mesozoic sedimentary sequence or was originally concentrated in the bittern brine. While the timing of mineralization remains enigmatic …

Despite the abundance of beautiful crystals, cut barites are uncommon, particularly those with vibrant colors. The hardness of barite ranges from 3 to 3.5. Due to its high specific gravity, this mineral received its name from the Greek word for "heavy" and was first described by D.L.G. Karsten in 1800.

Physical Properties of Baryte. One very typical property of baryte is its high density - 4.5 g/cm3. It can be easily distinguished from many similar minerals by its inapropriate weight. Baryte comes in several different colors, including white, orange, yellow, pink, red, brown, purple, green, blue, black, and gray.

Barite is a mineral composed of barium sulfate (BaSO 4 ). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and ...

Summary. In the modern marine environment, barium isotope (δ138Ba) variations are primarily driven by barite cycling—barite incorporates 'light' Ba isotopes from solution, rendering the residual Ba reservoir enriched in 'heavy' Ba isotopes by a complementary amount. Since the processes of barite precipitation and dissolution are …
