CELESTITE (Strontium Sulfate) Galleries

If the flame is a pale green, it is barite, but if the flame is red, it is celestite. The flame test works because the elements barium (Ba) and strontium (Sr) react with the flame and produce those colors. Normally barite is not blue, but many specimens of blue barite are often misidentified as celestite.

Sulfur- and strontium-isotopic geochemistry of

Isotopic compositions of most celestite and barite differ from values observed for the gypsum. Division of the deposits into two geologically and geochemically distinct groups shows that there is a general positive correlation between δ 34 S and 87 Sr 86 Sr compositions of celestite and barite in the two systems, with celestite containing lighter S and less radiogenic Sr in both groups of deposits.

The Formation of Barite and Celestite through the

Barite (BaSO 4) and celestite (SrSO 4) are the end-members of a nearly ideal solid solution. Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO 4 ·2H 2 O) or anhydrite (CaSO 4). Barite,

Synthesis of barite, celestite and barium-strontium

Crystals of synthetic barite (BaSO 4 ), celestite (SrSO 4 ), and their solid solutions were recrystallized from brine by thermal cycling. Electron probe microanalyses show that the solid solutions are homogeneous within detection limits.

2019-7-2 · The compositions of naturally occurring phases in the barite–celestite series tend not to deviate substantially from those of the series end members ().For instance, the degree of strontium substitution in marine barite is typically on the order of ∼1 to 4 mol % (2, 11, 13).Since intermediate compositions are rarely observed, some speculate that the solid solution may not be continuous.

Alternative Title: celestite. Celestine, mineral that is a naturally occurring form of strontium sulfate (SrSO 4 ). It resembles barite, barium sulfate, but is much less common. Barium is interchangeable with strontium in the crystal structure; there is a gradation between celestine and barite. Celestine

Barytes (barite or barium sulphate) is used chiefly in making mixed paints, in which white, ground, and water-floated barite is employed as a pigment. Ground barite is also used in the rubber industry and to some extent by the makers of heavy glazed paper and ink.
