Anhydrite Wikipedia

Anhydrite, or anhydrous calcium sulfate, is a mineral with the chemical formula CaSO 4.It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry.It is not isomorphous with the orthorhombic barium and strontium sulfates, as might be expected from the chemical formulas.. Distinctly developed crystals are somewhat rare, the

Anhydrite Pacific Marine Environmental Laboratory

Such phase separation is on-going in the ASHES vent field at Axial. At ASHES, the vapor and brine phases come out in different areas of the vent field and they produce very different chimneys. Vapor phase chimneys, like Virgin mound, are composed almost entirely of anhydrite and are very fragile.

Origin of fluids and anhydrite precipitation in the

15-12-2003· Anhydrite samples collected from the Grimsey field average 21.6 wt.% Ca, 1475 ppm Sr and 3.47 wt.% Mg. The average molar Sr/Ca ratio is 3.3×10 −3. Sulfur isotopes of anhydrite have typical seawater values of 22±0.7‰ δ 34 S, indicating a seawater source for SO 4 2−.

Crain's Petrophysical Handbook Crain's Rules For Visual

On Sandstone Units logs, separation for sandstone is near zero, limestone is about 7 porosity units, dolomite is 15 or more, and anhydrite is 22 or more. Visual determination of lithology (in addition to identifying shale as discussed earlier) is done by noting the quantity of density neutron separation and/or by noting absolute values of the photo electric curve.
