SUBDIVISION OF THE PYRITE GROUP, AND A CHEMICAL

2006-8-30  Minerals in the pyrite group may be divided into pyrite, ullmannite and cobaltite subgroups based upon the 010 and 011 reflections in powder X-ray-diffraction data. The subgroups, which are listed in Table l, are based upon the powder X-ray-diffraction data in the Group Data Book of the Mineral Powder Diffraction File by Bayliss et al. (1e83).

mp-226: FeS2 (cubic, Pa-3, 205) Materials Project

FeS2 is Pyrite structured and crystallizes in the cubic Pa-3 space group. The structure is three-dimensional. Fe3+ is bonded to six equivalent S+1.50- atoms to form corner-sharing FeS6 octahedra. The corner-sharing octahedral tilt angles are 64°. All Fe–S bond lengths are 2.25 Å. S+1.50- is bonded in a 3-coordinate geometry to three equivalent Fe3+ atoms.

Crystal Chemistry And Crystallography Of Some Minerals

Isotropic pyrite belongs to space group Pa3.Anisotropic pyrite, like cobaltite, is interpreted as a sextuplet of interpenetrating, twin-related, orthorhombic (space group Pca2 1) domains about a 3 twin axis [111]. The Fe atom in pyrite is considered to move away from the three S atoms with single bonds to Fe and toward the three S atoms with double bonds to Fe.

Thermal desulfurization of pyrite: An in situ high-T

With further increase in temperature to 1073 K, all the pyrite transformed to pyrrhotite (Fe1-xS

Pyrite Mineral Uses and Properties

Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral. It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite

An emerging picture of Neoproterozoic ocean chemistry

Observations from the Chuar Group are consistent with these hypotheses, and gain further support from pyrite and sulfate sulfur isotope abundances. In general, Chuar data support the hypothesis that ferruginous subsurface waters returned to the oceans, replacing euxinia, well before the Ediacaran emergence of persistently oxygenated conditions
