“…The experimental values of the lattice parameters [18][19][20] have been chosen for our calculations as shown in Table I. Although the ZnO usually has the wurtzite structure, 21 it is known that the zinc-blende structure exists as a meta stable state.…”

We have calculated the quasiparticle band gaps of ZnO, ZnS, and ZnSe in zinc-blende structure within the GW approximation using a full random-phase approximation dielectric matrix. The linear muffin-tin orbital basis was used for this calculation and the 3d orbitals of the Zn atom were treated as valence band in every case. The calculated band gaps are 3.59, 3.97, and 3.10 eV for ZnO, ZnS, and ZnSe, respectively. The gaps of ZnS and ZnSe are in good agreement with the experimental values and so is the gap of ZnO if we compare it with the experimental optical gap of wurtzite ZnO.

“…5. The lattice parameter for natural sphalerites had been measured by Aswegen and Verleger (1960) but only up to an FeS mole fraction of 0.215. Barton and Toulmin (1966), extended the range of measured compositions up to the limit of FeS solubility.…”

“…Production of molecular oxide species (i.e., 232 Th 16 O/ 232 Th) was maintained at <0.2%. The monitored isotopes included 51 V, 53 Cr, 55 Mn, 57 Fe, 59 Co, 60 Ni, 65 Cu, 66 Zn, 69 Ga, 72 Ge, 75 As, 77 Se, 95 Mo, 107 Ag, 111 Cd, 115 In, 118 Sn, 121 Sb, 125 Te, 197 Au, 202 Hg, 205 Tl, 208 Pb, and 209 Bi. The element contents were calibrated against reference materials of USGS MASS-1 and USGS GSD-1g using 66 Zn as an internal standard for sphalerite and würtzite, and 57 Fe for pyrite, respectively [43,44].…”

Minerals of the Zn-Cd-S-Se system that formed by moderately reduced ~800–850 °C combustion metamorphic (CM) alteration of marly sediments were found in marbles from central Jordan. Their precursor sediments contain Se- and Ni-enriched authigenic pyrite and ZnS modifications with high Cd enrichment (up to ~10 wt%) and elevated concentrations of Cu, Sb, Ag, Mo, and Pb. The marbles are composed of calcite, carbonate-fluorapatite, spurrite, and brownmillerite and characterized by high P, Zn, Cd, U, and elevated Se, Ni, V, and Mo contents. Main accessories are either Zn-bearing oxides or sphalerite, greenockite, and Ca-Fe-Ni-Cu-O-S-Se oxychalcogenides. CM alteration lead to compositional homogenization of metamorphic sphalerite, for which trace-element suites become less diverse than in the authigenic ZnS. The CM sphalerites contain up to ~14 wt% Cd and ~6.7 wt% Se but are poor in Fe (means 1.4–2.2 wt%), and bear 100–250 ppm Co, Ni, and Hg. Sphalerite (Zn,Cd,Fe)(S,O,Se)cub is a homogeneous solid solution with a unit cell smaller than in ZnScub as a result of S2− → O2− substitution (a = 5.40852(12) Å, V = 158.211(6) Å3). The amount of lattice-bound oxygen in the CM sphalerite is within the range for synthetic ZnS1−xOx crystals (0 < x ≤ 0.05) growing at 900 °C.
