ABOUT ZINC SULFIDE

The sphalerite composition is favored at 298k by 13kJ/mol, but at 1296K the changeover to wurtzite takes place.threeThe dissimilarities between minerals may be used to estimate the temperature of equilibration. The δ13C and δ34S of coexisting carbonate minerals and sulfides can be used to determine the pH and oxygen fugacity from the ore-bearing
