In aging experiments at 65C, the conversion of precursor amorphous FeS depends on these geologically relevant variables: concentration of sulfur-contributing species, acidity, redox state, time, Fe(II)/S(-II) ratio in solution, and addition of an organic ligand (citrate). The induced polarization method is the sister of the DC resistivity method. In an alternating electrical field, the current and electrical field are not in phase. There is a small-phase lag between the two. This phase lag is related to polarization phenomena around the grains involving the electrical double layer.Aug 10, 2021 · Marcasite has a metallic sheen and is a pale yellow to practically white in color.
