TL;DR: In this article, the first spectroscopic evidence to indicate Fe(III)-oxyhydroxide species forming in pyrrhotite has been presented, based on X-ray photoelectron spectroscopy and Auger Electron Spectroscopy (AES).

TL;DR: X-ray photoelectron spectroscopy (XPS) of an unoxidized surface reveals that sulphur is present as disulphide (S22−, 78 At%), monosulphides (S2−, 15%), and as polysulphite (Sn2−), where 2 < n < 8) As1− predominates, but 15% As0 is also observed.

TL;DR: In this paper, the X-ray photoelectron (XPS) spectrum of pyrite fracture surfaces, exposed for 7 h to water vapour at low pressure (10−5 Pa), showed no change to their Fe(2p) or S(2 p) X-Ray photoelectRON (Xps) spectrum, but oxygen deposition occurs as H2O, OH− and O2− (74, 19, and 7%, respectively).

TL;DR: In this paper, pyrrhotite (Fe7S8) grains 3 × 3 × 6 mm were reacted in solutions of H2SO4 (pH 3.0) for eight hours and analyzed using secondary electron microscopy (SEM), Auger electron spectroscopy (AES) and X-ray photoelectron spectrographs (XPS).

TL;DR: In this paper, the secondary ion mass spectrometer (SIMS) and X-ray photoelectron spectroscopy (XPS) were used to identify the altered layers of plagioclase reactions.
