| Abstract: | Mössbauer spectroscopy of three suites of oxidized coals shows that the transformation of pyrite to FeOOH correlates with other parameters of oxidation. As pyrite is very common in coals and the transformation to FeOOH is sensitive to small degrees of oxidation, the Mössbauer technique shows considerable promise as a means for the detection of coal oxidation. |
