Two petrographic methods, namely long-wave fluorescence intensity measurements and a vitrinite elasticity index were developed and used to detect incipient oxidation in coals subjected to simulated weathering conditions. The two methods are based on different physical properties of coal. However, their sensitivity in detecting changes caused by oxidation was found to be equally high.
