,Selbstarch?ologie als Ich-Arbeit, TTFA have shown it to be able to produce elemental profiles of the mineral phases in coal (8). An advantage of TTFA is its ability to produce reliable quantitative results with a minimun of prior knowledge. In order to further explore the utility of this approach, a data set consisting of physicall
