Abstract
The objective of this study was to assess high energy UV photo-oxidation, 13C CP/MAS NMR spectroscopy and 14C
activity measurements for their suitability in dierentiating carbon derived from plant material and that derived from
lignite. The conceptual approach included analysis of bulk soil samples and physical fractions of lignite-rich mine soils.
