SUMMARY
Peat decomposition is locally processed at the micro scale, owing mainly to the diversity of redox condition because of the heterogeneous distribution of micro-pores in peat. In this study, we evaluated this heterogeneity in peat decomposition in order to obtain useful data on the peat decomposition process. To this end, we differentiated types of peat micro-fragments to describe the diversity of decomposed states in peat. The differentiation was based on their chemical structural analysis using Fourier transform infrared (FTIR) micro-spectroscopy and multivariate analysis. Based on the results of this analysis, the observed peat fragments were classified into five types…
