Abstract:
Rock-Eval (RE) pyrolysis has been widely used by petroleum industry and by geosciences for decades. It provides information about the amount, type and and maturity of the organic matter and the petroleum potential of rocks. Although this technique was originally designed for studying the mature organic matter from source rocks, recent work showed that it could be applied also for evaluating the amount and properties of immature organic matter from Recent sediments (Sanei et al. 2005) and soils (Di Giovanni et al. 1998). In addition to the basic information that is given by the bulk RE data, mathematical deconvolution of the pyrograms allows one to follow the evolution of the humification process. It can also be used to quantify the relative contribution of the thermally labile and resistant biomolecules and that of humic substances in organic matter in soils (Disnar et al. 2003, Hetényi et al. 2005) and in wetlands (Hetényi et al. 2006).
