AbstractAbstract
[en] Some metapelites of different metamorphic grade have been investigated with regard to their content of chemically fixed nitrogen (NH4+-N). In addition the isotope ratio has been determined. It has been found that with increasing metamorphic grade the NH4+-N content increases and the 15N/14N ratio decreases. The 15N enrichment was primarily controlled by the metamorphic grade of the metamorphic rocks. During the metamorphism isotopic exchange processes between NH4+-N and N2 or NH3 were responsible for the nitrogen fractionation
