| Abstract: | 44 Δ13C-values for carbonaceous matter in a metamorphic profile from the Swiss Alps have been determined. The analyzed samples range from unmetamorphosed sediments to staurolite schists. The carbon isotopic composition is more-or-less constant with δ-values around ?25%. in the unmetamorphosed sediments, but shifts towards higher 13C-content with increasing grade of metamorphism. δ13C values of around ?11%. were measured in the rocks of the highest metamorphic grade. |
