摘要：

Graphitic schists from the Pennine Basement, Tauern Window, Austria, contain fragments of pteridophyll leaves. They are preserved, despite the overall strong deformation and metamorphism at amphibolite facies conditions (approximately 525-degrees-C, 750 +/- 100 MPa), due to a particular strain path with volume loss by pressure solution. They were determined as cf. Callipteridium sp. indicating a Permo-Carboniferous age. This depositional age is similar to radiometric age data obtained for the intrusion of nearby metagranitoids, indicating either tectonic contacts between the metagranitoids and the graphite schists, or a very active and rapidly changing tectonic regime during the Hercynian event.
