[email protected] geochronology Abstract New Rb-Sr biotite age data from meta-granitoids of the Seckau Nappe (Eastern Alps) are discussed to constrain its tectonometa- morphic evolution. Within the basement of the Seckau Nappe a clear distinction between S- and I- Type granitoids can be establi- shed. The S- type granites are mainly part
