Abstrakt: An analysis of magnetic fabric has been performed in weakly deformed Paleocene-Eocene limestone adjacent to two subparallel ramp-related folds (Akseki and Ormana folds) from the western Taurus (Turkey). The magnetic fabric of tectonic origin records two trends of well-defined magnetic lineation: N160 ° ± 7 ° and N130 ° ± 14 ° in front of the Akseki and Ormana folds, respectively. The trend of the magnetic lineation is oblique to the Akseki fold, whereas in the Ormana fold, magnetic lineation and fold axis are subparallel. The observed change in the trend of magnetic lineation is probably linked to a change of the shortening direction that occurred during the development of the thrust system. This shows that the two subparallel folds result from two different translation vectors.
