The geology and structures of two windows (the Mauken and the Divielva windows, see fig. 1) are outlined. For the Precambrian supracrustal rocks of the Mauken window, two formations names and one group name are suggested. Hyolithus zone sediments in autochthonous position along the southern margin of the Mauken window show that the Caledonian thrusting exeeded 70 km. In both window structures \"Relief\u00CFberschiebung\" took place. A magnetic anomaly in the Mauken window is explained by local concentrations of normally accessoric magnetite in an antiformal hinge zone in sericite-chlorite schists. The relations between an E-W directed magnetic anomaly and the structures of the Divielva window are discussed.
