Abstract: In west-east direction, the Selec Block of the Považský Inovec Mts consists of three geologically and tectonically distinct segments of Tatricum.
1) Eastern segment is characterized by dominance of the Tatricum crystalline basement rocks (mica schists), subautochthonous position and internally imbricated structure with thrust sheets of Permian, Triassic and Upper Cretaceous (Horné Belice Group) rocks. Rocks of the Fatricum and Hronicum are rudimentarily preserved along the eastern margin of the block.
2) Central segment represents deformed – folded and sheared structure, composed of the Tatricum crystalline basement (orthogneiss) and sedimentary rocks of Carboniferous to Triassic age. This segment largely corresponds to lithology surrounding the Hôrka shear zone and the Selec thrust.
3) The western segment is represented by internally imbricated structure, containing Variscan (Lower Carboniferous) crystalline basement rocks (diapthorites of different types), Permian to Triassic rocks of the Tatricum and thin-skinned nappe complexes of Fatricum and Hronicum.
