ABSTRACT. – Tectonic and Structural Relationships in Silvania Mountains. The structural landforms were defined by the fault systems present in the area, as dislocations following the Alpine orogenic system, which imposed the subaerial and submerged dynamics of the landforms, coordinating in this way the modeling systems with the geological time scale, on the basis of complex tectonic and structural, morphotectonic and morphoselection relationships between the geologic structure, the tectonic factors and the external geodynamic agents. The Meseș hemi‐anticline is different from the horst of Plopiş as well as Șimleu and Coșeiu Hillocks due to the dynamics, intensity and magnitude of the faulting phenomenon which controlled the sedimentation process and the placement of eruptive bodies. The morphoselection relationships, in which the main role belonged to the selective erosion, facilitated the development of three types of structural (tabular, monoclinal and folded) landforms.
Keywords: Silvania Mountains, tectonics, collisional chain, geomorphologic structure, relationships.
