The Some Plateau – Regional Identity

The Some Plateau, situated in the North - North-Western part of the Transylvanian Depression, represents one of the most controversial geographical units as its extension and subunits are concerned. The causes of this aspect are contained in the lithological, morphological, and structural-tectonic differences present in the northern part of the Transylvanian tectonic basin, as well as in the orientation of the spatial interrelation vectors and of their gravitation towards corridors, axes, or polarizing centres, defining for a functional territorial system. The critical analysis of the predecessors’ opinions leads us towards the individualization of the morphologic nucleus of the Some Plateau, consisting of the Cluj and Dej Hills, as well as the imi na Hills, in the arc of the circle shaped by the corridors of the Nad (C pu ) – Some ul Mic – Some rivers, to which a trans-Some compartment is attached, made of the Purc re -Boiu Mare Plateau and the S l truc Hills. All these subunits gravitate, naturally and anthropically, towards the above-mentioned river corridor, forming a systemic type functional unit.
