THE ROLE OF THE GEOLOGICAL COMPOSITION IN THE STRUCTURAL MORPHOLOGY OF THE TERRITORY OF ALBANIA

In the context of geological composition, the territory of Albania closely depends on the geographic position. The presence of our country in the alpine-Mediterranean fold belt and the geological structures, called Albanide, have determined the intense development of the internal tectonic processes, as well as the external processes. The tectonic regime of the geological structures during the Miocene epoch to the Quaternary period, was accompanied by reverse faults and thrust faults one over the other of the tectonic areas of Albania. The morphologic and morphogenetic complex of the relief was created during the tectogenic period, especially during the tecto-orogenesis, where as consequence diverse magmatic. terrigenous and carbonates rocks were created. The highly pronounced character of the differential tectonic movements during morphotectonic evolution, especially during the plio-quaternary period, has created the actual morphological features of the relief of Albania.In the context of geological composition, the territory of Albania closely depends on the geographic position.

The highly pronounced character of the differential tectonic movements during morphotectonic evolution, especially during the plio-quaternary period, has created the actual morphological features of the relief of Albania.The migration of orogenesis from east to west is conditioned by the dominance of mountainous ranges and ridges in the eastern and central parts, as well as in the fields and lowlands of the western part of Albania. The relief is distinguished by its diversified morphogenetic traits, due to the highly complex morphotectonic evolution, a large number of carbonate, terrigenous and magmatic rocks, as well as the significant influence of the outward processes. Due to the existence of composition of the large number of tectonic faults as well as the high values of tectonic uplift and downlift, the genetic composition of the structural relief was also created. Each of the sub-types within the structural relief is closely related to the presence of complex geological structures such as anticlinal, synclinal, monoclinal and aclinal structures. An important role have the structural landforms formed in the structures of faulting type, thus in the horst and graben structures, which are associated with very large morphological contrasts of the relief.A part of the horst and graben structures during the last period of pliocene and during the quaternary was involved by intense tectonic lifting movements, resulting to a fragmentation of flat bottom of ex-former depressions, and consequently they were transformed into depressions with fragmented bottom. A large part of structural relief landforms, such as structural benches, flat surfaces formed in the aclinal structure, structural surfaces, denudational surfaces and concave fragment of front of the cuestas, have been used for the construction of rural and urban settlements, for the road infrastructure network, the construction of human buildings, as well farmlands for the country's economy. The detailed analysis of the structural relief features, based on the characteristics of geological construction, enables prospects for taking measures against geomorphological, seismic and hydrological hazards.
