Volcanic-morphotectonic-zoning in the morphostructural analysis of relief: the case of the municipality of Managua, Nicaragua
Based on the relationship between geologic structures and landforms, twelve morphotectonic-volcanic units (MTVU) were defined. The characterization of the relief resulting from the fragmentation of Nicaraguan volcanic chain and the formation of the Managua graben is provided through these units. Tak...

| Sumario: | Based on the relationship between geologic structures and landforms, twelve morphotectonic-volcanic units (MTVU) were defined. The characterization of the relief resulting from the fragmentation of Nicaraguan volcanic chain and the formation of the Managua graben is provided through these units. Taking into account criteria associated with morphotectonic, morphostructural and morphometric attributes, as well as elements of relief, a map (1:50 000 scale) was generated. The criteria considered included the analysis of the structural orientation of the relief, comprehensive morphometric evaluation of geomorphological categories, the identification and interpretation of geological-structural features, the analysis of linear and annular morpho-elements, structural analysis with correlative lithostratigraphic relationships of the substrate, and the interpretation of the structural patterns of the hydrographic network. The MTVU articulate in a geosystemic way the expression of the structure and geological formation, and recognize the significance of neotectonic activity in the formation and differentiation of the relief. |
