• Resumen

  • In areas characterized by flat and weakly incised relief built of young and lithologically uniform sediments, structural and tectonic maps are often non-existent or of no great avail. Under such conditions, the regional morphotectonic analysis of the study area may be a most useful tool to produce the required basic hydrogeological information. It consists basically of two consecutive steps, i.e., definition of stream orders and the preparation of isobase maps. In the research of Quaternary geology isobase surface analysis is regarded as a means for identifying young tectonic processes. The morphotectonic map is the final derivative of isobase maps. It portrays the basic lineaments or dislocation lines derived by analysing deviations in the directions of isobase lines, of their spreading or compression and of deviations between axes of valleys. The morphotectonic map presented in this paper portrays several major morphostructural units within the Arava graben, in the area between the Dead Sea and Nahal Paran.
