A poorly defined boundary between the Nubia and Eurasian plates runs along Northern Tunisian continental margin. The Tunisia margin is deformed by a slow NW–SE trending convergence resulting in diffuse deformation zone with scarce scattered seismicity compared to seismic activity into neighboring regions east west boundary. area has been studied therefore its recent evolution almost unknown, pa...

The concept of tectonics has always been dependent on the duality between technology and representation. Botticher (1852) acknowledged the tectonic duality between structure and cladding. Semper (1951), conversely, highlighted the role of the joint in tectonics within its four elements of earthwork, hearth, framework–roof and enclosing membrane. His approach promoted the essence of the presence...

Introduction Changes in land surface shape in active tectonic  zones result from interplay between tectonic forces and surface processes (Keller and Pinter, 1996; Keller et al., 1999). Salt Domes  are dome-shaped Geological structures whose central core is composed of salt. Their economic importance is due to the location of oil tanks in structures with salt domes and also the presence of sulf...

abstract alluvial fans are the most striking phenomena o fluvial geomorphology . these forms are found in frount of mountains and pediments of arid and semiarid zones . alluvial fans are affected by climate changes and tectonics . occurring of tectonic events lead to reaction of alluvial fans . some of these reactions appear on dissection of alluvial fans and displacement of depocenters on allu...

Debate about the relative roles of catastrophic v. continuous processes of landform evolution is as old as the discipline of Earth Science itself. Over the last 10 years or so, research in the Earth Sciences has focussed strongly on the Earth’s surface and particularly in terms of quantifying rates of processes. This research parallels developments in geomorphology and sedimentology in the quan...
