Abstract. A proposed null hypothesis for fluvial terrace formation is that internally generated or autogenic processes, such as lateral migration and river-bend cutoff, produce variabilities in channel incision lead to the abandonment of floodplain segments terraces. Alternatively, terraces have potential record past environmental changes from external forcings include temporal sea level hydroc...
High resolution scanning tunneling microscopy (HRSTM) images of i-Al–Pd–Mn reveal wide flat terraces along the 5-fold (5f) direction with quasiperiodic atomic arrangements that are consistent with the expected structure of the dense pure aluminum planes of the bulk material as defined by 6D-models. This makes encouraging the exploration by HRSTM of a QC surface to better understand its 3D real ...
Extended abstract 1-Introduction The natural environment is affected by climate, and its changes have different geomorphic forms. The dominance of different climatic phases and changes in the balance of matter and energy cause different shaping systems in the environment. Ancient lakes are one of the geomorphic forms of the Quaternary period, and today many of these lakes are either complete...
introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...
