We examine the tectonic geomorphology of La Sila, Calabria, southern Italy, a high-standing (1500 m) plateau surrounded by crustal extension, with map, DEM, and field data. These data are used to constrain a simple geodynamic model that describes short-wavelength deformation of the plateau rim. Topographic metrics including drainage patterns, river longitudinal profiles, and swath profiles are ...

background: the segmentation of cancerous areas in breast images is important for the early detection of disease. thermal imaging has advantages, such as being non-invasive, non-radiation, passive, quick, painless, inexpensive, and non-contact. imaging technique is the focus of this research. methods: the proposed model in this paper is a combination of surf and corners that are very resistant....

Introduction: Crustal plateaus are a major class of tectonic features on Venus surface, and its study is essential in order to understand the geological evolution previous to the global resurfacing process. These regional units are flat topped highlands formed by tessera terrain, characterized by superposition of crosscutting structures [1-2], with complex tectonic patterns; also intratessera v...

The Eel River draining the Coast Range of northwestern California has the highest recorded average suspended sediment yield per drainage area of any river of its size or larger unaffected by volcanic eruptions or active glaciers in the conterminous United States (1,720 t/kmyr from 9,390 km; Brown and Ritter, 1971). These high rates of erosion and sediment transport result from a combination of ...

study area is located in the central kopehdagh north of bojnurd and shirvan cities, between kakli and raz villages. aim of this research is separating high activity area from low activity. in this study, in order to evaluate rate of tectonic activity, stream length-gradient index (sl), ratio of valley floor width to valley height (vf), transverse topographic system (t), hypsometric integral (hi...

[1] Back‐arc basin evolution is driven by processes active at the main subduction zone typically assuming the transition from an extensional back‐arc, during the retreat of a mature slab, to a contractional basin, during high‐strain collisional processes. Such a transition is observed in the Black Sea, where the accurate quantification of shortening effects is hampered by the kinematically uncl...

The surface of Venus displays several tectonized terrains in which the morphologic characteristics of the original materials are almost completely erased by superposed tectonic structures whose large dimensions (»100 km) suggest formation related to mantle convection. The characteristics of these tectonized terrains are in contrast to volcanic units in which tectonic structures are less signifi...
