study area is located in west of iran with relatively rough topography. lithologic units in the region belong from jurassic and cretaccous till recent era. the study area of the alvand mountain region is related to the tectonic zone of the sanandaj-sirjan region and the area dominant neo-tectonic regime appears to be compressional-extensional type. one of the identification tools to find out th...

The Dawn Framing Camera (FC) has imaged the northern hemisphere of the Asteroid (4) Vesta at high spatial resolution and coverage. This study represents the first investigation of the overall geology of the northern hemisphere (22–90 N, quadrangles Av-1, 2, 3, 4 and 5) using these unique Dawn mission observations. We have compiled a morphologic map and performed crater size–frequency distributi...

1- Introduction: Geomorphic investigation is a powerful tool for studies of active tectonics in active regions. Active faults and folds commonly have topography that can assist in identifying different geomorphic or structural segments along a structure, and estimating the potentially most active segments. In tectonically active regions, drainage networks and topographic features can be used as...

Fractal analysis of earthquakes, lineages and waterways are considered as one of the practical tools to evaluate tectonic activity. With the help of fractal analysis, structural maturity and tectonic dynamics can be evaluated. In this research, using fractal analysis and box counting method and fild studies, the measured fractal dimensions for the designed network of Alborz province were studie...

The singular events which occurred at the initiation of the Flood should have produced a geologic signature with at least five characteristics: (a) a mechanical-erosional discontinuity (ED) identified by regional structural analysis—probably the most significant unconformity in any given area; (b) a time or age discontinuity (AD) identified by coarse sediments above the erosional unconformity c...

The paper will describe a large scale design study involving a total of 1100 middle and high school students from California and Massachusetts who collaborated on-line about plate tectonic activity in their respective location. The students, drawn from demographically diverse schools, collaborated online using WISE (Web-based Science Environment, Linn & Hsi, 2000). WISE is an integrated set of ...
