Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...

Abstract The structure and tectonic evolution of the Cretaceous rift basins southern Egypt are poorly understood. In this study, tectonostratigraphy Komombo Basin has been determined using seismic, well biostratigraphic data. basin is compared to Kharit, Nuqra Beni Suef in as Muglad Sudan. a 58 km long, 28 wide NW–SE trending half‐graben infilled with 2200 m Berriasian‐Maastrichtian sediments o...

Hydrothermal activity on mid-ocean ridges plays an important role in shaping marine chemistry, yet the variability of hydrothermal venting and its forcing mechanism remain elusive. Here, we analyzed a sediment core obtained near tectonic-controlled Tianxiu vent field, Carlsberg Ridge, to reconstruct history. The documented two significant events (H1 H2) past 30 ka. H1 occurred at 24.1–24.5 ka d...

in central part of kopeh dagh there is an array of active right-lateral strike-slip faults that obliquely cut the range and produce offsets of several kilometers in the geomorphology and geological structure. geomorphic indices indicate the presence of differential uplifting in history of this area. tectonic activity of the study area is investigated by a large number of dem derived catchments ...
