This study provides a multi-disciplinary overview of the seismology and geodetic data with tectonics analysis in order to provide an evaluation stress trajectories, probabilistic fault rupture hazard assessment. Based on different scenarios obtained from comparison several overviews their interpretation, we investigated kinematics active structural zones. In this study, magnitudes directions se...
this paper presents evidence on mesozoic inversion of basin bounding faults within the taleqan-gajereh-lar paleograben (tglp) in central alborz range. for this purpose, well documented stratigraphy data across the tglp together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. the tglp has evolved through the early and mi...
سازند آب تلخ یکی از مهمترین واحدهای کرتاسه بالایی در شرق حوضه کپه داغ (شمال شرق ایران) است. سازند آب تلخ در برش مورد مطالعه 833 متر ضخامت دارد و لیتولوژی آن شامل شیل، مارن، سنگ آهک ماسه ای، ماسه سنگ آهکی و شیل می باشد. مرز زیرین سازند آب تلخ با سازند آبدراز پیوسته است اما مرز بالایی آن با سازند نیزار بصورت ناپیوستگی فرسایشی است که با یک افق 3 تا 5 سانتی متری از خاک قدیمه همراه می باشد. 113 نمون...
the present study carried out to identify neo tectonic activity of the gorgan river basin in golestan province, in north of eastern alborz range is investigated by four geomorphic indices including the streamâ gradient index (sl), drainage basin asymmetry (af), reveres symmetry of topography (t) and mountain front sinuosity (smf). result from the analysis is accumulated and expressed as an in...
We studied the behavior of earthquake network using HEALPix spherical pixelization and square cells methods. In first method, geographical region is divided into isolatitude rhombic-spherical same areas method. second we equal cells. To construct a network, if an happens in cell, that cell will become node, two nodes be connected with edge for successive events. The built from Iran’s seismic da...
Background: Nitrate is one of the most important pollutants that is accumulated mainly due to unbalanced fertilizer use and excessive use of nitrogen fertilizers in plant organs. Most of the nitrate in our body comes from vegetables. In Iran, tomatoes and cucumbers are consumed vegetables in the food basket of people. Therefore, the study of nitrate pollution in these products and the identific...
