Ophiolitic rocks in the southeastern part of the Zagros Orogenic Belt can be separated from southwest to northeast, into two groups: the Neyriz ophiolites and the Naien–Shahrebabak–Baft ophiolites. The southeast sector of Sanandaj-Sirjan wasdelimited by the two nearly synchronous ophiolitic belts in its southwestern and northeastern margins. In this study, new ophiolitic formation models were u...

The flexural bulge in central India resulting from India's collision with Tibet has a wavelength of approximately 670 km. It is manifest topographically and in the freeair gravity anomaly and the geoid. Calculations of the stress distribution within a flexed Indian plate reveal spatial variations throughout the depth of the plate and also a function of distnace from the Himalaya. The wavelength...

Earthquakes in India are caused by the release of elastic strain energy created and replenished by the stresses resulting from India’s collision with Asia. Accumulating strain distorts the surface of the Indian plate, which despite its slow development can now be detected using precision geodesy. The largest and most severe earthquakes occur on the boundaries of the Indian plate to the east, no...

1. Introduction This paper proposes beam scan by moving dielectric blocks mechanically in the feed waveguide of single-layer slotted waveguide arrays as shown in Fig.1. Millimeter-wave antennas with beam scan are desired in various systems such as collision-avoidance car radars [1-3]. Electrical scanning is the best but mechanical one is still attractive in terms of cost, efficiency, heat-radia...

The shock wave damage during explosive welding has not been reported in a flyer Mo plate of the Mo/Cu clads. However, it would be an inevitable problem group VI elements. This study was aimed to characterize plate, that is less brittle than W welded Cladding at low horizontal collision velocities leading high angles expected enhance damage, and clads resulted elongation bending tests. On other ...

This paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. Axial bearing analysis is done numerically using nonlinear finite element code LS-DYNA. In this analysis, changes of two main parameters including measure of energy absorp...

The continental collision and subduction between the North China Craton Yangtze Plate resulted in complex multistage tectonic episodes of Tanlu fault zone. To adequately understand geodynamic processes collision, we construct a high-resolution shear-wave velocity model crust uppermost mantle using full-wave ambient noise tomographic method based on new broadband dense seismic array across Our r...

in the urumieh-dokhtar volcanic zone, there are nearly parallel faults to the zagros zone.they were formed during collision of the arabic plate with central iran plate. the northwest-southeast trending of qom-zefreh fault system has long been recognized as major faults in central iran. the general aim of this research is to identify the activity period of this fault and the extent of its effect...
