آثار فعالیت های نوزمین ساختی گسل شمال تبریز به صورت انواع مختلف نشانگرهای تکتونیک فعال در طول پرتگاههای آن قابل مشاهده است. در این پژوهش ابتدا گسل شمال تبریز به سه پاره اصلی و بر مبنای پارامترهای ساختاری و لرزه زمین ساختی پاره بندی شده است. سپس وضعیت تنش دیرین مورد بررسی قرار گرفته و میدان تنش دیرین بازسازی شده است. پس از گردآوری داده های گسل- خش لغزش تحلیل تنش دیرین با روش وارون سازی انجام شده...
Numerical models based on linear elasticity theory predict asymmetric slip distribution with a steep slip gradient near the line of intersection of intersecting normal faults. They also predict a discrepancy between the direction of slip on the fault plane and the direction of resolved shear stress. Both variations in slip magnitude and direction are due to mechanical interaction between the fa...
Dasht-e-Arjan is a northeast trending graben located 65 km west of Shiraz. It was formed along active segments of the Korrehbas fault, perpendicularly to the Shahnesh in and Salamati anticlines. Oriented sampling from bordering fault planes and striations was carried out to evaluate the relative amounts of paleostress/strain needed to form the graben. Measurements of e-twins and c-axis of calci...
We analyzed the bathymetric data obtained during cruises on German research vessel “Sonne” using multibeam echosounders within framework of Russian-German projects KALMAR (cruise SO201-2, 2009) and BERING SO249-2, 2016) in Komandorsky Basin Bering Sea. Detailed maps Piip submarine volcano were constructed. New morphological features its summit edifices their age relations are described, hydroth...
Paleostress plays a significant role in controlling the formation, accumulation, and distribution of reservoirs, this could be an important factor production hydrocarbons from unconventional reservoirs. In study, we will use 3D seismic reflection data to perform slip-tendency-based stress inversion determine field basement northern slope area Bongor Basin. The dataset for technique is easily av...
