بررسی وضعیت تنش در محدوده پهنه گسلی سیاه چشمه- خوی (شمال باختر ایران) و ‏استفاده از روش تحلیل جدایش تنش‌ها در جدایش تنش‌های نوزمین‌ساخت از تنش‌های ‏دیرین

In the present study, the state of stress in siahcheshme-khoy fault zone area in the north-west of iran has been analyzed based on the ‎systematic inversion of focal mechanisms of earthquakes, and fault slip data, to characterise the stress regime controlling‎‏ ‏of most faults and ‎earthquakes in this area. the calculated average stress regime in this area indicates major nw-se trending compression which dominates ‎stress regime in strike slip mode with an intermediate stress axis, ?2, close to vertical. reconstructed stress has shown that average ‎seismotectonic stress and average stress obtained from fault slip data do not have consistency due to of the multi stress regimes in this fault ‎zone. nonetheless stress separation analysis results for fault slip data and earthquake data have good consistency and their first and second ‎analyzed stress regimes have the same trend. also comparison between the results of the stress separation analysis between fault slip data ‎and earthquake data, has shown that the second and third stress regime of this analysis are neotectonic stresses that controlling this fault zone ‎movements. the forth stress regime also is a neostress regime that has been shown in seismotectonic stress separation analysis also, but it ‎seems related to the deep faults. the first stress regime that have resulted from stress separation analysis of both field and earthquake data, it ‎seems a paleostress regime which is not shown in seismic data analysis. also reconstructed stresses in this study, have good consistency with ‎the latest studies in this area especially with geodetic studies.‎
