چکیده

آثار فعالیت­های نوزمین­ساختی 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 داده­های گسل-خش لغزش تحلیل تنش دیرین با روش وارون­سازی انجام شده است. برای این منظور اندازه­گیری داده­های گسل-خش در 12 ایستگاه مختلف در امتداد این گسل و در پرتگاه­های گسلی صورت گرفت. نتایج حاصل از این تحقیق در تطابق با حرکات امتدادلغز راستگردی این گسل در کواترنر، نشانگر حرکات مورب لغزی این گسل در گذشته و در طول فعالیت آن است.
