چکیده

      در این تحقیق، تحلیل های آماری توزیع طولی، فراوانی و تراکم طولی گسل های منطقه زاگرس  و الگوهای مکانی این متغیرها انجام گرفته است. نتایج این بررسی ها نشان داد که توزیع طولی گسل ها از قانون توانی با ضریب توانی 29/1 و توزیع تجمعی گسل ها نیز از تابع نمایی پیروی می کند. توزیع طولی و توزیع تجمعی طولی گسل ها در 4 دسته، نتایج مشابهی را به جز برای دسته اول نشان می دهد که مؤید آن است که به جز دسته اول، گسل های دیگر در یک میدان تنشی تقریبا مشابه از لحاظ جهت به وجود آمده اند. توزیع تراکم گسل ها الگوی یک تابع نمایی را نشان می دهد در حالیکه تراکم طولی آنها تابع توزیعی خاصی را نشان نمی دهد. در عین حال توزیع تجمعی فراوانی و تراکم طولی نشان دهندهشکل گیری گسل های جدید نسبت به رشد و افزایش طول گسل های اولیه است.
