چکیده

در این مطالعه اثر شکستگی ها بر روی تاقدیسورها که از مهمترین عوامل ناپایداری هستند که باعث ایجاد مخلوط هیدروکربوری در سازند آسماری در فروبار دزفول زاگرس چین شده است ، بررسی گردیده است. به این منظور شکستگی همراه با تاقدیس های کوه آسماری بدون شاهدی از گسلخوردگی (نوع اول) ، کوه سولک متأثر از راندگی در یال پیشانی (نوع دوم) و کوه کمرآب در مجاورت با گسل عرضی ایذه (نوع سوم) مورد مطالعه قرار گرفته است. پارامترهای موقعیت ، فراوانی ، فاصله ، سخت ، تراکم و طول شکستگی ها ، در طول مطالعات میدانی و با استفاده از تصاویر ماهواره بررسی شده است. مقایسه پارامترها در نواحی مختلف تاکدیسورها نشان داد که مرکز شکستگی آنها در موارد مختلف متفاوت است. همچنین نتایج مطالعه نشان داد دادگاه ، نواحی لولایی در نوع اول اول ، پهلوی پیشانی است که توسط گسل طولی در نوع دوم و دماغه جنوب شرقی متشکل است از گلس عرضی در نوع سوم ، دارای بیشترین مقاومت - شکست شکستگی است.
