چکیده

به منظور بررسی ریزرخساره‌ها و محیط رسوبی سازند بهرام در جنوب خاوری انارک، برش چینه شناسی کوه بندعبدالحسین انتخاب و مورد مطالعه قرار گرفت. سازند بهرام در این برش 366 متر ضخامت دارد و سنگ شناسی آن شامل سنگ آهک‌­های نازک تا ضخیم لایه، تناوب سنگ آهک‌­ها و شیل‌های نازک لایه، سنگ آهک­‌های ماسه­‌ای و سنگ آهک­‌های مارنی است. براساس تغییرات رخساره­ای و ویژگی‌های سنگ شناختی 16 ریزرخساره در این برش تشخیص داده شده است. بررسی رخساره‌های شناسایی شده حاکی از ته‌نشینی این ریزرخساره‌ها در یک رمپ کربناته در زمان دونین میانی و پسین است. بررسی­‌های چینه نگاری سکانسی سازند بهرام بر مبنای تغییرات عمودی ریزرخساره‌ها و مقایسه آن‌ها با منحنی تغییرات سطح آب دریا به شناسایی 7 سکانس درجه 4 در برش مورد مطالعه منجر شده است. با توجه به اطلاعات به دست آمده، سکانس­ رسوبی اول و هفتم قسمتی از سکانس­‌های رسوبی می‌­باشند و سکانس‌­های رسوبی دوم تا ششم سکانس‌­های رسوبی کامل و دارای دسته رخساره‌های پیش‌رونده، پس‌رونده، بیشینه سطح غرقابی و مرز­های سکانسی هستند.
