چکیده

سازند میشان عضو میانی گروه فارس است که در حوضه رسوبی زاگرس در بازه زمانی میوسن پیشین ـ پلیوسن نهشته شده است. برای بررسی ریزرخساره‌ها و بازسازی محیط رسوبی نهشته‌های این سازند در جنوب خاوری حوضه زاگرس، برشی در ناحیه شهدادی انتخاب و مورد مطالعه قرار گرفت. با توجه به مطالعات سنگ‌ چینه ‌نگاری، دو رخساره سنگ آهکی و مارنی در برش تشخیص داده شد. رخساره سنگ آهکی شامل نه ریزرخساره (L1-L9) و رخساره سنگی مارنی دربرگیرنده نهشته‌های سه محیط (MA-MC) است. بر اساس ریزرخساره‌های شناسایی شده، ارتباط جانبی آن‌ها با هم، ترکیب اجزای کربناته و فونای موجود، در محیط نهشته‌های پلاتفرم کربناته از نوع رمپ همشیب با سه مجموعه رخساره‌ای رمپ داخلی، میانی و بیرونی تشکیل گردیده است. در مجموعه رخساره‌ای رمپ داخلی کمربندهای رخساره‌ای پهنه کشندی، لاگون محصور شده و پشته‌های ماسه‌ای، در مجموعه رخساره‌ای رمپ میانی کمربندهای رخساره‌ای لاگون غیرمحصور و ریف کومه‌ای و در مجموعه رخساره‌ای رمپ بیرونی، کمربند رخساره‌ای دریای باز تشخیص داده شده است. بیشترین نهشته‌های برش به ترتیب مربوط به کمربندهای رخساره‌ای لاگون غیرمحصور، لاگون محصور و دریای باز بوده که در سکانس‌هایی عمیق‌شونده به سمت بالا نهشته شده‌اند.
