چکیده

مقطع مورد مطالعه در جنوب ایران، کوه بانش رخنمون دارد و شامل آهک، مارن و لایه چرتی همراه با فرامینیفر های پلانکتونیک، رادیولاریا و آمونیت می باشد. برای اولین بار به صورت سیستماتیک فرمهای آزاد فرامیینفرهای پلانکتونیک از شیل های تیره و مارن ها ی داریان زیرین استخراج و مطالعه گردید. بیو استراتیگرافی فرامینیفرهای پلانکتونیک در مقطع مورد مطالعه سن آپسین زیرین- ابتدای آپسین بالایی را نشان می دهد. این زمان معادل زمانی حادثه بی هوازی اقیانوسی در حوضه های تتیس است .
حادثه بی هوازی اقیانوسی بطور گسترده ای با مواد آلی بالا مشخص می گردد. نتایج آنالیزهای ژئوشیمیایی در ناحیه مورد مطالعه در بخش زیرین سازند داریان کربن آلی بالایی را نشان میدهد. فراوانی فرامینیفر های پلانکتونیک، رادیولر ها و کربن آلی بالا در بخش داریان زیرین بیانگرمواد غذایی بالا و گرم شدگی اقیانوسی در زمان کرتاسه زیرین است. با توحه به سن توالی مورد مطالعه، کربن آلی بالا و فراوانی فرامینیفرهای پلانکتونیک در شیل های تیره بیانگر حادثه بی هوازی اقیانوسی در ناحیه است . نتایج فسیل شناسی و ژئوشیمیایی ناحیه موردمطالعه یک دیدگاه جدیدی را برای پالئوژئوگرافی حوضه تتیس و توالی های جهانی مطالعه شده فراهم می کند.
