چکیده

  به منظور مطالعه بایوستراتیگرافی سازند گرو در ناحیۀ لرستان مرکزی، یک برش تحت­الارضی در تاقدیس نفت در جنوب کرمانشاه انتخاب و مورد بررسی قرار گرفت. ستبرای حفاری شدۀ سازند گرو در این برش 485 متر است و از نظر سنگ­شناسی از سنگ آهک رسی و مارن خاکستری تیره تشکیل شده است. در این پژوهش در مجموع 1150 مقطع نازک مورد بررسی قرار گرفته است. در مطالعات زیست چینه­ای سازند گرو در برش­ مورد مطالعه ضمن تشخیص 61 گونه متعلق به 17 جنس از روزن­داران پلانکتونی، 9 بایوزون شناسایی و معرفی شده است. بر مبنای گسترش چینه ­ شناسی فسیل­ها و بایوزون­های معرفی شده، سن سازند گرو در بخش حفاری شده برش تحت الارضی چاه نفت آپتین پیشین- سنومانین پیشین می­باشد.

چکیده [English]

In order to biostratigraphy of the Garau Formation in the centeral Lurestan, one subsurface section (Naft well) in Naft anticline, south Kermanshah was selected and studied. The drilled thickness of the Garau Formation in this section is up to 485 meters and lithologically composed of argillaceous limestones and dark gray marls. In this research 1150 thin sections of subsurface Naft well section were studied. In biostratigraphic studies of the Garau Formation in study section 61 species belong to 17 genera of planktonic foraminifera were recognized and 9 biozones were identified. Based on distribution of fossils and biozones identificated, the age of the Garau Formation in drilled part of the subsurface Naft well section is Early Aptian to Early Cenomanian
