Abstract

In this study biostratigraphy of the Upper Cretaceous deposits (Gurpi Formation) in Sepidan section located in the Interior Fars basin (SW Iran) was studied. The Gurpi Formation in this section consists of 360 m lime shale, argillaceous limestone and shale laid continuously on the Ilam Formation and with a paraconformity under the Pabdeh Formation. Nine genera and 27 species of planktonic foraminifera have been identified in the section. On this basis, the Gurpi Formation here includes nine biozones with an age of Santonian to Maastrichtian. The biozones identified resemble considerably those of the other parts of the world.

Abstract [Persian]

در این تحقیق زیست چینه نگاری نهشته های کرتاسه بالایی (سازند گورپی) در فارس داخلی (برش سپیدان) مورد مطالعه قرار گرفته است. سازند گورپی در برش سپیدان از 360 متر شیل آهکی، آهک رسی و شیل شکل گرفته است که به صورت پیوسته به روی سازند ایلام و با یک ناپیوستگی در زیر سازند پابده قرار گرفته است. 9 جنس و 27 گونه از روزن داران پلانکتون در برش سپیدان شناسایی شدند. بر این اساس سازند گورپی در برش سپیدان شامل 9 زیست زون به سن سانتونین تا انتهای ماستریشتین است. مطالعات زیست چینه نگاری این برش نشان می دهد که زیست زون های شناسایی شده در این برش شباهت قابل ملاحظه ای با سایر زیست زون های استاندارد جهانی معرفی شده برای کرتاسه بالایی دارند .
