  In this research, the microbiostratigraphy and depositional environmental implications related to the Surgah Formation at the northern flank of the Kuh-e Sepid anticline in the Lorestan Basin are discussed. A study of small planktonic foraminifera from the 101-m-thick Surgah Formation led to the identification of three Turonian–Santonian biozones: (1) Helvetoglobotruncana helvitica, (2) Marginotruncana sigali, and (3) Dicarinella concavata. The age of the Surgah Formation in the study area is determined as Turonian–Santonian. The Surgah Formation overlies the Sarvak Formation and underlies the Ilam Formation in the studied stratigraphic section. Based on an analysis of pelagic foraminiferal assemblages and microfacies features, seven different microfacies have been recognized. These can be grouped into three depositional environments: the inner, middle, and outer ramps. Manuscript profile

  In order to study and inspect of biostratigraphy and lithostratigraphy of Eocene sediments of Haleganwell in folded zagros 100 thin microscopic sections of this well’s samples was studied. Mentionedstudies caused to recognize 12 genus and 25 species of Planktonic foraminifera. According to spreadstratigraphy planktonic foraminifera 3 Biozone (P6, P13, P16/P17) that separated and introduced forEocene sediments in this well by D.Verga & R.Rettori (2003). Subsurface of section stratigraphy iscompared with wynd Biozons (wynd,1965). According to recognized and separated biozons, Wyndbiozonation is included 45, 47, 50. In this essay Pabdeh formation in Halegan well was introduced andcompared both D,Verga & R.Rettori (2003) and Wynd (1965) Biozone. Results of comparison revealsthat the best zonation for Pabdeh formation in Halegan well is D.Verga & R.Rettori (2003) Biozone.Pabdeh formathion is included a sequence of shale, marl, argillaceous limestone layers and their colorsare usually gray, withe-brown in Halegan well. Pabdeh formation had been formed high depth of sea.It is an evidence for depth of zone in this area in Eocene period. According to this studies it seemsHalegan well had been full of water in Eocene period the most onlap of sea had been in this period Manuscript profile

  In central Alborz Mountains in north of Iran, a new Cretaceous-Tertiary boundary (K/T) section near GalanderudMine in Mazandaran province reveals diversity of planktonic foraminiferal the fauna similar to those found inElKef & Elles in Thunisia.The Cretaceous-Tertiary boundary is located by planktionic foraminifera with in a narrow interval bounded bylast appearance of tropical and subtropical Cretaceous species and first appearance of small Tertiary species. InGalanderud section only 5 species survived after the Cretaceous-Tertiary boundary event and 31 species ofCretaceous became extinct in or before Cretaceous-Tertiary boundary. The Maastrichtian species that seem todied out gradually are generally large and cosmopolitan. Manuscript profile
