Nannostratigraphy and palaeoecology of Shurijeh - Tirgan formations in Kalat and Mozduran sections (East of Kopeh – Dagh).

Abstract

       Abstract   Calcareous nannofossils from boundary of Shurijeh and Tirgan formations at Kalat and Mozduran sections have been studied. These sections were situated in the East of Kopeh-Dagh Basin.In this study 22 nannoplankton species of 15 genera in Kalat section and 20 species of 14 genera in Mozduran section were identified. According to the last occurrence of index species and fossil assemblages calcareous nannofossil biozone (CC5) of Sissingh (1977) has been recognized . Based on this biozone, age of this boundary at kalat and Mozduran sections is Late Hauterivian-Early Barremian.
