The Study of Techniques Calcareous Nannoplanktone in Area Kope-Dagh With Light and Electronic Microscope

In this research, Kope-Dagh area (Khangiran formation.), some 25 km of Shorlogh village, north-east of Iran was investigated. Many researchers have paid their attention to the area that is economically important due to gas reservoirs. To explore the area, characteristic light microscope (LM) and scanning electron microscope (SEM) were employed to study the calcareous nanofossils. Based on the first occurrence and fossil assemblages, nine biozones were recognized. These assemblages, from the base to the top, are NP13-NP24 (Martini 1971) and CP11-CP19a (Okada & bukry 1980). The age of Late Early Eocene to Late Oligocene is suggested for Khangiran section.
