Abstract: (4033 Views) |
The oceanic facies in the Southwest of Iran (Neo-Tethys), deposited between Iranian and Arabian blocks. In this study, the part of this oceanic facies have been investigated in the upper part of the Gurpi Formation and lower part of the Pabdeh Formation at Shalou section, located in southeast of Izeh. In this section, the Gurpi Formation is mainly composed of green and dark gray shale and lower part of the Pabdeh Formation consists of purple shale. For introducing index species, calcareous nannofossil assemblages and bio-zones, 82 slides have been studied at the facies which led to the recognition of nine bio-zones. As a result, 41 species and 27 genera of calcareous nannofossils According to the identified bio-zones, the age of studied section is late Maastrichtian to late Paleocene (Thanetian) and K/Pg boundary is continuous at the studied interval, that is corresponding to CC25 - CC26 , and subsequently NP1- NP7/NP8.
