Title

Biostratigraphy of Mesozoic-Cenozoic boundary based on calcareous nannofossils in Bulfars section, Southwest Iran

Pages

  1-9

Abstract

 To study Mesozoic – Cenozoic boundary based on calcareous Nannofossils, section of Tang-e-Bulfars in East Ramhormoz was studied. The fossil groups in determining the relative age of the Mesozoic and Cenozoic layers are important. In this interval, a thickness of 32 meters of shale and limestone were studied and for the first time 35 species of Nannofossils were identified. As a result, the identified biozones includes Reinhardtites Levis Zone (UC18/CC24) and the base of Arkhangelskiella cymbiformis (CC25/UC19) with Late Cretaceous age and Heliolithus kleinpellii Zone (NP6) with Selandian/Thanetian age. Based on the identified zones, the transition period of Early Maastrichtian-Selandian/Thanetian and the boundary between the Cretaceous to Paleogene was determined as a discontinuity. The presence of index species of calcareous Nannofossils indicates that the studied sediments in the section of Tang-e-Bulfars were deposited in the lower latitudes and under warm climatic conditions.
