Microbiostratigraphy of the Lower Cretaceous strata from the Bararig Mountain, SE Iran

Abstract

The Barremian-Aptian sediments in the Bararig section (Southwest of Kuhbanan) consist of an alternation of marl and limestone. The palaeontological analysis led to identification of twenty seven taxa of benthic foraminifera and algae in the section studied. Diverse assemblages of benthic foraminifera and also the low planktonic/benthic (P/B) ratio show that the sedimentary environment in the study area was oxygenated and shallow.
