Volume 24, Issue 94 , March 2015, , Pages 65-72

https://doi.org/10.22071/gsj.2015.42576

Abstract
  In this research, the Campanian -Maastrichtian deposits in Jupar section, Central Iran have been studied to determine biozonation and Paleobathymetry of the deposits. The planktonic and benthic foraminifera were studied in order to assign palaeobathymetry of the Campanian- Maastrichtian deposits. A depth ...  Read More

Microbiostratigraphic Study of the Gurpi Formation at Kuh-e Khaneh Kat (East of Shiraz)

M. R. Esmaeilbeig

Volume 21, Issue 84 , December 2012, , Pages 31-36

https://doi.org/10.22071/gsj.2012.53953

Abstract
  The study of planktonic foraminifera of the Gurpi Formation at Kuh-e Khane Kat (east of Shiraz) led me to find standard biozones from Early Santonian to Middle Campaninan. Four biozones were determined: biozones I (Dicarinella asymetrica zone) and II (Rosita fornicata zone) belong to Early and Late Santonian. ...  Read More
