A succession of Late Campanian- Early Maastrichtian is analyzed from Gurpi Formation with regard to the calcareous nannofossils. Correlation Matrix was applied for the first time to the entire nannofossil assemblage to reconstruct environmental conditions. A detailed quantitative calcareous nannofossil analyses is performed on samples in order to further investigate the climate events, and inte...

this study presents the nannostratigraphy and nannofossil events in the lower boundary of kalat formation in the east and west of the kopeh- dagh basin. the kalat formation comprises of coarse grained detritus limestone with subordinate sandstone intercalations. in the current study, six sections have been chosen in the east and west of the basin which are as follow: dobaradar section, kalat se...
