Abstract:

The main aim of this research is study of the planktonic foraminifera morphogroups distinction genus to perform by changing the umbilicus area in Ziarat-kola section to find novel results. Therefore, original objection at this research considers the cause of organizing umbilicus structures (Lip, Portici, Tegilla) at this protests. it seems that phylogeny trend entirely the changes of planktonic foraminifera changing from lip at primary morphogroup to tegilla at development shape which continued this phylogeny trend opening become entirely umbilicus that this trend accompanied to increasing deep. Therefore, the study of planktonic foraminifera morphotype, and recognizing, the obtained results from planktonic foraminifera analysis percent and their comparison with umbilicus structures area diagrams at this section indicats the increasing morphotype three accompany with increase in sea level that here dominated portici and tegilla structure with compressed opening and with decrease of morphotype three which showed decrease sea level, opening structure (lip) dominated. These trends follows the from Pascal law at Ziarat-kola section of the research.
