biostratigraphy and paleoecology of early miocene deposits in gefriz section (south west of kerman) based on benthic foraminifera
in order to study the biostratigraphy and paleoecology of the early miocene in south west of kerman province, one section (gefriz) has been chosen, measured and sampled. the thickness of measured section is about 67 m. it consists mainly of thin to thick bedded limestone and marl. at this section, the early miocene deposits nonconformably lie between volcano sedimentary eocene at the base, and ...
متن کاملEarly-Miocene Gastropods from Khavich Area, South of Sirjan, (Kerman, Iran): Biostratigraphy, Paleogeography and Paleoecology
A total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the Miocene deposits of Khavich section, south of Sirjan, Kerman. Gastropods assemblage in Khavich area indicates deposition in shallow, warm ramp-type carbonate platform. The Miocene and even Oligocene gastropod assemblages, relatively similar to Khavich section, reported from the othe...
متن کاملBiostratigraphy and paleoecology of Paleogen rocks based on calcareous nannofossil in Kafaz section, east Iran
In this study, the assemblage of calcareous nannofossils has been investigated in long and continuous deposits from a Kafaz section in Eastern Iran. A systematic study of calcareous nannofossils has indicated 39 nannofossils species. In order to the age determination of Kafaz's deposits, a revised zonation for the Eocene is used. Based on it, the Early-Middle Eocene deposits of Kafaz section is...
متن کاملBiostratigraphy and paleoecology of Cretaceous rocks based on calcareous nannofossil in Sarayan section, East Iran
Calcareous nannofossil assemblages recovered from a long, continuous section have been described from the Sarayan region in Lut Block in east Iran. The marine Upper Cretaceous sediments of this section yield medium diverse and well-preserved calcareous nannofossil assemblages. A structural analysis of Upper Cretaceous calcareous nannofloras has revealed 30 nannofossil species. A revised zonatio...
متن کاملcalcareous nannofossils biostratigraphy and paleoecology of the last layers related to eastern alborz cretaceous deposits in cheshmeh gholghol section
coccolithophores are important primary producers in the modern world ocean and were almost certainly important in the mesozoic oceans, prior to the evolution and rise of diatoms in the phytoplankton. calcareous nannofossils are abundant, planktonic, rapidly evolving and largely cosmopolitan, so they are a good tool for biostratigraphy and paleoecology studies especially in the cretaceous system...
