TY - JOUR ID - 31517 TI - B IOSTRATIGRAPHY OF SARAKHS (N.E. IRAN) AND NAFTE- SHAHR (N.W. IRAN) SECTIONS JO - Journal of Sciences, Islamic Republic of Iran JA - JSCIENCES LA - en SN - 1016-1104 Y1 - 1992 PY - 1992 VL - 3 IS - 2 SP - EP - DO - N2 - It is the first time that biostratigraphic zonations of calcareous nannoplankton from Maestrichtian to Lower Tertiary deposits of Iran are reported. The required samples from the north-eastem and western parts of the country were selected from the stocks of the National Iranian Oil Company. Taxonomic descriptions were not the main objectives, although a new species and genus are apparently present in the assemblages. The main purpose of this study is to establish the biostratigraphic zonations and correlate them with the universally accepted standard biozones. Both petrographic and scanning electronic microscopes were used in this investigation UR - https://jsciences.ut.ac.ir/article_31517.html L1 - https://jsciences.ut.ac.ir/article_31517_e0e870bca8e7c4d44ead707a766c6810.pdf ER -
