[email protected] ABSTRACT Three sections of the Oligocene-Miocene Asmari Formation, crossing central and north-central Zagros foreland basin in SW Iran, were measured and studied in order to interpret the biostratigraphy, paleoecology (based on distribution of benthic foraminifera) and diagenesis. Forty-three foraminifer genera and species were encountered in the studied areas and the following assemblage zones have been defined: 1) Nummulites vascus-Nummulites fichteli, 2) Lepidocyclina-Operculina-Ditrupa, 3) Archaias asmaricus-Archaias hensoni-Miogypsinoides complanatus, 4) Miogypsina-Elphidium sp.
