Biostratigraphy of Late Devonian Conodonts in Gerik Section, Eastern Zarand, Kerman Province

The Bahram Formation equivalent sequence in the Gerik section (eastern Zarand) displays middle Frasnian to early Famennian age on the basis of conodont investigation. Twenty-eight species and subspecies were identified. Seven biozones were recognized on the basis of vertical distribution of these taxa along the stratigraphic column; older than Upper hassi Zone, Upper hassi – jamieae zones,? Lower rhenana Zone, Upper rhenana – linguiformis zones, Lower triangularis, Middle triangularis - Lower crepida zones, Middle – Upper crepida zones. Index conodont species those are recovered the biostrome horizon in the lower part of section proved the middle Frasnian age (Upper hassi – jamieae zones). view of conodont fauna, lithostatigraphy and age; the Gerik section is comparable with other successions of the Bahram Formation in Kerman, Tabas and Esfahan areas and shows a shallow sedimentary environment.
