To study the Shirgesht Formation biostratigraphy in Kalmard Horst in relation to its conodont content, the Miyugodar
(Miangodar) ~tratigraphic section was selectee which is located in southwest of Tabas city. The Shirgesht Formation in the
mentioned section is mainly composed of silici .Iastic rock units and overlay unconformably on Kalmard Formation (attributed
to Pre-Cambrian) and is overlain by Gachal For nation (Carboniferous). Thirty five rock samples were selected from appropriate
rock units(Shirgesht and Gachal Formation). SImples were studied in laboratory for more details. According to the extracted
conodont from Shirgesht Formation in Miyugodar section, the age of this formation can be regarded as Early Ordovician
(Tremadocian - Arenigian). Three conodont assemblage zones were recognized in Early Ordovician units. They are: Cordylodus spp.. Deltifer and Proteus Global Standard Conodont biozones. The recognized biozones are as followed:
1- Oneotodus - Drepanodus Assemblage Zone
2- Acodus deltatus - Protopanderodus Assemblage Zone
3- Acodus - Oistodus Assemblage Zone
