Abstract

The Lower Palaeozonie sequence is well-exposed in Kuh-e-Saluk, 2km, northern Ghelli village. In ascending stratigraphic order, this sequence has been divided into Mila (591m), Lashkarak (250), Ghelli (1140m) and Niur (160m) formations. Although this investigation has been carried out on other palynomorph groups, but my attention has been made on Scolecodont micro fossils. Therefore, 200 surface samples were selected from the Lashkarak, Ghelli and Niur formations. These were treated in the palynological laboratory of exploration directorate of National Iranian Oil Company. Fortunately, all samples contain well-preserved and abundant Scolecodont microfossils. In this study a total of 17 species were encountered that they have good abundancy and I should say that this study is focused only on Niur Formation. Three Scolecodont biozones were established in this area. The zones 1 and 2 occur in the Ghelli Formation, indicating the Middle and Late Ordovician age and zone 3 occurs in the Niur Formation and suggeste the early SILURIAN age (Llandovery) for Niur Formation. They are consistant with those of acritarch biozones (Ghavidel-Syooki, 2001). Among the established families belong to the SCOLECODONTS, two families of Polycheataspidae and Paulinitidae have more genera and species rather than other families. (the Paulinitidae family is studied in another paper). The critical Scolecodont species from Niur Formation in this study are: Atraktoprion cf. eomutus, Kalloprion ef. triangularis, Protarabellites ef. staufferi, Protarabellites ef. reetangularis, Polyehaetaspis cf. wejstropi, Polyeheataspis cf. gadomaskae, Kallioprion sp. , Moehtyella sp. , ... etc.The encountered Scolecodont genera and species were compared with those of contemporaneous strata from Sweden, Poland, Italy, Estonia and the United States of America. This comparison reveals broad similarity between above mentioned countries. Therefore, the Scolecodonot microfossil can be applied as a useful tool for BIOSTRATIGRAPHY and Palaeogeographical concepts.
