Abstract

Jurassic deposits are well spread in the north of Karim Abad village, north of Bahabad, Central Iran. These deposits contain 41 species of palynomorphs in which there are 15 spore species (12 genera), 15 pollen species (10 genera), and 10 species of cyst of dinoflagellate (three genera). Vertical distribution of miospores and cyst of dinoflagellate, and the first observed occurrence (FOO) and the last observed occurrence (LOO) of selected taxa allow erection of two biozone: Klukisporites variegatus-Chasmatosporites apertus Interval zone and Nannoceratopsis triceras-Nannoceratopsis gracilis Assemblage zone. The relative abundance of dinoflagellate cyst, spore, and pollen is 86. 21%, 7. 2%, and 6. 6%, respectively. Based on relative abundance of miospores’ parent plant fossils, ferns, cycads, and conifers are 37%, 31. 5% and 11. 82%, respectively, and related sporomorph ecogroups (SEGs) indicate that they occurred in different environments such as upland, wetter / drier lowland, river and coastal with temperate-sub-tropical and humid climate. Furthermore, based on the absence of coals in the Hojedk Formation and the high relative abundance of dinoflagellate cysts, it can be concluded that the shallow sea water was prominent here and spores and pollen were transported and sedimented there.
