Abstract

MIOSPORES retrieved from thirty-four rock samples collected from the uppermost beds of surface section of the CHAMANBID FORMATION at its type section are used to investigate spore-plant relationships. The type section is located about 60 km southwest of Bojnourd and near Chamanbid. This rock unit conformably overlies the Bashkalateh Shale and with a sharp lithological break underlies the Mozduran Formation. Diverse and well preserved PALYNOFLORAS, dominated by terrestrial palynomorphs including 39 species of spores (of 28 genera) and 13 pollen species (assigned to 11 genera), are identified. Other palynomorphs, in descending order of abundance, are dinoflagellates, fungal spores, and foraminiferal test linings. The MIOSPORES are assigned to Filicopsida, Lycopsida, Ginkgoopsida, Coniferopsida, and Bryopsida. Notable abundance, in the Chamanbid PALYNOFLORAS of fern spores viz.: Klukisporites, Cicatricosisporites and Cyathidites is interpreted to imply that the host strata accumulated under moist warm climate during the Tithonian time. This can be seemingly confirmed with reference to co-occurrence of dinoflagellates such as Systematophora areolata, Tehamadinium spp., Cribroperidinium spp. and Kallosphaeridium spp. and fungal spores. Marked relative abundance of Corollina upward in the studied section seems to indicate progressive dominance of dry warm climate towards the Late Jurassic time.
