abstract="Upper Permian deposits of Shorjestan area, central Iran included marly limestone, red to amethystine limestone with layers of red, green and gray shales followed by lower Triassic deposits as continuous with dark shale lithology, marly limestone, red and green shales and igneous rocks. In studied sequence there are terrestrial and rarely marine palynomorphs with low varieties and frequencies and fair preservation. Hambast Formation deposits are attributed to Upper Permian on the basis of stratigraphic distribution of some palynomorphs such as Florinites balmei, Alisporites nuthallensis, Vittatina lata, Laevigatosporites ovatus. Aforementioned palynoflora are common with some parts of Saudi Arabia Upper Permian palynoflora (OSPZ6 assemblage zone, Changhsingian). Regarding mass extinction of end-Permian and disappearance of most vegetation and lack of time for recovery, it may find palynoflora with low varieties such as Alisporites sp., Falcisporites sp. and fungal spores in lower Triassic deposits of studied section. Notable frequencies of fungal spores and plant tissues in lower Triassic deposits probably are related to vegetation disappearance in boundary of Permo-Triassic (PTB) and aggregation of corruptible organic matters.<p />",
