Abstract

Introduction: The Kopeh-Dagh sedimentary basin formed after the middle Triassic orogeny in northeastern Iran. There is no evidence of major tectonic activity in this region; all formations are conformable, except for a few disconformities within the Cretaceous succession (Afshar-Harb, 1994). The lower contact of the AB-DERAZ FORMATION in Sanganeh section with the Aitamir Formation is paraconform, and the upper contact with the Ab-Talkh Formation is conform. This section of the AB-DERAZ FORMATION is about 300 meter thick. In this section, lithology is composed of light gray shale, olive green shale and three chalky limestone bands. SEQUENCE STRATIGRAPHY can be used to interpret the sea level fluctuations during deposition of any stratigraphic succession. The new method of PALYNOLOGICAL FACTORS, such as biological degradation of palynological particles, roundness and homogeneity of equidimensional phytoclasts, the relative abundance of opaque phytoclasts to transparent phytoclasts, the relative marine palynomorph to terrestrial particles ratio, relative abundance and diversity of dinoflagellate cysts and relative chorate to proximate, proximochorate and cavate (C/PPC) morphotype ratio can be use for interpretation of stratigraphic sequences (Schioler, 2002). In this study, these factors were used for differentiation of sequences.
