Abstract

Kashafrud Formation in the Navia section (59 km west of Bojnourd) with 749 meter thickness is composed of silici-clastic sediments. In this study, based on nanofossils genus Watznaueria  britannica and ­Cyclagelosphaera  margerelii  that were recorded at 350 and 710 meter  above the base of formation revealed that the age of this interval can be Bajocian-? Bathonian. The fragments and feldspar are the most important constituents. Three sandstone petrofacies, including subchertarenite, chertarenite, phylarenite and feldspatic chertarenite, are identified. Modal analysis of sandstones, plotted on QmFLt and QtFL diagrams, show that the sediments of Kashafrud Formation are located on the recycle orogeny. However, geochemical studies for identification of source rocks revealed these sediments may have been derived from intermediate igneous and sedimentary rocks. CIA Index (chemical weathering), high average Plagioclase index of alteration (PIA), ICV (index for determining the type of mature and immature source rocks) as well as SiO2 versus Al2O3 + K2O + Na2O show a warm and semi humid climatic conditions. Using ternary diagram (Na2O+ K2O), (TiO2+ MgO+ Fe2O3), (SiO2/20) is also proved that these sandstones may have been deposited on a passive continental margin setting.
