Abstract :

Sardar Formation consists of sandstones, shales and limestones. The provenance and tectonic setting of siliciclastic sediments of this formation has been interpreted by geochemical methods. The Sardar Sandstones of the east central Iran are probably enriched in quartz and poor in feldspar and lithic fragments and can be classified as quartzarenites, sublitharenites and subarkoses. They are cemented by silica, calcite, dolomite and hematite. Sandstones in the two lithostratigraphic sections have similar chemical composition from a common provenance. In these sandstones, Al2O3 and SiO2 are commonly well negative correlated. The geochemistry of sandstones indicate that the tectonic setting of the study area were passive margin field. Based on geochemical data, a climatic condition during the deposition of these sandstones is semi humid.
