Sedimentary geochemistry of the sedimentary facies of the Qom Formation in the southwest of Saveh

Summary In order to study the sedimentary geochemistry of the  detrital facies of the Qom Formation in the southwest of Saveh (in the study area in the 100,000th Formehin map) in the deposits of the Qom Formation and to study the amount of major and rare elements (including strontium, manganese, calcium, etc.) in Section that are similar in age and the changes of chemical elements during the sedimentary sequence in order to understand their sedimentary conditions, 28 rock samples were selected from the two regions AB and CD, and 12 samples were selected from the existing samples to identify the tectonic position and tectonic function separator diagrams. and the identification of the origin of sandstone sediments, as well as the separation of calcareous sandstones, calcareous shales, limestones, and calcareous wares were examined.
The result shows the tectonic position of the Qom formation in the passive margin pattern and the origin of sandstones and sedimentary units in the studied area is quartz-bearing sedimentary rocks, it can also be concluded that the origin of sandstones is mainly a subgroup of calcareous sandstones
