英文摘要	In the present study, the Lower-Middle Pliocene Cheleken Formation in the south of Ghaemshahr city was studied to determine the provenance of the comprising sediments, paleoclimatic conditions, and tectonic setting of the rocks. Petrographic and geochemical analyses of major and minor elements of the samples were used for this purpose. This Formation is composed of three major facies including conglomerate, fine sandstone, and mudstone. The source formations which were recognized to be supplying sediments to the Cheleken Formation depositional basin include Lalun, Ziarat, Tizkuh, Dalichai, and Cretaceous formations. According to the discrimination diagrams and other ratios for minor elements of the studied samples, a complex of felsic to intermediate igneous rocks in the source region was deciphered. The depositional environment of the rocks experienced humid and semi-arid climatic conditions during deposition. According to the CIW index, the samples underwent a high level of weathering (97%) in the source area or during transportation. From a tectonic point of view, the Cheleken Formation was deposited in an Active Continental Margin setting.
