Abstract The Middle Miocene to Early Pleistocene Siwalik Group is composed of sediments deposited in the Himalayan foreland basin. In this study, the heavy mineral assemblage and chemical composition of detrital garnets from the sandstones in the Lower Siwalik sub-group, which are exposed along the Karnali River in western Nepal and the Tinau Khola in central Nepal, are studied and the provenance shift during the Middle Miocene is discussed. The heavy mineral assemblage in the lower section of the Lower Siwalik sub-group is characterized as predominantly zircon-tourmaline-rutile. Chemical analysis of the detrital garnets showed a monomodal almandine-rich composition with low pyrope (Prp
