Heavy Mineral Distribution and Geochemical Correlation in Bampour River Sediments, Southeast Iran: Implications for Sediment Provenance and Mineral Exploration

This study investigates the spatial distribution and mineralogical composition of heavy minerals in the Bampour River, Iran, with a focus on their economic and geological significance. The study area, located within the Nehbandan-Khash zone, comprises rock units ranging from the Upper Cretaceous to the Quaternary period. Systematic sampling was conducted, with 12 riverbed sediment samples analyzed using techniques such as X-ray diffraction (XRD) and scanning electron microscopy (SEM). Data processing and statistical analysis, including GIS and SPSS software, revealed significant correlations between mineral groups. The iron-bearing minerals showed a strong association with altered and basic rock groups, while ore-bearing minerals correlated with titanium and carbonate groups. Notably, magnetite accounted for over 90% of the total magnetic mineral content, and garnet was identified as a semi-precious gemstone. Additionally, high concentrations of zircon and sapphire were detected in specific samples. These findings enhance the understanding of mineral dispersal in fluvial environments and offer valuable insights for regional mineral exploration and economic prospecting
