Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and adjacent source regions by analyzing diagnostic visible to shortwave infrared absorption features. Six diagnostic minerals (Calcite, Kaolinite, Musc
