Combined use of band shape algorithm, linear spectral un-mixing on Clementine & Moon Mineralogy Mapper data for identifying the imprints of magmatic differentiation – A study around Aristarchus Plateau

•The study compares the mineral maps derived from Clementine and Moon Mineralogical Mapper data.•Research highlights superiority of M3 data in delineating additional minerals.•Linear spectral unmixing estimates relative abundance of different minerals.•Relative abundance of minerals is used to identify different rocks.•Role of geological structures is hypothesised for the genesis of these rocks.
