Here we present powder X-ray diffraction (XRD) and Fourier transform infrared (FT-IR) spectroscopic data on clay minerals associated with the iridium (Ir)-enriched and fullerene-bearing yellowish-brown clayey layers of the Anjar intertrappean beds, Kachchh district, Gujarat, India. The objective is to understand the role of clay minerals composition in preserving the fullerene molecules and Ir contents in the Anjar intertrappean beds. XRD patterns show the presence of smectite along with palygorskite and sepiolite. FT-IR spectra also confirm the presence of these Mg-rich clay minerals and broadened peaks indicate their nanocrystalline nature. The study shows a correlation between the nature of smectites and the occurrence of fullerenes and iridium
