    Abstract
    Comparative studies on manganese nodules from two different areas (S and R) in the Central Indian Basin show distinct variations in their composition, grade (percent Ni + Cu), and abundance (kg/m2), which are explained in terms of various genetic processes. The results indicate that the nodules from siliceous sediments approximate the diagenetic end members of the series, as described in the Pacific, and are similar in composition to the north equatorial Pacific ore grade nodules. Siliceous sediments in CIB offer the possible sites for first generation mining, where nodules having a mean concentration of percent Ni+ Cu 2.27% at 1.8% Ni + Cu cutoff, and 5 kg/m2 abundance are recovered
