The above data clearly suggest cultural contacts between the three nuclear zones and indigenous diffusion of iron technology from one zone to another. The remote possibility of Sialk VI iron-making tradition (which flourished only after 9th century B.C.) influencing the whole of India through the immigrant Aryans (Banerjee, 1965) may be safely ruled out. There are enough evidences of early experimentation, imperfect solid-state reduction, wastage of iron in the slag etc. in the sites of each of the three nuclear zones to justify the theory of indigenous origin.
