Hegde (1985, 1989) has himself modified his earlier view and suggested that the Ahar artifacts were possibly made from the nearby region of the Aravalli which constitutes of not-too-hard tremolite-chlorite schists rather than the far-off Khetri ore embedded in quartzite rocks, hard and less easily extractable. While impurity patterns of the ores in different parts of the Aravalli 'may be similar' (the previously stated Ahar-Khetri correlation now loses much of its significance), the lead isotope ratios markedly differ in the north-eastern, central, and south- western parts of Aravalli (Hegde, 1985). Efforts are in progress to correlate metal artifacts and specific ore deposits through lead isotope ratio analysis.
