This should not be regarded as a solution to the chromite exploration problem, however, because again serpentine is a dominant complicating factor. Yungul (1956) considered magnetics less useful in exploring for chromite than gravity due to the high variability of the serpentinization. Bhattacharyya and others (1969) thought that the magnetic ...
