The variations in Ti content of ortho- and para-metabasites against their iron enrichment (F) ratios have been shown to separate the two groups of rocks according to their origin. The Ti vs. Mn plots also exhibit a similar relationship. No correlations were obtained in the cases of Se, V, Sr, Co and Ni. It is concluded that the origin of metabasites can be deciphered based on these diagrams. However, field criteria are of much significance in making any definite conclusions.
