Abstract

Within the Brahmani valley granulite terrane (Eastern Ghats) of Dhenkanal district, Orissa the sporadically outcropping pods of chromite-rich serpentinite are devoid of chrome-poor enstatitite which occurs abundantly in the northern Gorumahisani greenstone terrane as well defined units within the chromite-rich suites at Katpal, Sukinda and Boula-Nausahi, Cuttack and Keonjhar districts. Available field evidence is compatible with a model of emplacement of these ultramafic bodies along the contact between the two terranes in a number of stages involving soft and hard collision, subduction of Gorumahisani Group oceanic lithosphere below the Eastern Ghats granulites followed by delamination and asthenospheric upwelling. Falsifiability tests for the model have been indicated.
