Title: Structural relations of charnockites of South India
Abstract: The structural features of the Peninsular gneisses were discussed and compared with those in the charnockitic rocks. On this basis, three types of charnockite occurrences can be recognized: those involved in isoclinal folds that were later boudinaged and refolded, those affected by migmatization synkinematic with early isoclinal folding, and incipient charnockites formed in low-pressure zones of fold-hinges and boudin-necks (e.g., Kabbaldurga). It was concluded that at least two, if not three, stages of charnockite formation are required by these structural data.
