Time and place of progressive regional metamorphism: A repley to N. D. Chatterjee
Misreading of some published papers has led Dr. N. D.Chatterjee to erroneous conclusions about the local geology in the Ghatsila area in Singhbhum, eastern India, and his doubts regarding the metamorphic history deduced by the author here are therefore unjustified. The stratigraphy and structural geometry in this terrain are not at all debatable, and the evidences for a progressive metamorphism broadly contemporaneous with folding and preceding thrusting are incontrovertible. To take any particular metamorphic terrain, whether Simplon or Singhbhum, as the prototype of regional metamorphism is as yet premature.
