Geomorphological Approach to the Charnockite Problem

Charnockitic rocks, although formed at great depths, are found at the present day occupying the highest plateaus and peaks in the Peninsula, Evidences are put forward to indicate that the present position of charnockites is the result of faulting and repeated uplift. It is thought that 'intrusion' into upper levels of the earth's crust would destroy the characteristic features of deep seated plutonic metamorphism shown by charnockites. The continued presence of these characteristics without change irldicates that the present position of charnockites is the result of uplift and not intrusion. Charnockites are present only in regions of repeated uplift.
