Abstract
The present study reports the magnetic susceptibility study of Late Maastrichtian sediments (Kallamedu Formation) of Anyalur Group The Nimyur section exhibits two types of susceptIbility pattern Ie C-zero and C4 The susceptibility pattern of this sectIon fits well with the patterns observed In the mterval of Upper Cretaceous part of the reversed interval (29R) The K/T boundary has been fixed above the C-zero peak 10 most of the studied sections around the world We suggest that the K/T boundary should be placed above the Nimyur section, based on the characteristicc magnetic susceptibility pattern.
