Abstract

IN India, the term ‘Archaean’ has been applied to the formations below the so-called Eparchaean unconformity—the unconformity at the base of the Cuddapahs and their equivalents. The importance of the Cuddapahs as a chronostratigraphic unit arises out of this consideration. Investigations were initiated by me to date the galenas occurring in Cuddapahs and related formations. This communication presents preliminary results of the lead isotope studies.
