Abstract

Geochemical, geochronological, palaeomagnetic and palaeontological evidences that show that the third Intertrappean bed at Anjar encompasses the Cretaceous-Tertiary boundary are described. Presence of three well separated iridium rich horizons indicates multiple depositional events. Their origin in volcanic or multiple cometary impacts is discussed. The results are compared with the chemical anomalies observed in Um Sohryngkew River Section in Meghalaya.
