Read More2002-4-1 · Clay mineral analyses were carried out on late Maastrichtian–early Palaeocene (Cretaceous–Tertiary) sedimentary rocks in the Ariyalur area of the Cauvery Basin (southeastern India). These investigations were aimed at determining the sedimentary provenance and palaeoclimate of the area in the latest Cretaceous and earliest Tertiary.
