In the CuddaIore sandstones of Mio-Pliocene age in the east coast of Tamil Nadu, the lignite horizon in Neyve1i is succeeded by pebbly sandstones with petrified tree trunks in Tiruvakkarai. Obviously, fluctuations in climate during Mio-Pliocene gave rise to different environments of deposition of sediments and vegetal matter, resulting in the carbonisation of vegetal matter in Neyveli and siliceous petrification of tree trunks in Tiruvakkarai.

Abstract


In the CuddaIore sandstones of Mio-Pliocene age in the east coast of Tamil Nadu, the lignite horizon in Neyve1i is succeeded by pebbly sandstones with petrified tree trunks in Tiruvakkarai. Obviously, fluctuations in climate during Mio-Pliocene gave rise to different environments of deposition of sediments and vegetal matter, resulting in the carbonisation of vegetal matter in Neyveli and siliceous petrification of tree trunks in Tiruvakkarai.
