Pollen grains of Ctenolophonidites from the Neyveli lignites of South India

Abstract

Two species of Ctenolophonidites, C. costatus van Hoeken-Klinkenberg (1966) and C. neyveliensis sp. nov., have been described from the Neyveli lignites of South India. The latter is distinct from all the earlier described species.

Neyveli lignites and associated sediments-their palynology, palaeoecology, correlation and age

“…The geology and ground water aspects of the Neyveli Formation have been studied by Krishnan (1949), Balasunder (1968), Subramanyam (1969), Gowrisankaran et aL (1987), etc. The lignite and underlying clay bands are rich in palynofossils and a number of papers have been published on their study (Navale, 1962;Thiergart & Frantz, 1963;Ramanujam, 1963Ramanujam, , 1966aRamanujam, , b, 1967Ramanujam & Ramachar, 1963Deb, 1972;Deb et al, 1973;Venkatachala, 1973;Navale & Misra, 1979;Ambwani et al, 1981;Bande & Ambwani, 1982;Reddy et al, 1982Reddy et al, , 1984Ambwani, 1983;Ramanujam & Reddy, 1984;Sarma et al, 1984;Saxena, 1984;Ramanujam et al, 1984Ramanujam et al, , 1985Siddhanta, 1986;Singh & Misra, 1991a, b, c). However, most of the above studies are largely confined to the description of palynofloras and their interpretation for inferring palaeoclimate and environment of deposition with no or little stratigraphic conSideration, particularly regarding age and correlation of the lignite deposits.…”
