| Abstract: | Abstract Infrared spectra of Neyveli Lignite samples at different depths from mine cut-I and II were recorded in the region 4000–200 cm?1. Probable assignments of the bands were made with respect to the components present in the samples. The Lignite samples collected at 80m, 82m, 87m and 90m from minecut-I and 52m, 56m and 58m from minecut - II shows distinctly a band at 1500cm?1 indicating that these belong to pleistocene—miocene period, while the absence of this band in the samples at deeper depths 92m and 94m from minecut-I and 62m and 65 m from minecut-II indicate that these belong to Oligocene to Palaeocene period. |
