IDENTIFICATION OF MINOR MINERALS IN RIVER SEDIMENTS THROUGH FTIR STUDY – A NEW APPROACHS. MURUGESANAbstract This study demonstrates that the grain size analysis gave the detailed mineralogy through Fourier Transform Infrared Spectroscopy. The four selected sites among 39 were subjected to grain size(320, 300, 250, 210, 177, 149, 125, 105, 74, 53 and 44 mm) separation using dry sieving through ASTM mesh sieves. Those grain sizes of four sites were taken as category II whereas the sample as given is taken as category I. FTIR spectrum was taken and analyzed for all the grain sizes of four different sites and additional minor minerals identified in category II when compared to category I. The weight percentage of individual grain size for 320 mm are measured to discuss eathering, erosion and pressure due to sedimentation rate. |
