FTIR, XRD,SEM/EDAX ANALYSIS OF COASTAL SOIL SAMPLES OF KANYAKUMARI DISTRICT IN FULL MOON AND NEW MOON DAY.

Beaches are one of the important land forms and the most important feature of coastal morphology. Coastal soil samples contain the most economically important mineral accumulations. The total land mass of the earth we can live only on 30% of our planet. Our survival is threatened the non-biodegradable wastes were accumulated in the coastal region. Accumulation of non-biodegradable wastes also affects tides. Tides are one of the most important phenomena in the world they move in and out around twice a day. However, full moon and new moon day also affect the sea level and may cause both higher and lower tides. In this present study, concentrated the variation of coastal soil samples of kanyakumari district in full moon and new moon day. The qualitative identification of minerals were carried out by using FTIR and XRD techniques. The observed XRD patterns indicate quartz, feldspar, calcite, kaolinite, hematite and illite. SEM image of coastal soil sample was taken at 20kv with different magnification shows different morphology. Mineralogical studies in FTIR and XRD confirm the variation of minerals in full moon and new moon day. In FTIR study the absorption frequencies of the peak and band tentative assignments are different in full moon and new moon day. Elemental composition study i.e. EDAX clearly shown the elemental variations in full moon and new moon day. Morphological study (SEM) clearly showed the different structure in different magnification.
