Abstract |
|
|
| This study used infrared spectroscopy to determine the mineral content of soils. The soil samples were collected from the top layer of the soil at a depth of 5 cm from 63 locations in Tiruvannamalai District, Tamilnadu, using a grid technique. The top layer was so chosen in order to assess the anthropogenic influence on the nature of the soil. Charnockite, Granite gneiss, Epidote Hornblende gneiss, Amphibolite, Pyroxenite, Dunite, migmatites, Banded Magnetite Quartz, Shale, and clay are among the rocks found in the district. In the infrared spectrum, the results show that soils are composed of different minerals, such as quartz, kaolinite and montmorillonite, aragonite, hematite, feldspar and calcite. For quartz, the crystallinity index was calculated in order to determine its crystalline nature; there is disordered crystalline quartz present in the soils. According to the findings of this study, kaolinite and quartz minerals were the most abundant minerals, while montmorillonite and illite were found in moderate amounts, and organic carbon was identified in trace amounts. The FT-IR study revealed that quartz, calcite, and kaolinite were the most prevalent minerals in the soils. From the XRD analysis, confirmation of the mineral compositions of soil samples was obtained. The results of the mineral analysis using the FT-IR method are in agreement with the findings of the XRD studies. The proposed FTIR technique was shown to be useful in determining soil mineralogy because it is quick and easy to use. |
