Infrared Spectroscopical Analysis of Some Metamorphic rocks.

Abstract

The investigator is interested to study the special reference to Erode, Salem, Krishnagiri, Trichy, Madurai and Virudhunagar district of Tamilnadu, India. importance of Rocks and minerals and their study by infrared method. The rocks are grouped into three large Many workers have carried out investigation classes namely igneous rocks, sedimentary rocks, on quantitative estimation of minerals. metamorphic rocks. The mineral characters of is one of the foremost capable explanatory strategies which offer the plausibility of chemical distinguishing proof and is a powerful tool in identifying quantitative and qualitative analysis of the minerals present in geological samples. The collected samples from Tamilnadu, India are analyzed by infrared spectroscopic method and indicates the presence of quartz, feldspar, diapside, garnet and chlorite minerals. The obtained results are interpreted in light of available literature with special reference to crystallinity index, absorbance and extinction coefficient.
