Abstract

The Raman spectroscopic technique has been utilized to determine the silicate composition and structure of Kamargaon meteorite (an ordinary chondrite L6 type; Kamargaon: 26°39ˊ01 ̋ N and 93° 46ˊ 02 ̋ E, India). The micro-Raman spectra in the range of 100-2000cm−1 revealed principal characteristic bands of the major minerals: olivine, pyroxene and plagioclase. Fourier transformed infrared technique is used as complementary to the Laser Raman spectroscopic method. The presence of some mineral phases such as kamacite and taenite as well as troilite and chromite were determined by X-ray diffraction method. The present study demonstrates the usefulness of Laser-Raman spectroscopic method in identifying high pressure mineral phases which are present in the shocked meteorite.
