摘要：
Here, we present comprehensive electron probe micro analysis, laser Raman spectroscopic and X-ray diffraction (XRD) studies on the Mahadevpur H4/5 chondrite. The calculated full width at half maximum (FWHM) value of similar to 14-17 cm(-1) for the Raman peaks in the Mahadevpur meteorite is in accordance with the shock stage of S4 with medium shock pressure regime of 30-35 GPa. The nanodiamonds were characterized with the observation of Raman peaks at 1333-1358 cm(-1) and 1600 cm(-1). The FWHM value of the Raman peaks reflects shock metamorphism in the meteorite. The XRD technique provides further independent validation of the nanodiamonds.
