Mineral chemistry of Mahadevpur H4/5 chondrite: characterization of nanodiamonds through micro-Raman spectroscopic studies

This paper presents for the first time comprehensive spectroscopic studies on the Mahadevpur H4/5 chondrite using Electron Probe Micro Analysis (EPMA) and laser micro-Raman spectroscopic techniques. The micro-petrography reveals a coarse to medium crystalline chondritic texture with various morphological  features dispersed in a relatively medium to fine crystalline matrix, which appeared in the cover page of the journal. We found that Mahadevpur meteorite has experienced the shock stage of S4 corresponds to  30–35 GPa.  This is independently validated by   XRD technique and observation of nanodiamonds.
