Study of naturally occurring Precambrian native iron through high-pressure M\"{o}ssbauer Spectroscopy up to 10 GPa

We report here the M\"{o}ssbauer spectroscopic studies on native iron sample obtained from Proterozoic Mica Schist of Chaibasa SinghBhum craton of Eastern India at ambient condition as well as under high pressure up to 10 GPa using Diamond Anvil Cell and 4:1 methanol -- ethanol mixture as hydrostatic pressure medium. The results were compared with the studies on metallic iron under high pressure [1,2] . A slight variation in isomer shift up to 5.6 GPa and onset of a new peak corresponding to BCC$\to $HCP transformation at 9.1 GPa might indicate the magnitude of impact experienced by the sample before attaining the thermodynamical equilibrium.
