In order to determine fired conditions of the meteorite which occurred during the meteorite fall, Shenqiu meteorite samples were fired in an oxidizing atmosphere and a reducing atmosphere at temperatures up to 1300 °C, respectively. These samples also were fired at 800, 1000 and 1200 °C respectively for different time (up to 24 h). Mössbauer spectroscopy Fired meteorites Phase changes REFERENCES Sprenkel-Segel E L .
