The Shenqiu meteorite was investigated by Mössbauer spectroscopy at room temperature, atomic absorption, X-ray diffraction and scanning electron microscopy. 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).
