Siderite specimens collected from Jianshi County, Hubei, Province and Leshan County, Sichuan Province, have been studied by X-ray, diffraction analysis, wet chemical analysis, electron probe analysis and microscopic examination, and the following minerals were recognized: Kamacite, taenite, plessite and a few silicate minerals. Besides, Jianshi siderite also contains troilite, cohenite, magnetite and limonite.According to the Widmanstatten structure, the width of kamasite band (0.5-0.76mm for Jianshi siderite, 0.1-0.5mm for Leshan siderite) and content of nickel (Jianshi siderite-7.8%, Leshan siderite-8.64%), Jianshi specimen is considered to be a medium-grained octahedron siderite and Leshan specimen a fine-grained octahedron siderite.
