In sedimentary iron formations, siderite is the most abundant. In some cases, there are all grounds to sug-gest that siderite is the primary mineral whose deposition predetermined the subsequent course of iron ore deposi-tion. Without reconstruction of siderite deposition, our knowledge on iron ore genesis remains incomplete.

The results in Tables 1 and 2 indicate that the TFe of siderite ore was only 22.99%, and the iron minerals mainly exist in the form of siderite. The contents of P and S were 0.04% and 0.45%, respectively. The low content of MgO (1.90%) and Mn (0.61%) implied that only a small amount of Fe in the siderite lattice was substituted by Mg and Mn.
