WebOct 1, 2016 · We investigated the distribution of crystalline iron oxides (Fec), amorphous iron oxides (Feo), δ 13 C and Fe-bound OC in soil aggregate fractions of red earth (Ferrisol). The results showed that the δ 13 C values in microaggregate and silt+clay fractions were significantly lower than macro- and mesoaggregate ( p < 0.05).

At least four allotropes of iron (differing atom arrangements in the solid) are known, conventionally denoted α, γ, δ, and ε. The first three forms are observed at ordinary pressures. As molten iron cools past its freezing point of 1538 °C, it crystallizes into its δ allotrope, which has a body-centered cubic (bcc) crystal structure. As it cools further to 1394 °C, it changes to its γ-iron allotrope, a face-centered cubic (f… WebA typical piece of iron or copper (Cu) is polycrystalline.
