| 英文摘要 | According to mineralogical composition carbonatite dykes at Bayan Obo REE-Fe-Nb deposit, Inner Mongolia, can be divided into three types: the dolomite type, the dolomite-calcite type and the calcite type. Based on the REE and trace element geochemistry of three types of the carbonatite dykes, they may correspond with the different evolutionary stages of the carbonatite magmatism. The dolomite and dolomite-calcite types correspond to the early stage of the carbonatite magmatism, with increasing REE contents the ratios of (La/Nd)(n), (La/Y)(n) and (La/Yb)(n) increasing. Whereas the calcite type highly enriched in total REE contents corresponds to the late hydrothermal stage of carbonatite magmatism, with increasing REE contents the ratios of (La/Nd)(n), (La/Y)(n) and (La/Yb)(n) are decreasing. This is also concordant with the major REE mineralization stage of the Bayan Obo deposit. |
