| Abstract: | The geological map showing distribution of carbonatite dykes around the Bayan Obo Nb-REE-Fe mine was firstly presented.A systematic study on occurrence,mineralogical type,rock texture,mineral component and REE content of those carbonatite dykes has been carried out.The results indicate that there existed differences of magmatic evolution during the formation of those carbonatite dykes.It implicates that the carbonatite magma may be a source for Nb-REE-Fe mineralization of the Bayan Obo deposit. |
