Host rocks to the Fe-Nb-REE orebodies at Bayan Obo, Inner Mongolia, China, include dolomitic marble and K-rich slate. Microphotographic evidence demonstrates that these rocks formed by autometasomatic atic phenomena. The protolith of the dolomitic marble is magmatic carbonatite, whereas the protolith of the K-rich slate is trachytic volcaniclastic rock or volcanic tuff.
