| Abstract: | Hyalophane Series, (K, Ba)Al(Al, Si) Si2O8, which varies in Celsian (Cn), from 5.5 to 13.8mol percent has been found abundantly in the caprock of the niobium-rare earth-iron deposits at Bayan OBO, Inner Mongolia, China. Micro-structure shows rings and bands of Cn suggesting Ba replacement as a important ore-forming process in the deposit. |
