Abstract: As coal-uranium-rare earth joint exploration and utilization is becoming more and more significant,the authors study Mulga Rock deposits in Western Australia:Ambassador,Shogun and Emperor deposits,as a typical symbiosis case.The authors analyze the mineralization relationship among coal and uranium and rare earth in the Mulga Rock deposits from the time-space framework in details.Based upon this,this paper explores the symbiosis mineralization modes of coal-uranium-rare earth from sampling data,materials source,and material transportation perspective.Then the authors finally use the mineral systems approach(MSA)for the comprehensive genesis and economics analysis of coal-uranium-rare earth.MSA has agreat guide value for analyzing in this paper,since it focuses on the genesis relationship thus with a broad application area.The authors draw a conclusion that coal,uranium,rare earth,and other minerals should be comprehensive development and utilization,which notonly improves economic efficiency,but also can better the environment and other social governance.
