摘　　要：作为主要铜源的斑岩型铜矿床一直是研究、生产部门关注的热点。依据多年研究成果和大量文献资料，并以德兴斑岩铜矿研究新成果为实例，综述了斑岩铜矿矿质迁移沉淀机制研究的新进展，包括铜的迁移形式和演化，流体演化对铜络合物作用，铜在熔体相、流体相和晶体相配分以及铜居留场所和形式等。Porphyry Copper deposit is still a key subject for geological research because of its importance for copper source.Based on many years' research work and recent literature,this paper reviews and discusses some new progress of copper migration and precipitation mechanism during prophyry oreforming process,including copper migration forms,fluid function for copper enrichment,copper partition among melt,fluid and crystral phases and copper sink condition etc..Finally,as an example,we review some new research work on Dexing porphyry copper deposits,Jiangxi Provience.
