The Yulong porphyry copper deposit,one of the super-large porphyry copper deposits in the world,has aroused great interest among researchers and a great amount of achievement has been made since its discovery. With the exploitation of Yulong porphyry copper deposit entering into a new phase,it is important to review and summarize the study results of Yulong porphyry copper deposit because the understanding of mineralization characteristics and model will not only give a exploration direction in the area but provide a solid base for subsequent exploration. This study,taking use of Micromine,established a 3-D model of main orebodies and then analyzed the spatial distribution rules of orebodies and ore types. Based on the analysis of whole-rock,trace elements and REE,and geochemical characteristics of fluid inclusion,metallogenic model of the Yulong porphyry copper deposit in combination with isotopic dating was established. Therefore,the establishing of the model is of great significance for guiding the exploration breakthrough and potential assessments both in the Yulong porphyry copper deposit as well as porphyry copper deposits in the Sanjiang area.
