Metallogenic Characteristics and Mineralization Model of the Dapingzhang Copper Polymetallic Deposits in Pu'er,Yunnan Province

The Dapingzhang copper poly-metallic deposit is a volcanic exhalation-sedimentary deposit,which hosts two types of ore bodies. Of them,one is massive sulfide ore(V1),and the other is veinlet-disseminated ore(V2). The deposit exhibits a similar mineralization space structure with the VHMS type deposit,i. e.,the upper part of the ore body is characterized bylayering and blackand the down part isveinlet and yellow. Based on the analysis on regional geological background,metallogenic characteristics and combined with evolution characteristics of the ore district,we established a metallogenic model for the Dapingzhang copper polymetallic deposit. It has significant implications for analyzing the proto Tethys of copper poly-metallic mineralization and its type,promoting the research of the Sanjiang metallogenic belt,and thus shedding light on the dominant metallogenic types of the Simao basin's early Paleozoic basement and prospecting potential and prospecting ideas.
