摘　　要：通过矿床地球化学特征和同位素年代学的研究，结合区域成矿规律分析，该矿床成矿物质主要来源于千里山花岗岩，成矿时代为燕山早期，成矿温度１６８℃～２４４℃，它属于岩浆期后中低温热液矿床。与柿竹园钨多金属矿、红旗岭锡（铅锌）矿、南风坳银（铅锌）矿共同组成一个完整的与千里山燕山早期花岗岩有关的矿床成矿系列。Based on the study of geochemical characteristics and isotope chronology,and combination with an analysis of regional metallogenic regulation,it is suggested that: (1)The metallogenic elements derive mainly from Qianlishan granite body. (2)The mineralization takes place in the early yanshanian,with the metallogenic temperature of 168244,which shows that the deposit belongs to the postmagmatic mesoepithermal ones. (3)Together with shizhuyuan tungstenpolymetallic deposit,Hongqiling Tin (PbZn) deposit and Nanfengao silver (PbZn) deposit,Zongshuban PbZn deposit constitute a complete metallogenic series being related with early yanshanian Qianlishan granite genetically.
