摘　　要：通过对粤东地区地层和岩石中成矿元素含量和区域地质背景的分析,认为粤东地区铜铅-锌-银成矿作用与燕山期的构造-岩浆作用关系密切,成矿物质中银-铜-锌以下地壳来源为主,铅则以上地壳及沉积地层来源为主。After analyzing ore-forming elements content and regional background in strata and rocks of Eastern Guangdong, it has believed that Cu, Pb, Zn, Ag metallogenic process is closely related to tectonic-magma movements, and the Ag, Cu, Zn mainly originated from lower crust, while most Pb came from upper crust and sedimentary strata.
