对胶东据同位素的系统研究表明，本区据及其金矿床的成矿物质主要来自胶东岩群，燕山期是本区主要成岩成矿期，招远一莱州矿带放射成因铅由西向东有逐渐增高的趋势，这种现象的产生是受本区地层结构和岩石类型制约的。给出了在不依赖于其它同位素测试数据的情况下，利用铅同位素各参量的谐和性解析上交点年龄的方法。从而显示了本区各种同位素测定结果的和谐性、一致性。
According to the systematic study of Jiaodong isotopes, the ore-forming materials of this area and its gold deposits mainly come from the Jiaodong Group, and the Yanshanian period is the main diagenetic and mineralization period in this area. The lead causes of lead in Zhaoyuan-Laizhou ore belt are from west to east Gradually increasing trend, this phenomenon is generated by the strata structure and rock type constraints. The method of using the harmony of the parameters of Pb isotopes to analyze the upper intersection age is given without dependence on other isotope test data. Thus showing the harmony and consistency of various isotope determination results in this area.
