| 摘 要： | The lead isotopic compositions of feldspars and ores from granitoid rocks andassociated hydrothermal ore deposits in eastern China are strictly controlled by the nature and age of basement rocks in different tectonic belts.In eastern China,at least five discrete plumbotectonic provinces can be distinguished:the North China platform province,the Qinling province,the Lower Yangtze prov-ince,the Nanling province and the Southeast China coastal province.Each province is marked for unique types of mineralization and ore-metal assemblages.

| Abstract: | The lead isotopic compositions of feldspars and ores from granitoid rocks and associated hydrothermal ore deposits in eastern
China are strictly controlled by the nature and age of basement rocks in different tectonic belts. In eastern China, at least
five discrete plumbotectonic provinces can be distinguished: the North China platform province, the Qinling province, the
Lower Yangtze province, the Nanling province and the Southeast China coastal province. Each province is marked for unique
types of mineralization and ore-metal assemblages. |
