The volcanic rocks and ores characterized by high concentrations of radiogenic lead indicate that the deposit formed on mature island-arc environment, and most of the ore lead was derived from the same environment as the associated volcanic rocks.

火山岩、矿石以富放射性成因铅为特征，反映成矿环境为成熟的岛弧环境，矿石铅与火山岩铅应属于同一来源。

SHRIMP analyses give 206Pb/238U ages ranging from 335～424 Ma for the zircons, showing a certain degree of radiogenic lead loss; so the age of 424±5 Ma reflects the minimum age of the metamorphic zircons.

SHRIMP分析表明，锆石206Pb/238U 年龄为335～424 Ma，有放射性成因铅丢失现象，因此可以推断424±5 Ma代表高压变质事件的最小年龄。
