摘　　要：用X射线衍射(XRD)、X射线荧光(XRF)等手段对湖北鄂州博物馆馆藏当地出土的数枚锈蚀明显的清代黄铜钱币进行了检测分析.结果表明,腐蚀产物中有绿铜锌矿(Zn3Cu2(OH)6(CO3)2),还有红锌矿(ZnO)、铜盐(CuCl)、黑铜矿(CuO)等,结合当地土壤理化性质及相关文献讨论了这些产物及"蛀虫式"腐蚀形成的原因.XRD and XRF were used to identify the corrosion products on several brass coins of Qing dynasty collected in the Ezhou museum,excavated from Ezhou of Hubei province.Zn3Cu2（OH）6（CO3）2 was found in the corrosion products for the first time,besides CuO、ZnO、Fe2O3 and CuCl were also found.Futhermore,the relevant mechanism of the observed＂wormhole like corrosion＂ on the coins was discussed in terms of the physical and chemical characters of the local soil.
