摘　　要：矿床由Ⅰ、Ⅱ两相连矿体组成，Ⅰ矿体发育在大理岩中，垂直分带明显，其地质地球化学特征与月山闪长岩体一致，是夕卡岩浆上侵贯入充填成矿；Ⅱ号矿体地球化学特征与围岩（Ｔ＿２ｂ）一致，是接触热变质作用和外生水循环淋滤成矿作用形成，成矿物质来源于地层。The deposit is composed of Ⅰand Ⅱore bodies adjacent each other.Ⅰore body developed in marble and has obvious verticalzoning,its geological and geochemical features are identical to those of yueshan diorite body.Ⅰore body was formed throughskarn magma intrusion upwards and filling.The geochemical features of Ⅱore body are identical to those of country rock(T_2 b).Ⅱore body was formed by contact thermal metamorphism and exogenetic water circulation leaching. Ore-forming materials origi-nated in strata.
