对比研究了枣子沟金矿区内不同类型矿石与成矿有关的岩浆岩及地层的稀土元素地球化学特征，借以示踪成矿物质来源。研究表明，矿床不同类型矿石的稀土元素配分曲线既有相似又有差别，反映成矿物质具有多样性；矿石与容矿岩石（地层、岩浆岩）稀土元素配分曲线颇为相似，总体呈右倾型，具Eu负异常。表明成矿与容矿岩石（地层、岩浆岩）具有一定的成因联系。成矿物质来源于壳源及壳幔混合。地幔流体可能参与了矿床成矿作用。成矿环境表现为早期还原，晚期由还原向氧化转化。

Comparative study on different kinds of ores , metallogenic magmatic rocks and geological features of REE in strata of Zaozigou gold deposit was conducted to trace the source of ore-forming minerals .Research shows that REE curves of different ores in the deposit are similar while distinct meaning complex ore -forming minerals .Ores and host rocks ( strata and magmatic rocks ) curves take on similar forms ,generally the rightwards type and Eu negative a-nomaly .This indicates metallogenesis and host rocks are related .The ore-forming minerals came from crust source and mixture of crust and mantle .Mantle fluids may have participated in the mineralization .The early ore-forming settings are reduction and later transmitted from reduction to oxidation .
