| 摘 要： | 通过对龙头山金矿床不同地质体岩石稀土地球化学特征的初步研究，发现无论是稀土总量，配分曲线，还是δ（Eu）值特点都表明区内金矿体与石英斑岩、角砾岩最为相似，金矿体与石英斑岩、角砾岩在漫长的地质过程中具有继承性演化的特点，成岩成矿关系密切。因此，在今后的找矿预测与勘查中，龙头山金矿需要真正依据中低温次火山期后热液型金矿的成矿特征开展工作，除了在斑岩体内找矿外，还应注意在其他有利构造区段找矿。

| Abstract: | Through the preliminary study of the different geological body rock of rare earth geochemical characteristics in Longtoushan，it is found that no matter the total of the rare earth，the distribution patterns，or features of δ（Eu）value，which indicate，gold ore bodies in the region are the most similar to the quartz porphyry and breccia，and gold and quartz porphyry，breccia in the long geological process has inherited the characteristics of evolution with a close mineralization relationship. Therefore，during the prospecting and exploration of Longtoushan gold mine in the future，Longtoushan gold ore should carry out the work according to the mineralization characteristics of middle-low temperature secondary volcanic post thermal type gold ore. Except for ore-prospecting in porphyry，other ore prospecting at favorable tectonic section should be paid attention. |
