| 摘 要： | 个旧锡多金属矿床明显受断裂的控制。断裂(裂隙)的构造岩分析结果表明，构造岩稀土元素的特征与矿石一致，且它们有相同的来源，而与围岩具有明显的差别。矿区强烈的花岗岩岩浆汽热活动造成构造岩的稀土明显富集。根据稀土元素的分布异常圈定了隐伏矿床(体)找矿靶区，经钻孔验证已见成效。

THE REE FEATURES OF TECTONIC ROCKS AND ITS APPLICATION IN FINDING CONCEALED ORES IN THE GEJIU TIN DEPOSIT |
| |
| Abstract: | Gejiu tin deposit is obviously controlled by faults. The analyses results show that tectonic rocks has the same REE features and sources as ores, but not the same as wallrocks. It was the moving of hydrothermal of granite magma that caused enrichment of REE in tectonic rocks. According to anomalies of REE, some targets were enclosed, and one of targets has been found concealed ores by exploring. |

| Keywords: | features of REE tectonic rocks concealed deposit |
