| 摘 要： | 云南毛坪铅锌矿床是滇东北铅锌成矿带中重要的矿床之一,以毛坪铅锌矿床Ⅰ号矿体为例,在深入研究矿床地质特征的基础上,将其赋存地层———宰格组中第二段(D3zg2)NE向断裂构造岩的稀土元素配分模式划分为四类,讨论了其稀土元素地球化学特征,提出了稀土元素地球化学找矿标志,为隐伏矿预测提供了重要的地球化学信息。

| Abstract: | The Maoping lead-zinc deposit is one of the most important deposits in the Northeast Yunnan Pb-Zn mineralization field. On the basis of the geological features of the deposit, as exemplified by the No. 1 orebody of the Maoping Pb-Zn deposit, the REE patterns of NE-trending fault tectonites in the Zaige Formation have been classified as four types. The REE geochemical characteristics have been discussed. The REE geochemical indicators of ore exploration have been proposed. Some important geochemical information about the prognosis of concealed ores has been developed. |
