| 中文摘要: |
| 卓潘岩体是金沙江—哀牢山富碱斑岩带中的重要岩体,位于兰坪走滑拉分盆地西部。稀土元素特征显示,卓潘岩体是一个稀土总量高,轻稀土富集,重稀土亏损的新生代岩体,岩体轻稀土元素对轻稀土总量的贡献力度由大到小为:Ce→La→Nd→Pr→Sm→Eu；与华南风化壳型稀土矿特征对比研究发现,卓潘岩体与华南风化壳型稀土矿成矿特征相似,具一定的风化壳型稀土矿的找矿潜力。 |
| 英文摘要: |
| The Zhuopan alkaline rockmass complex, which is located in the western part of the strike-slip extensional basin of Lanping, is key magmatic intrusion in the Jinshajiang-Ailaoshan alkali-rich porphyry mineralization zone. The alkaline complex is characterized with high concentration of ∑REE, LREE-rich and HREE-poor. The contribution of each light REE element to the total LREE is Ce, La, Nd, Pr, Sm and Eu according to the weighting ratio from the high to low percentage respectively. Compared with the weathered type REE deposit distributed in the Southern China, the Zhuopan alkaline complex has similar REE mineralization characteristics, therefore, there is great potential for prospecting the weathered type REE deposit within the Zhuopan alkaline rockmass complex. |
