攀西地区现已发现有花岗岩型、火山岩型、混合岩型和砂岩型等多种类型的铀矿化,是康滇地轴上少有的铀矿化集中产区之一,也是康滇地轴中段铀矿找矿最有希望取得突破的地区(陈友良,2004;郭宁等,2012)。多年来的地质勘查和研究表明,区内混合岩型和花岗岩型铀矿的矿化规模相对较大,具有一定的找矿前景(陈友良,1995;姚建等,2011)。产于四川米易海塔地区的铀矿即属于较为典型的混合岩型铀矿,本文拟对其稀土元素特征进行研究,以期对本区该类型铀矿的成矿机理进行初步探
The Panxi area has been found to have many types of uranium mineralization such as granite, volcanic, mixed rock and sandstone. It is one of the rare uranium mineralization concentrated areas on the axis of Kangdian, Uranium ore prospecting the most promising breakthrough areas (Chen Youliang, 2004; Guo Ning, etc., 2012). Geological exploration and research over the years have shown that the mineralization scale of the mixed rock type and granitic uranium deposits in the area is relatively large with certain prospects for prospecting (Chen Youliang, 1995; Yao et al., 2011). The uranium ore produced in Miyihaita area of Sichuan Province belongs to the more typical mixed type uranium deposit. This paper intends to study the characteristics of its rare earth elements in order to preliminary study the metallogenic mechanism of this uranium deposit in this area
