摘要
稀土金属在国民经济建设中占有重要地位.稀土元素化学性质非常活泼,由于"镧系收缩",元素间具有极为相似的化学性质和相近的地球化学行为,在自然界常紧密共(伴)生在一起.邦歪地区处于较好的地质-地球化学成矿带上,稀土元素地球化学背景含量高,分配分布较均匀,稀土元素组合非常具规律性,找矿前景良好,成矿以轻稀土(La-Ce-Nd)为主,共(伴)生Dy、Pr、Eu、Gd、Sm等重稀土.
Rare Earth metals occupy an important position in the national economic construction.Rare Earth elements are very active in nature.Because of the lanthanide contraction,the elements have very similar chemical properties and geochemical behaviors,and are closely associated with each other in nature.Bangwai area is located in a better geological and geochemical metallogenic belt,Rare Earth elements showed high geochemical background and the distribution is uniform,element combination showed regularity and great prospecting potential,prospecting dominated by light Rare Earth elements(La-Ce-Nd),with Dy、Pr、Eu、Gd、Sm and other heavy Rare Earth elements.
