摘要
风化壳淋积型稀土矿床，在湘南地区普遍发育。具有分布面广、厚度大、品位较富、浸取率高的特点。在风化壳分层中，矿体呈似层状、透镜状赋存于上部、中部，顶部及下部无矿。矿化原岩（花岗岩）含稀土总量０．０６％以上才具找矿价值。
The weathering crust-eluvial type REE deposits develop widely in southern Hunan. They are characterized by extensive distribution,big thickness,higher contents and better leaching rate. Layer-like or lenticular ore bodies occur in the upper part of the weathering crust,but in top, middle and lower parts of it there are no ore bodies.Only when the content of REE in origional rocks(granits)reaches to more than 0.06%,will these granites be valuable for REE ore searching.
