摘　　要：龙陵-潞西花岗岩带风化壳离子吸附型稀土矿主要赋存于花岗岩风化壳上部全风化层、中上部强风化层内,花岗岩出露面积大于1000km^(2),风化壳保存程度高,厚度大于10m,单工程平均稀土总量(ΣREE)0.05%~0.107%,成矿地质条件较好,具有较大找矿潜力。The ion adsorption type rare earth deposits in the weathering crust of the Longling-Luxi granite belt mainly occur in the upper fully weathered layer and the middle upper strongly weathered layer of the granite weathering crust.The exposed area of the granite is greater than 1000km^(2),and the degree of preservation of the weathering crust is high,with a thickness greater than 10 meters.The average total rare earth content in a single project is(ΣREE)0.05%~0.107%,with good ore-forming geological conditions and significant prospecting potential.
