| 摘 要： | 铝稀综合矿是由钙红土中的粘土矿物经风化阶段的淋滤脱硅的矿物转变，稀有稀土被吸附而富集，和沉积阶段水浸脱硅的矿物转变和沉积，稀有稀土氧化物被转变矿物所夹固和包裹而成，沉积场所为古陆边缘半封闭－封闭沉积盆地的斜坡地段，为进一步找矿指出了方向。

| Abstract: | The bauxite-rare-rare earth minerals are formed by the clay in the calcareous laterite conversion and rare and rare earth minerals being absorbed and agglomerated during leaching and desilication in weathering period;and minerals conversion and sedimentation and rare and rare earth oxides being covered by the converted minerals in water soaking and desilication in sedimentation period.The sedimentation area is in the declivity sections of closed/semi-closed sedimentary basin at the edge of old land,which shows the direction of ore exploitation. |
