滇西离子吸附型稀土矿床特征研究

The Deposit Characteristics Study of Ion-absorption Type REE in West Yunnan

临沧花岗岩主体岩性为黑云母二长花岗岩,该岩性在地势相对平缓的中山和中山丘陵地区形成巨厚的风化壳,其全风化层是主要的稀土元素主要的富集层位,矿体呈层状、似层状,目前初步评价认为,本区离子吸附型稀土矿具备形成大型矿床的潜力。

The Lincang granite are mainly composed of biotitic monzogranites, which forms a huge thick weathering crust in relatively flat terrain of the high mountain and hilly areas. The whole weathering layer is the main enrichment horizon of rare earth elements. The ore body is stratiform and stratiform-like, At present, The The Deposit of Ion-absorption Type REE have the potential to form large deposits in this area.
