| Description | REE (rare earth elements) clays are a unique deposit type originated by lateritic weathering of predominantly feldspar rich rocks with accessory content of REE minerals. This deposit type was first described in southern China. Residual deposits represent very important source of high demand heavy REE. The parental deposit Miaoya is composed mainly of large intrusions of magmatic carbonatites andsyenites. Those rocks are enriched in REE and Nb, which are related to rare accessory minerals. Carbonatites penetrate the massif of alkaline syenite. The deposit should be actually ready for REE mining in open pit style, but the presence of REE-rich residual deposits opens up also the possibility of chemical extraction of REE insitu. This paper provides data of basic research of primary rocks and the first information about actually rediscovered clays (mineralogy, REE hosts and detailed geochemical analysis of residual crusts). |
