A STUDY ON WEATHERING CRUST ION ADSORPTION TYPE REE DEPOSITS, SOUTH CHINA

This study deals extensively with metallogenetic conditions and genetic classification and geological characteristics of weathering crust ion adsorption rare earth elements deposits. This type of REE deposits is suffered endogenetic and epigenetic metallization. They are divided genetically into 3 types based on meallogenetic characteristics:(1)granite-weathering crust type;(2)migmatite-weathering crust type(3)volcanic-subvolcanic weathering crust type. Deposits show some regularities on REE minoralizalization. There are five types of REE distribution clearly correlated. There is a splendid prospecting area in south China.
