REGIONAL METALLOGENIC REGULARITIES OF THE ION ADSORPTION TYPE OF RARE-EARTH DEPOSITS IN GUANGDONG PROVINCE

Guangdong is one of the important mineral sites for rare-earth resources in China. The ion adsorption type is the most characteristic of the rare-earth deposits in the province. The ore-bearing protolith is broadly distributed, with favorable metallogenic conditions. Based on the research of the metallogenic features, this paper preliminarily summarizes the oreforming regularities of the ion adsorption type of rare-earth deposits from the aspects of ore-controlling conditions, distribution and enrichment of orebodies to establish the regional metallogenic model.
