Research Progress on Sources of Rare Earth Minerals from Permian in Western Guizhou

As an important strategic mineral resource of the country, rare earth plays a key role in various fields such as national defense industry, electronics industry, medical treatment, metallurgy, machinery, petroleum, chemical industry, agriculture and animal husbandry. As a country with rare earth resources, the main types of ore deposits in China are magmatic type, pegmatite type, gas-derived hydrothermal type, sedimentary rock type, placer type and weathered crust type. As a newly discovered type of deposit, Permian rare earth deposits in northwest Guizhou have attracted more and more attention in recent years. The source of rare earth materials is the basis of the study on the genetic mechanism and distribution of ore deposits, and has important research value. The source of rare earth materials in this area can be identified by petrological, geochemical and geochronological methods. Through comprehensive analysis, it is concluded that the source of rare earth materials in this area is closely related to the large igneous province of Emei Mountain, mainly including basic basalt, medium acid igneous material and pyroclastic material.
