Geological Significance of Rare Earth Elements in Chinese Mount Huaying and their Applications

Abstract:

Analyses of REEs in 25 bulk samples collected from the Late Permian Longtan Formation in Mount Huaying district of Sichuan Province were determined useing Inductively Coupled Plasma Mass Spectrometry. The results indicate that REEs patterns are not controlled by materials from the sea, whereas the contribution of land plants is less than 0.5%. The ultimate sources of REEs are from terrigenous material as indicated by negative Eu anomaly. The Mount Emei basalt contributes to REEs enrichment of study area and all samples belong to the LREE-rich type and are enriched in LREEs relative to HREEs. So the sources of REEs are controlled by terrigenous material of Mount Emei basalt. Rare earths are an interesting group of metals that have recently become quite useful in high tech, and today they are strategic materials in the world economy. Besides, REEs play a key role in the green energy sector, REEs wide range of uses.
