The article presents a study which examines the characteristics of rare earth elements (REE) in Chahe copper (Cu) deposit in Yunnan Sheng, China. Topics geological survey of the deposit which reveals morphology of ore bodies, ore minerals and gangue minerals found in the deposit, activation of REE in hydrothermal alteration at high water to rock ratios and analysis of the REE samples which shows negative anomaly of Europium, right sloping and belonging to the Light REE (LREE)-rich type.

The article focuses on a research paper discussing the geochemical characteristics of rare earth elements (REE) in quartz of Chahe copper deposit in Yuanjiang in Yunnan, China. It mentions that REE patterns of quartz in the deposit is characterized by enrichment in light REE. It also suggests that mineralization occurs in an oxidized environment and ore-forming fluids are from mixed sources.

The article discusses the research study conducted to examine the geologic history of the iron oxide copper gold (IOCG) deposits in Southwestern China that was associated with polymetallic mineralization. It reveals the age of magmatic rocks and metallogenic epoch and the coupling relationship between polymetallic elements. It also reveals the ore-forming process including the volcanic sedimentation, grenville orogenic event, and superimposed mineralization.
