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 research related to formation of diabase dykes and its relation with Sanqisan uranium deposits in South China. Topics discussed include relation of diabase dykes with metallogeny of uranium depots, formation of dolerite from altered minerals including kaolinite, serpentine and chlorite, conduction of uranium lead dating analysis by multiple collector - inductively coupled plasma - mass spectrometer and diabase dykes as the ore forming material source.

The article focuses on a geochemical study related to characteristics of calcite and its significance in formation of Sanqisan uranium deposits in South China. Topics discussed include Sanqisan deposits are carbonate siliceous- pelitic rock type uranium deposit, association of uranium with chromium and zirconium which is a high field strength elements reflects as ore forming fluids of calcite, and water rock reaction of fluid and wall rock as the main mechanism of calcite precipitation.
