Typomorphic Characteristics and Geological Significance of the Pyrites from Katbasu Gold Deposit,Xinjiang
Katebasu large gold deposit was found in the middle of Tianshan mountain,Xinjiang in recent years.It is an important industrial base of gold mining and metallurgy industry in the construction of Xinjiang green mining industry chain.Pyrites in deposit develop extensively and they are related to mineralized minerals.The paper mainly study miner-al feature and their implications of pyrite by geological record,microscopic identification,photometer,sclerometer and electron microprobe analysis.The result show that the gold-bearing of granular pyrite and collective pyrite is better than others,and low reflectivity have a certain positive correlation with gold content.The hardness of pyrite in hydrothermal mineralization period has little correlation with gold content.The results of pyrite pyroelectricity show distribution of the type P pyrites reduced gradually and the type N pyrites increased gradually with the loss of the height.The temperature of pyrite is mainly concentrated in 170 ℃～360 ℃,and the environment changes from high-medium temperature.
