Analysis on Mineral and Fluid Inclusion Composition of Jinjiazhuang Gold Deposit in the North of Hebei Province
Jinjiazhuang Gold Deposit is related with ultrabasic rocks and rare in China, in order to investigate its geochemical characteristics and genetic mechanism, this paper has analyzed the metallic mineral composition and fluid inclusion composition in the Jinjiazhuang Gold Deposit.This study has shown that the metallic minerals in the Jinjiazhuang Gold Deposit generally contains Pt, Pd, Ni and other deep-source elements, and the emergence of millerite; the content of rare earth element in major metallic minerals is generally low, the middle rare earth element is slightly rich, and Eu is usually not significant; the fluid inclusion composition contains generally a large amount of CO2, and the anionic components in ore solution is characterized by SO42>Cl>F-, i.e.sulfur-rich H2O-CO2 type; the changes in the fluid inclusion composition has certain correlations with gold content, and the changes in the salinity of the ore-forming solution also has certain correlations with ore grade.
