摘要
This paper studies the mineralization characteristics, ore texture, the structure and the main gold-hosting mineral pyrite in the Erdaogou gold deposit of western Liaoning. And it further discusses the mineralization temperature, epoch and direction of hydrothermal activities The results show that the deposit has experienced hydrothermal and hypergene stages. The hydrothermal stage can be subdivided into quartz-pyrite, quartz-polymetallic sulfide and quartz- carbonate three phases. There may be several episodes of hydrothermal activities, and the former was superposed by the latter. The metallogenic hydrothermal solution had high temperature in the early time, while the metallic mineral mainly precipitated at lower temperature. The gold in the No.Ⅲ and No.Ⅴ ore vines occurs horizontally and vertically with inhomogeneous distribution, and the gold grade tends to be higher towards the southeast from the top to the bottom. This may indicate that the metallogenic hydrothermal solution possibly came from the southeast. The detailed research in this work on rules of gold enrichment of veins No. Ⅲ and No.Ⅴ has guidance significance for the production of the mine as well as resource exploration.
