在分析寒山金矿区原生矿物和氧化矿物组合的基础上,通过对黄钾铁钒的热力学计算分析得出:在常温条件下,黄铁矿要形成黄钾铁钒,所需的氧逸度较低,但需要有一个较高的碱性、富钾、富Fe2+以及富水的环境,这一条件暗示了围岩为富铁的基性火山岩在湿润的气候条件下有利于形成黄钾铁钒,同时也表明寒山金矿区氧化带的形成过程中,其气侯环境不是现在的沙漠干旱气候,而是湿润动植物繁盛的大陆性气候。结合区域地质特征,可以得出寒山金矿的氧化带可能形成于早侏罗世-中侏罗世。
Based on the analysis of the combination of primary minerals and oxidized minerals in Hanshan Gold Mine, the thermodynamic calculation and analysis of the potassium, ferrovanadium and vanadium show that the oxygen fugacity needed by the pyrite should be formed at room temperature, Lower, but requires a higher alkaline, potassium-rich, Fe2 + -rich and water-rich environment that implies that the surrounding rocks are iron-rich basic volcanic rocks that favor the formation of jarosite in humid climates Vanadium, but also shows that the formation of oxidation zone in Hanshan Gold Mine is not the present climate of desert climate, but the humid climate of animals and plants. Combined with regional geological features, it can be concluded that the oxidation zone of the Hanshan gold deposit may have formed during the Early Jurassic-Middle Jurassic.
