熊耳裂谷火山岩系金-多金属矿床成矿模式

The genesis model of the gold-polymetal deposit from the volcanic rocks in the Xiong'er rift

应用热水成矿理论,首次提出豫西熊耳群裂谷火山岩系金 多金属矿床成矿矿源卤水是火山期后高温硅钾卤水,认为该区金 铅 锌 银 多金属矿床为火山期后高温硅钾卤水成因,成矿作用以硅钾卤水交代、充填及热水沉积为主,形成完整的火山热液成矿系统,主成矿时间为熊耳期。

Guided by the theory of hydrothermal metallogenesis, it is first brought forward that the metallogenetic fluid of the goldpolymetal deposits,which fell into volcanic rock series,of the Xionger rift in west Henan,is the high thermal siliconpotassium brine after the volcano period,which is deemed to form the multimetal deposits of gold,lead,and silver zinc in this area.It is also deemed that the main metallogenesis are metasomatosis of siliconpotassium brine,filling in and hydrothermal sedimentation and that the dominating matallogenetic epoch is Xionger period.
