摘要
上庄金矿位于焦家断裂带北段,赋矿围岩中发育黄铁绢英岩化、钾化、碳酸盐化和粘土化蚀变。通过岩石化学分析显示,钾化、黄铁绢英岩化及粘土化蚀变岩之间有明显的物质交换。上庄金矿成矿作用和水岩反应可以概括为动态成矿与相应的水岩反应机制,热液对流过程中物理化学条件的动态变化是制约水岩反应和成矿物质活化-迁移-聚集的关键,水的电离反应是蚀变矿化过程的重要环节之一。
Shangzhuang gold deposit locates in the north section of Jiaojia fault zone.Beresitization,potassic alteration,carbonatation and argillic alteration develops in the ore-bearing wall rocks.The lithochemistry a-nalysis shows that obvious interchange of material takes place between rocks of potassic alteration,beresiti-zation and argillic alteration.The mineralization and water rock interaction of Shangzhuang gold deposit can be summarized as a dynamic mineralization and related water rock interaction mechanism.The dynamic change of physical and chemical conditions of hydrothermal convection is the key of controlling the water rock interactions and the activation-migration-accumulation process of ore-forming materials.Ionization reac-tion of water is one of the most important parts in the alteration and mineralization process.
