摘要
寨上金矿是武警黄金部队继阳山超大型金矿之后,在西秦岭地区发现的又一特大型金矿。通过研究区域地质背景、矿床地质特征,分析主要控矿条件,总结成矿规律,研究矿床成因,建立了该矿床的成矿模式,即盆地热水沉积为成矿打下良好的基础,大气降水和岩浆热水的混合形成的成矿流体在断裂构造内迁移形成,在断裂破碎带内由于温度、压力以及氧、二氧化碳逸度的变化,成矿物质沉淀富集成矿。
Zhaishang gold deposit is another super-scale deposit in the western Qinling. Based on the research of regional geological background and characteristics, main controlling-mine condition, mineralization regularity, the author built the metallogenetic model and found that the hydrothermal sediments in the basin lay a good foundation for the mineralization. Atmospheric precipitation and magma mixed and moved to faults, where mineralization enriched due to the changes in temperature, pressure and oxygen, carbon dioxide fugacity.
