| 摘 要： | 稀土元素在地质体中的丰度及分布形式与地质体的发生发展及物质组成有关.通过对比分析矿床的稀土元素组成特征及分布模式,研究矿床围岩、蚀变带及各类矿石的稀土元素地球化学行为,认为在高水/岩比值下热液蚀变作用使其稀土元素产生明显的带入和带出,但成岩和成矿物质具有继承性演化的特点.含金石英脉的稀土元素地球化学特征表明成矿流体具有多源性.石英脉成因不同,是不同成矿阶段热液与构造共同作用的产物.本次工作发现的硅质岩,其地球化学特征表明是一种混有火山物质或陆源物质的过渡类型热水沉积岩,可能指示该矿床早期存在热水喷流成岩成矿作用.

| Abstract: | The Abundance and distribution of rare earth elements(REE)are related to the formatin and evolution of geologic bodies in Jinshan gold deposit.By analyzing and comparing the REE characteristics of wall rock,altered rock zone and ores from the deposit,it is concluded that the REE migrated and enriched during the rock fluid interaction,with inheritance of some constituents from original rocks at the same time.The geochemical characteristics of REE in the auriferous quartz veins indicate that the ore forming fluids are multi source in nature.The quartz veins are formed by the cooperation of hydrothermal alterations and structural movements at different ore forming stages.The siliceous rock in the orefield,which was firstly found by the study,is geochemically a kind of hydrothermal sedimentary rock mixed with volcanic and /or terrigenous materials,suggesting a hydrothermal exhalative mineralization in the deposit. |
