辽宁鞍山齐大山铁矿床地球化学特征及地质意义
|
摘要
为研究辽宁齐大山铁矿床的成矿物质来源及形成环境,选取典型铁矿石进行主量元素、微量元素和稀土元素分析测试。结果显示,铁矿石主要由TFeO和SiO_2组成,其他主量元素及微量元素、稀土元素含量均较低,页岩标准化稀土元素配分曲线呈轻稀土元素相对亏损、重稀土元素相对富集型,具有一定的Eu、Y、La的正异常和弱的Ce异常,以及较高的Y/Ho值。研究表明,齐大山铁矿是由极少碎屑物质加入的化学沉积岩,其成矿物质主要来源于热水和海水的混合作用,是在海底一定缺氧的环境下形成的,矿床是与海相火山沉积有关的前寒武纪火山沉积型铁矿。
The Qidashan banded iron formation(BIF) is located in the Anshan area of Liaoning Province. In order to constrain the origin of ore-forming material and metallogenic environment, whole rock major and trace elements of typical iron ores and host rocks have been analyzed. The iron ores of this deposit are mainly composed of FeO and SiO_2. Other elements are generally low. Shale-normalized patterns of rare earth elements(REE) demonstrate that the iron ores are characterized by depletion of LREE, enrichment of HREE, apparent positive La-Eu-Y anomalies, negative Ce anomaly and high Y/Ho ratios. Such geochemical features indicate that iron ores of Qidashan were chemical sedimentary which involved with a few clastic components.The ore-forming material mainly originated from both hydrothermal fluids and seawater. The deposit is formed in a hypoxic environment on the sea floor, and is a meta-volcanic sedimentary type iron deposit related to Precambrian marine volcanism.
