冀东松木庄铁矿床地球化学特征及其地质意义

Geochemical characteristics of the Songmuzhuang iron deposit in Eastern Hebei Province and its geological significance

沉积变质型铁矿是冀东地区最主要的铁矿类型,松木庄铁矿床是该类型的典型代表。本次工作通过对区内矿石进行主量元素、微量元素、稀土元素测试,还原松木庄铁矿的成矿环境,同时分析其成矿物质来源。研究结果表明:此类型铁矿石的主要是成分是TFe_(2)O_(3)和SiO_(2),同时有少量的陆源碎屑岩加入,成矿物质来源于热水和海水的混合液。

Sedimentary metamorphic iron ore is the most important type of iron ore in eastern Hebei Province,and the Songmuzhuang iron deposit is a typical representative of this type.In this work,major elements,trace elements and rare earth elements are tested to restore the ore-forming environment of Songmuzhuang iron mine and analyze its mineral sources.The results show that the main components of this type of iron ore are TFe_(2)O_(3)and SiO_(2),and a small amount of terrigenous clastic rock is added,and the ore-forming material comes from the mixture of hot water and seawater.
