摘要
本文通过岩石、矿石的稀土元素数据分析,对贵州省赫章县菜园子式菱铁矿的矿床物质来源和成矿环境进行研究。稀土元素配分曲线及其相关参数表明,铁矿的成矿物质来源兼有大陆与深部来源;泥盆纪不同时代地层的Ce/Ce*值曲线反映了水城-紫云-南丹晚古生代裂陷槽的变化;各种地球化学特征证明晚古生代裂陷作用对矿床的形成有重要控制作用。
In this paper, by analysis the REE data of rock and ore, the mineral component and metallo- genie environment of Caiyinzi siderite of Hezhang are studied. REE distribution curve and relative parameters reveals that the mineral component sources are continent and seep source, the Ce/Ce ＊ value in different stra- turns of the Devonian period reveals the change of Shuicheng - Ziyun - Nandan upper Paleozoic Era aulaco- gen, each geochemical feature improves that upper PaJeozoic Era taphrogeny has important control action in the formation of deposit.
