辽宁宽甸砖庙矿区硼矿床地球化学特征

GEOCHEMICAL CHARACTERISTICS OF THE DEPOSIT IN THE ZHUANMIAO AREA OF KUANDIAN, LIAONING

砖庙矿区硼矿石及含硼大理岩以富镁为特征,B的富集与Mg的富集关系密切。岩(矿) 石在蚀变(或成矿)过程中伴随着微量元素的迁移、富集,岩(矿石)的REE丰度变化范围较大。 通过对含硼白云质大理岩C、O同位素及B同位素地球化学进行分析显示了该矿床海相沉积碳酸盐 岩的特点,地层及矿体中的硼质同来源于深部。

The characteristic of szaibelyite and boracic dolomitic marble of zhuanmiao area is that it enriches in Mg. The enrichment of B and Mg has close relations. In the process of alternation or mineralization, the REE abundance changes in a large range with the movement and the enrichment of the microelement. Analyzing the Geochemistry of C. O isotopes and B istope in boracic dolomitic marble, it can be seen that the ore is marine sediment carbonate type, that is, the boron in the layer and in the ore came from the depth.
