摘要
为了研究近地表地下水与菱铁矿作用后水中稀土元素的地球化学特征,开展了室温下地下水与菱铁矿长期(100天)作用的模拟实验。实验结果显示,菱铁矿中的稀土元素(REE)在水中的溶解度低于常见的沉积岩矿物,反应后的样品在稀土的w(溶液)/w(岩石)曲线的Y处出现明显的波谷,可作为地下水与菱铁矿反应的明确判别标志。
In order to study the rare earth elements(REEs)variation during near-surface groundwater-siderite reaction,a long-term simulation experiment(100days)was carried on.The result showed that the solubility of REEs in siderite was lower than other common sedimentary minerals,and the REEs in reaction samples showed Y depletion in w(solution)/w(rock)curve.Both of the key points can be a clear discrimination of groundwater and siderite reaction.
