| 摘 要： | 采取了皖北任楼煤矿太原组灰岩和灰岩水样品进行稀土元素测试分析,结果显示灰岩样品稀土总量较低,平均为36.947×10-6,灰岩样品稀土配分模式表现为轻稀土富集、重稀土亏损型;灰岩水样品稀土总量平均为0.052 6×10-6,灰岩水样品轻、重稀土均富集,轻、重稀土之间分异明显。对灰岩含水层水岩相互作用进行研究,结果表明:轻稀土表现稳定,重稀土分异明显,尤其在Y处有一个明显的峰值;Y元素与Ca元素呈正相关关系,相比石灰岩,灰岩水的Y/Ho、Y/Dy分异更为明显。研究认为,灰岩水中Y元素的峰值效应也可作为灰岩水源识别的依据。

| Abstract: | Rare earth element analysis had been carried out for the Taiyuan limestone and limestone water collected from the Renlou coal mine,and the results show that the total rare earth element(REE) contents of limestone are low and are 36.947×10-6 in average.The rare earth element patterns indicate that the LREE is rich and the HREE is depleted;the REE contents of limestone water are 0.0526×10-6 in average;the LREE and HREE both are rich;the fractionation between LREE and HREE is clear.The water-rock interactions in limestone aquifer had been studied,and the results indicate that the LREE content is stable,the fractionation of HREE is clear,and especially that of Y is a peak,the relationship between Y and Ca is positive correlation,the fractionation of Y/Ho,Y/Dy in limestone water is more obvious than in limestone.This paper considers that the peak effect of Y can be the distinguishing basis for limestone water. |
