淮南潘三煤矿太原组水岩水稀土元素特征
Inner Mongolia Coal Economy（2015）
Abstract
潘三煤矿1煤层底板太原组灰岩水是煤矿开采过程中影响较严重的含水层,通过对该层水样的采取,结合各种测试方法,研究了太灰水中稀土元素地球化学特征等.结果表明:太灰水中轻稀土元素范围为0.02 μg/L-0.08μg/L,均值为0.04μg/L,重稀土元素范围为0.01 μg/L-0.02 μg/L,均值为0.01 μg/L,稀土元素总量(∑REE)变化较大,介于0.03 μg/L-0.11 μg/L之间,均值为0.05 μg/L;太灰水中稀土元素分布以轻稀土亏损、重稀土富集为特征,且有明显的Eu正异常和Ce负异常.
