Rare earth elements in standard samples of ocean Fe-Mn nodules and crusts

Contents of rare earth elements (REE) in standard samples of Fe-Mn nodules (SDO-5, 6), Fe-Mn crust (SDO-7), and red clay (SDO-9) have been determined by ICP-MS and instrumental...铁锰结核（Fe-Mn nodules）标准样品（SDO-5、6）、铁锰结壳（Fe-Mn crust）标准样品（SDO-7）以及红黏土（red clay）标准样品（SDO-9）中的稀土元素（rare earth elements, REE）含量，已采用电感耦合等离子体质谱法（ICP-MS）及仪器分析手段完成测定。
