摘要
///Petrological and petrochemical characteristics of samples from four Neo-Archean banded iron ore deposits of Baiyuli, Baizhiyan and Ekou in Wutai Mountains area and Qian’an in eastern Hebei Province are reported in this paper. The authors have found that these iron deposits have highly consistent characteristics in the following four aspects: all of the samples are depleted in Th, U, La, Ce, P and Sm and enriched in K, Nb, Sr, Hf, Er and Ti. All of the iron deposits in the four areas are depleted in light rare earth elements and enriched in heavy rare earth elements. They have obvious positive anomalies of Y and Eu, suggesting characteristics of sea water and high temperature seafloor hydrothermal solution.
