| 摘 要： | 依据河北省区域岩石地球化学调查成果,讨论了区内不同成因类型含铁岩系的地球化学特征。其中重要的沉积变质铁矿地层中Al2O3、Ti、P、V、Cr、Ni、Cu、Zn的质量分数和w(Fe2O3)/w(FeO)、w(Sr)/w(Ba)、w(La)/w(Y)较高,Rb、Li、Cs、Sc的质量分数及w(K2O)/w(Na2O)较低;海相沉积型铁矿地层中强烈富集Sb、Li、B、Hg、Sr和K2O,同时贫化FeO、Na2O、CaO、Mn、Rb等元素;主要接触交代型铁矿围岩中CaO、MgO的质量分数较高,SiO2、Al2O3、K2O、Mn、Ti、P、V、Cr、Zr、Ba、REE的质量分数及w(Fe2O3)/w(FeO)较低。这些地球化学特征反映其特定的地质构造环境。

| Abstract: | This paper has discussed geochemical characteristics of different genetic types of ferruginous strata on the basis of achievements made in regional geochemical rock survey.In strata of important sedimentary iron deposits,the quality fractions of Al_2O_3,Ti,P,V,Cr,Ni,Cu,Zn and the w(Fe_2O_3)/w(FeO),w(Sr)/w(Ba) and w(La)/w(Y)ratios are relatively high,whereas the quality fractions of Rb,L,Cs,Sc and w(K_2O)/w(Na_2O)ratios are relatively low.The strata of marine sedimentary iron deposits are strongly enriched in Sb,Li,B,Hg,Sr and K_2O,but depleted in FeO,Na_2O,CaO,Mn,Ti,P,V,Cr,Zr,Ba.Besides,the quality fraction of REE and the w(Fe_2O_3)/w(FeO)ratios are rather low.These geochemical characteristics reflect a special geological-tectonic environment. |
