REE GEOCHEMICAL CHARACTERISTICS AND ITS PALEOKARSTENVIRONMENTAL MARKS OF ORDOVICIAN IN NORTHERN ANHUI

    Graphical Abstract
    • Abstract
  • The REE contents of 14 samples selected from Ordovician carbonate sections in Xiao County,North Anhui have been investigated using ICP.Based on describing ∑REE,the distributed model of REE,characteristics and relations between LREE and HREE Eu and Ce,it is discussed in detail that the relation between REE geochemical characteristics and paleokarst development.The quantitative identification standards of karstic erosion degree and karstification environment are also preliminarily discussed.
