영문 초록

There is clear difference in content of the major and trace elements between Masan granites of Cu province and Yucheon-Eonyang granites of Pb-Zn province in the Yucheon Basin : the former has low content in K(2.08%), Na(2.42%) and Rb(127ppm), and high content in Ca(3.75%), Mg(1.42%) and Sr(304ppm) whereas the latter has high content in K(3.56-3.60%), Na(3.05-3.06%) and Rb(144-161ppm), and low content in Ca(0.62-0.96), Mg(0.21-0.26%) and Sr(136-157ppm). Ore metals in granites also show slight difference between two areas : Masan granites have slightly higher Cu content(18ppm) than Yucheon-Eonyang granites(13, 14ppm), whereas Yucheon granite(29ppm) has slightly higher Pb content than Masan granites(25ppm). Thus, it may be possible to apply geochemical difference of the granites to distinguish whether a Cretaceous granite mass is related to copper or lead-zinc mineralization, and whether it belongs Cu-province or Pb-Zn province in the Yucheon Basin.
