[en] For the sake of study geochemical behavior of active U, Th, Pb, Zn elements in rocks, an experiment on water-rock interaction between felsic crypto-explosive breccia and basement rock from uranium deposit No. 570 in north Fujian, uranium deposit No. 6722 in south Jiangxi, Yinshan Polymetallic deposit in Jiangxi is conducted with the solution conditions of pH=1.9, ΣS=3.2x10^-4, ΣCl=3.5 x 10^-4, ΣF=3 x 10^-5, t=90 degree C. The experiment result shows that U, Zn, Pb elements in rocks have stronger activation migration power, metasomatic alteration has important significance for the migration and enrichment of U, main ore formation material is not derived from felsic crypto-explosive breccia, and the basement rocks play an important role in ore formation
