Footnote:φ=235U/204Pb;μ=238U/204Pb;subscript of d(t)represents testing value at time of ore-forming,meanwhile m(t)represents the mantle value at the same time which thought to be~20 Ma;All values are calculated by isoplot program(Ludwig,2003).Tho
At least six orebodies have been recognized in the studied area,all of which are controlled by N–S and NNE–SSW-striking normal faults(Table 1).The I,II,and III orebodies contain minor amounts of Pb and/or Sb mineralization,and are associated with the F1,F4,and F5faults,respectively.These orebodies contain mineralization that is confined to fracture zones,and contain relatively low grade of sulfides that incompletely fill spaces within the fault breccias.Although these faults extend for hundreds of meters(Table 1),the orebodies associated with these faults are small,with widths of 1–7m,lengths of 10–50 m,and maximum depths of 100 m.
