Daobeizhuangzi gold deposit in Xiadian area in Jiaodong peninsula is strictly controlled by Zhaop-ing main fault zone.It has the characteristics of multi-stage and multi-stage superimposed mineraliza-tion.In this paper,the element geochemistry of the structural superimposed halo samples from No.27 and No.30 exploration lines in the mining area has been studied.It is showed that the axial zonation sequence of primary halo formed in a single stage of mineralization is As,Sb,Hg(leading halo)→ Au,Ag,Cu,Pb,Zn(near ore halo)→ Bi,Mo,W(tail halo).The phenomenon of coexistence of leading halo and tail halo occurs in the lower part of the ore body.Combining with the established structural superimposed halo model and blind ore prediction markers,one target location has been predicated in No.30 exploration line.It is indicated that ore bodies extend to the deep.It will provide an important reference for later deep ore prospecting and exploration.
