Abstract: Paishanlou gold deposit is a large scale gold deposit located in ductile shear zone of greenstone area,with a feature of two three-stage mineralization superimposed. Considering the actual demands in production,a comprehensive geological and geochemical study on Paishanlou gold deposit is carried out by the new method of structural superimposed halo. It is shown that the front halo indicator elements of ore-body are As,Ba,Sb; The ore halo indicator elements are Pb,Au,Ag,Cu,Zn; Rear halo indicator elements are V,Bi,Mo,Co,Mn,Ti,W. Considering the geological-geochemical characteristics of temporal and spatial evolution,a structural superimposed halo model is established for predicting blind ore-bodies of Paishanlou gold deposit. And the geological sign and the structural superimposed halo signs of predicting the blind ore-bodies in Paishanlou gold deposit were summarized. Using the structural superimposed halo model and geological-structural superimposed halo signs,the east-west blind ore-bodies in Paishanlou deep deposit are successfully predicted.
