In the case study of 101-4 ore body of Shihu Gold Deposit,the structural superimposed halo research samples in the roadways below 180 m level are collected and the deep geochemical element combination characteristics of the ore body are analyzed.The results show that As,Sb,Hg are typical head halo indicator elements,Au,Ag,Cu,Pb are typical near-ore halo indicator elements,Mo,Co,Bi are typical tail halo indicator elements;ore body axial zoning shows obvious reverse zoning characteristics,indicating that the metallogenic and halo-forming characteristics exhibit obvious superimposition;the 101-4 ore body has the characteristics of near-ore halo,intense,large and continuous in distribution,while the head and tail halos are relatively weak and small and poorly continuous in distribution.The head and tail halos have superimposition features.Based on the tendency that the geochemical parameter of head and tail halo element ratio decreases in the deep before rises,deep prospecting prediction is made using the blind ore prediction criteria of structural superimposed halo,and 3 prediction target areas are delineated.
