The characteristics of location rule and deep pfima~halo of Tongmugou copper deposit 3# ore body in Hujiayu of Shanxi Province have been studied��The results show that the ore body 3# occurs in the contact zone of silicified marble and carbonaceous slate of Bizigou Formation with southeastern inclining and northeastern lateral trending��The detachment faults within Bizigou Formation provide interspace for the movement of metallogeneic fluid and the unloading of minerals��The area from gentle to steep slope along the inclination is more favorable for mineralization��and the 525��445 m level is just located at the gentle area of fracture surface��and change to steep in deep��the axial zonality sequence of primary halo in 525-445 m can be concluded as(Sn-W-Sb)��(Mn-V-B-As-Ni)��(Pb-Ti-Ag-Co-Mo-Bi-Zn-Hg-Cu-Au)��The geochemical parameter “a”performs increasing trend��the distribution of front halo element enriches in lower part��which reflects that the ore body 3# may prolong downwards to a greater extent��and delineates the forecasting target area of deep ore body based on above analysis�� There exists the mineralization superposition of Cu and Mo in 445 m with seficite-quartz alteration prophyritic granodiorite��which is the sign of prophyritic Cu and Mo mineralization in deep��and the deep front halo element enrichment is also a representation of Mo hydrothermal superposition. Thus, the authors propose that the deep part of 445 m level is a prospective area to find Mo mineralization.
