Abstract: Based on the investigation for geological characteristics of Xifengshan gold deposit, the significant q₆ gold-bearing quartz veinhas been selected to implement the primary halo geochemistry measure and abnormalities modeling. After testing and analyzing the 10 elements of q₆ gold-bearing quartz vein, the results show that the strength of Au primary halo in earth surface is greater than that in drilling and trench. The Au primary halo of q₆ in earth surface is extremely clear, which reaches the scale of primary halo in ore-body. And the horizontal zoning of Au primary halo in q₆ quartz vein is basically symmetrical, indicating the northern tendency to incline of ore-body. In addition, the sequence of the horizontal zoning above also reveals that the main elements formed mines have mighty strength as well as large scale line. The research on element distribution and change regularity in this major auriferous quartz vein can provide mighty proof of ore-body chase as well as project design in this area.
